74 Avaya P460 Installation and Maintenance Guide
One of the SPVs can operate as Standby automatically only if both of the following
conditions are fulfilled:
• The current chassis is the last one in which you inserted this SPV
• The current running SW images are the same version
Firmware Download
You can perform software download using the copy tftp command (see page 26
of the Avaya P460 Reference Guide) or the Avaya Software Update Manager (part of
the Avaya™ Multiservice Network Manager Suite).
L You can obtain the latest firmware from the Avaya support site at
http://www.support.avaya.com
Introduction
Each P460 Supervisor module has two firmware image banks (“A” and “B”) and
one Device Manager (Embedded Web) bank.
The download is on a per-chassis basis and the firmware is automatically loaded
into the standby Supervisor module (if configured) in addition to the active
Supervisor module.
L Firmware is not downloaded to a halted Supervisor module.
You download the firmware to each bank separately via the CLI. The download
progress is shown on the screen.
Preferred Bank
You can choose which firmware bank to boot from (preferred bank) using the set
boot bank command.
L Changing the preferred bank affects both SPVs.
Booting from the Alternate Firmware Bank
Push the ASB button together with both function switches on the SPV front panel to
boot from the alternate SW bank.
L If the SPVs were running in a Active-Standby configuration and ASB caused
SW incompatibility between the SPVs, the Standby SPV will switch to Halted
mode.
