5. 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. 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).
