Overview
Phihong’s midspans are Power over Ethernet (PoE) injectors with output options ranging from
15.4W to 95W per port. Available with 1, 2, 4, 8, 16 or 24 ports, Phihong’s midspans put out full
power every port with no need to manage power across ports.
By using the SNMPv2C (Simple Networking Management Protocol version 2C) protocol, users can
monitor and control the port status over their internet browser. Linking an Ethernet cable between
their midspan and management computer, locally or otherwise through a network switch, users
may manage certain functions including remote reset of powered devices. Users may connect to
their midspan using the DHCP client on the midspan which will create a dynamic hostname and IP
address unique to the network. Otherwise a Static IP address may be created by the user.
Internet browsers that users may choose from to access their Phihong midspans including:
Internet Explorers 7 and 8 found on Windows XP, Windows Vista and Windows 7. Mozilla Firefox,
Google Chrome, Opera and Safari may also be used. To update the firmware on your midspan,
only Microsoft XP or Vista may be used at this time. Please check www.phihong.com or www.
midspans.com for support updates or contact us at poe@phihongusa.com for additional questions
regarding compatibility. For SNMO interface, users may refer to the SNMP console manual for PC
requirements.
A default username and password come preset on your Phihong midspan. Entering “admin” in
both fields will allow users to gain access to customize their security settings. The default read-
only community string is “Phihong_read_only” and users may enter “Phihong” for the read-write
community field. Select tools that users may access through Phihong’s management interface is
port control (i.e. turn on/off), change access strings (hostname, username, password etc.), and set
IP Address to dynamic DHCP to allow it to be set automatically or Static as customized by the user.
Additionally, users may configure and send SNMPv2C TRAPs which are triggered on changes to
port status.
Phihong may release new firmware and updates at any time, so it is advised to check our websites
regularly for any updates that may affect your midspan. For the models listed on the cover page, two
firmware files are used. The first is POEA-x.x.x.bin which is uploaded to an internal microprocessor
under Windows TFTP command. The second is POEB-x.x.x.bin which is uploaded directly into an
internal EEPROM by entering http://hostmane/upload into your internet browser or by using web
<system tools>.
More detailed instruction may be found in this manual.

Power up Midspan:
In order to power up your midspan insert an AC power cord into the appropriate connector on the rear
of your midspan. Once the cord is connected to a universal or redundant power source the midspan
will turn on.
With AC power applied, the unit starts-up and all LEDs should illuminate. The device runs through
a quick power-on test, which takes a couple of seconds. During this period, all ports are initially
disabled and the port indicators light up. After completing the cold start, ports will operate under
normal conditions and the unit is ready to connect to powered devices.
2.5
LED Indicators:
Port LED:
Model POE75U-1UP-N-R has three LED indicators labeled “ON”, “FAULT”, and “CONNECT”. The
“ON” LED will illuminate a solid green to indicate that the AC connection is good and that unit is
sufficiently powered. The “CONNECT” LED will illuminate solid green if it detects a device that requires
more than 33.6W of power (12.5K-resistance). The “CONNECT” LED will illuminate a blinking green if
it detects a device requiring less than 33.6W of power (25K resistance) and will power in IEEE802.3at
mode. Should a fault occur with the connections; the yellow Fault LED will blink till the error is resolved.
For a full description of the LED diagnostics, please review the individual product datasheet on www.
phihong.com or www.midspans.com.
For the series of multiport midspans, for each port the left LED (as viewed from front) will be blinking
(green) if 25K-resistance load is detected, meaning that the powered device requires less than 33.6W
of power and the midspan has powered in “IEEE802.3at mode”. The LED will illuminate in solid green
if the powered device requires more than 33.6W of PoE and the midspan has powered up in Full
Power mode. The right LED will blink Yellow if a fault has occurred with the connection. No LEDs will
illuminate if the port is not connected.
NIC LED:
If both LEDs are off, it indicates that Midspan is disconnected from the network.
If the green LED is illuminated and the orange LED blinks, it indicates the Midspan is properly connected
to the network.

Configure network settings:
WARNING: Only the network administrator is allowed to perform this configuration.
Network settings on your midspan can be re-configured. Users can choose DHCP, where the midspan
will be automatically assigned an IP address by the network. The alternative option is to choose Static
which allowing the user to customize the IP address, IP Subnet Mask, Default Gateway, Primary DNS
and Secondary DNS. Users need to be aware that any incorrect settings will cause your midspan to
lose a valid network connection or may upset your network’s normal operation.
Figure 21: Network Settings Webpage
After clicking the Save button, a Reboot page (shown below) will be displayed to inform the user that
the Midspan needs to reboot in order to update for the new settings. The Reboot webpage will also

System Tools
This System Tools webpage allows user to execute the following 3 tasks:
1. Upload Firmware
Upload the binary file POEB-x.x.x.bin (web/SNMP image) into the midspan‘s internal EEPROM
directly. Note that if a new version of firmware is released, in order to update, you first must use the
Windows TFTP command to upload POEA-x.x.x.bin into the midspan‘s internal microprocessor,
then upload POEB-x.x.x.bin. Please review Chapter 5: Firmware Updating at Field for more details
regarding TFTP uploading.
To upload web/SNMP image, using the Browser button to locate file POEB-x.x.x.bin, then click on
the Upload button. If the upload is successful, a new page will display the message <Software
Update Successful>. Click on the link referencing the site main page to be redirected to the newly
updated controller.
2. Reboot Midspan.
In addition to the Reboot button, there is an input-box for time associated with the Reboot button.
The Seconds input-box specifies the time for the boot loader to wait for a TFTP firmware upload
after a power reset. Read Chapter 5: Firmware Updating at Field for more details regarding a TFTP
upload.
Choose 0 seconds for a normal reboot. If you have uploaded the POEA-x.x.x.bin via TFTP boot
load, then a value of at least 6 must be input prior to clicking the Reboot button, then the page will
be redirected to the Reboot webpage. Note that the POE ports will be turned off while the boot
loader is waiting for an upload, however, if a reboot of 0 seconds (fast reset) is selected, the power
across the ports in use will not experience any interruption.
3. Restore Defaults.
The Restore Defaults button restores midspan to the factory defaults, and redirects the user to the
Rebooting page.
Review the following default settings for your Phihong midspan.
hostname: phihong-xxxxxx where ‘xxxxxx’ is the last 6 characters of the midspan’s MAC address.
user name: admin (case sensitive)
password: admin (case sensitive)
DHCP: enabled

Midspan Monitoring and Control through MIB Browser --- SNMP Protocol
Simple Network Management Protocol (SNMP) is used most commonly in network management
systems to monitor network-attached devices for remote diagnostics. Users can monitor and control
Phihong midspans using the SNMPv2c protocol. There are many SNMP consoles available, with very
little difference between them; Phihong leaves the final choice to user preference. Users may obtain
all the SNMP MIB information shown in this manual in a txt file found in the support sections of our
websites: www.midspans.com and www.phihong.com.

4.3 Notes for using Phihong Midspan MIB
1. Although Phihong midspans using SNMPv2c protocol can also run under a SNMPv1 console with
the same MIB file, they will not operate with Phihong’s SNMPv3 MIB, as the MIB files are not the
same.
2. There is a tree node <network> in Phihong Midspan devices, which allows the network
administrator to change the settings of dhcpStatus, ipAddr, ipmask, defaultGetway, primaryDNS
and secondaryDNS. If these settings are changed; the OID <saveNewSettings> must be set at a
value of “0” to reboot the device and validate the new settings. For other events requiring a system
reboot, users can also set a value of ‘0’ to <saveNetSettings>, except for a TFTP upload (refer to
Chapter 5: Firmware updating at field). A TFTP upload requires a value greater than or equal to ‘6’
to validate the upload.
3. Although <hostname> should technically be listed under network, we place it into the <control>
section as it does not need a second step (rebooting) to be validated. <macAddr> which is read-
only and follows the same rebooting rule, is also in this section.

4.4
Using MG-SOFT MIB Browser to run Phihong Midspan
As an example, we have detailed instructions on how to operate a Phihong Midspan using the MG-
SOFT MIB browser. These instructions do not apply to all MIB browsers, please see instructions for
your specific browser if you don’t want to use this software.
4.4.1 Generate Phihong-POE-MIB module
It is assumed that MG-Soft MIB browser is already installed on your PC. For detailed operation
information, users can get help by choosing from the menu Help » User Manual when the MG-SOFT
MIB Browser is opened.
1. Open the MIB Browser and click the Continue button on the Welcome popup window. A Tip
of the Day window may pop-up for certain options in this browser. Users may choose to click
the little box in the lower left hand corner to stop these pop-ups.
2. Click the MIB tab; remove any MIB modules in the “Loaded MIB modules” by highlighting and
double clicking them.
3. Under the Action menu - open Run MIB Compiler.
4. In the MG-SOFT MIB Compiler window, click File then Compile…… then in the Open window,
browse for and open PHIHONG-POE-MIB.txt (users can get SNMP MIB rev 10/30/09 from the
support section on either www.phihong.com or www.midspans.com).
5. If compiling is successful, a Compiled MIB Modules window will be displayed. Click Save All
and click OK on the Browse for Folder window.
6. Close the MG-SOFT MIB Compiler window.
7. In the MG-SOFT MIB Browser window, click the circular arrow button (the middle one of 5
buttons right below the Loaded MIB modules window). This will update the MIB Browser
windows’ contents (including the newly compiled MIB module Phihong-POE-MIB).
8. In the lower window, click the tab MIB Modules. Locate the module < Phihong-POE-MIB >.
Highlighting and double clicking it will load it into the upper Loaded MIB modules window.
9. Also locate <RFC1213-MIB> and <SNMPv2-MIB>, load them into the upper Loaded MIB
modules window.
10.Now the setup for Phihong’s Midspan SNMP interface is complete.

Field Firmware Updating
Phihong is continuously updating our firmware to improve our systems. To ensure that you have the
most up-to-date firmware, please check with the support section of our websites: www.phihong.com
or www.midspans.com. Updates can be made from the user’s PC by installing two essential pieces
of software: POEA-x.x.bin and POEB-x.x.bin where x.x is the version number of the firmware. POEA-
x.x.bin is the main firmware to be loaded into internal microprocessor, while POEB-x.x.bin needs to be
loaded into internal EEPROM.
Update POEA-x.x.bin before updating POEB-x.x.bin.
The MIB is a pure SNMP interface and used to generate the Phihong-POE-MIB.smidb module. To
update the Phihong-POE-MIB.smidb module, refer to your SNMP console User Manual (See chapter
<4.4.1 Generate Phihong-POE-MIB module> to review this method using the MG-SOFT MIB Browser).
Some updating may only need 1 or 2 steps, based on any new firmware requirements as they become
available.
5.1. Updating Microprocessor Flash Contents with POEA-x.x.bin
The boot loader inside the Midspan is used to upload POEA-x.x.bin into the internal microprocessor
under Windows’ TFTP command. Windows XP always includes the TFTP utility. However, on Windows
Vista the TFTP utility must be added by setting Control Panel » Programs and Features » Turn windows
features on or off » TFTP client.
There are two “modes” in which the boot loader can listen for a TFTP firmware upload.
TFTP uploading (Application Entry Mode)
For normal network/internet/SNMP operations, users may use this Application Entry Mode to manage
TFTP uploading.
1. Power up the ready-to-upgrade POE unit and connect it to the Ethernet network. Make sure that
its TCP/IP feature is functioning. The boot loader will use its TFTP, ARP and ICMP services.
2. Open the Command Prompt Console by clicking Start » Programs » Accessories » Command
Prompt.
3. In the Command Prompt Console, type:
Tftp:phihong-xxxxxx put “C: \......\POEA-x.x.bin” as shown in the Fig. 5-1, make appropriate
Hostname/IP Address and file path changes, do not execute the TFTP command yet.
4. Because the boot loader always listens for 6 seconds after power-on for a TFTP firmware upload,
an appropriate waiting time must be set for after a reboot. Open web » System Tools and in the
same screen, enter a value greater than or equal to 6, in the box on the right of the Reboot button
(or Open SNMP …./network/, click on the OID <saveNewSettings>, set a value 6).

5. Reboot the midspan by clicking the Reboot button in the web controller (or clicking the first icon
on the upper left hand corner in Set – xxxxxx.0 window to validate the Set value for the SNMP
interface). Then quickly switch to the Command Prompt Console to execute TFTP.
6. If successful, the TFTP client will indicate how long the transfer took as well as the transfer rate.
7. After a successful write, the boot loader will quit after a few seconds and the POE unit will start to
execute the new application that was just loaded.
If the boot loading process is interrupted due to a network failure or user cancellation, the boot loading
may be resumed by simply retrying the TFTP command, provided the power is not cycled. However,
if the boot loading operation is interrupted due to power failure, the boot loading must be recovered
using the following TFTP Power-On Reset Entry Mode.

TFTP uploading (Power-On Reset Entry Mode)
If a valid main firmware is not loaded or a power failure occurred during TFTP uploading Application
Entry Mode, then the TFTP uploading Power-On Reset Entry Mode must be used. In this mode, the
Midspan device must use a default IP address 10.0.2.5 with a Subnet mask of 255.255.255.0 for a
TFTP upload. The procedure is as follows:
1. Configure the PC as a Static Mode by setting Start » Settings » Network Connections » Local
Area Connection » Properties » Internet Protocol (TCP/IP). In the Internet Protocol (TCP/IP)
Properties window, set a static IP as shown in Fig. 32.
Figure 33: Set static IP in Internet Protocol (TCP/IP) Properties window
2. Connect the midspan directly to the PC with a Cat5e cable (An older PC may need a crossover
Cat5 cable.)
3. In the Command Prompt Console, type the following command but do not execute it:
tftp 10.0.2.5 put “C: \......\POEA-x.x.bin” , make all the appropriate file path changes.
4. Power up the midspan. If the device is already powered, turn it off by unplugging it for several
seconds, and then reconnect it to a power source.
5. Once the green LED on management RJ45 port blinks 3 times, quickly press Enter to run the TFTP
command. It must be executed at the right moment as soon as the power turns on.
6. After a successful TFTP boot loading process, restore your PC’s Internet Protocol (TCP/IP) settings
to <Obtain an IP address automatically> and < Obtain DNS server address automatically > to
allow normal network activity.

5.2. Updating EEPROM Contents with POEB-x.x.bin
After the POEA-x.x.bin update is complete, the web/SNMP interface image POEB-x.x.bin needs to be
uploaded into the internal EEPROM. There are two methods to updating the POEB-x.x.bin.
Method One:
In the address bar of your internet browser, enter http://hostname/upload, where hostname is the
string corresponding to the Midspan IP address. Then use the Browse... button (see Fig.5.3 Upload in
Internet Explorer) to locate the file POEB-x.x.bin, then click the Upload button.
