Nortel Networks MOG6xx - Manual (Page 31)

Overview
If too many wireless handsets are attempting to download new firmware simultaneously, the
downloads can slow down or error messages can be returned. To reduce the number of retries and
error messages, manage the download process by staggering the times the wireless handsets
download the firmware.
The TFTP Server must be capable of supporting multiple TFTP sessions.
Nortel Networks has tested the following TFTP Servers. They are listed in order of preference.
•
Nortel Networks TFTP Server (Optical Network Management System [ONMS] application)
• 3COM TFTP
• PumpkinTFTP
• SolarWinds TFTP
WLAN Handset 2210/2211 firmware upgrade
Assuming the IP address of the TFTP Server has been configured on the
WLAN Handsets 2210/2211, each time a WLAN handset is powered on, the following occurs:
1 The WLAN handset checks its version of firmware against the firmware on the TFTP Server,
which takes less than two seconds on a quiet network.
2 If the firmware versions are different, the WLAN handset downloads the new firmware from
the TFTP Server. This process takes about 30 seconds.
3 If the TFTP Server is offline or unreachable, the WLAN handset tries for about ten seconds
before giving up and using its existing version of firmware.
DHCP Server
For detailed DHCP Server instructions, refer to the Configuring DHCP chapter of the
Programming Operations Guide (N0008589).
DHCP is a standardized protocol that enables clients to be dynamically assigned with various
configuration parameters, such as:
•
IP address
• subnet mask
• default Gateway
• other critical network configuration information
DHCP Servers centrally manage such configuration data, and are configured by network
administrators with settings that are appropriate for a given network environment.
