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).
