Casio P460 manual Firmware Download, Introduction, Preferred Bank

Chapter 13 Maintenance

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).

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.

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.

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.

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.
