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).
