Download firmware to a Nortel IP telephone
Firmware is the software stored in the telephone. When the system is upgraded with a new IP
telephone firmware load, this firmware load automatically downloads into the IP telephones when
the telephones next connect to the system.
The IP Terminal Details subpanel has a Force firmware download button that enables you to
initiate an immediate download to a telephone. You force a download in situations where
troubleshooting suggests that a particular telephone has corrupted firmware. Refer to
“IP telephone set details” in the BCM 4.0 Networking Configuration Guide (N0060606) for
details.
To force a firmware download to a Nortel IP telephone
1 You can access the reset button from two locations:
• Configuration > Resources > Telephony Resources > Terminal Details
• Configuration > Telephony > Sets > Active Sets > Capabilities and Preferences > IP
Terminal Details
2 Select an IP telephone from the list.
3 Click Force firmware download.
The system drops any active call on that telephone, and downloads a new firmware load into the
selected telephones. The telephone is unusable until the download is complete, and the telephone
has reset.
Note: The telephone is still configured to change when Daylight
Savings Time occurs, if the host system is programmed to change.
Therefore, if the telephone is in an area that stays on Standard Time year
round (for example, Saskatchewan, Canada), you must readjust the time
on your IP telephone at each time change. You must also readjust the
time if the IP telephone is in a time zone that changes, and the system is
not (for example, if the telephone is in Alberta, Canada, and the system
is located in Saskatchewan).
Note: In order not to saturate the IP network with download packets, the
system only downloads to a maximum of five IP telephones at any given
time. Telephones requiring download show an Element Manager status
of Download Pending. The UNISTIM Terminal Proxy Server (UTPS)
initiates download as resources become available.
