Upgrade Firmware on Programmable
Circuit Packs
You can download new firmware to specific, programmable circuit packs. Programmable circuit packs
have a “P” in their suffix. For example TN799DP is programmable, but TN799C is not. This
programmable capability reduces the need to physically remove circuit packs and return them to Avaya
for firmware updates.
You can download firmware to one or more programmable circuit packs of the same type residing within
the same configuration.
During this firmware download process, a firmware image is installed on a circuit pack in three steps:
1
The image is copied from an Avaya server over the Web to a local “staging area” — a PC or
server on the customer LAN.
2
The image is copied from the local staging area to the source circuit pack.
3
The image is downloaded from the source to the target with one of these methods:
— For a self download, the image is downloaded directly from RAM (the source) to flash
memory (the target) on the same circuit pack.
— For a C-LAN-distributed download, the image is downloaded from RAM (the source) on a
C-LAN circuit pack to flash memory (the target) on one or more separate circuit packs of
the same type.
Although different circuit packs have different potential roles in a firmware download, currently the
following circuit packs can participate in a firmware-download procedure. Additional circuit packs will
be added in the future.
•
TN799C or TN799DP—Control LAN (C-LAN)
•
TN2214CP orTN2224CP—2-Wire Digital Line DIG-LINE)
•
TN2302AP—IP Media Processor (IPMEDPRO)
•
TN771DP—Maintenance/Test (M/T-ANL)
•
TN464GP, TN2464BP, and TN2313AP—UDS1
•
TN2501AP—Voice Announcements over LAN (VAL)
See Table 29, Programmable Circuit-Pack Roles in Firmware Downloads, on page 716 for each circuit
pack’s roles in a firmware download.
