Maximizing Avaya P460 Availability

Introduction

In order to maximize availability of the Avaya P460 for applications such as VoIP, you can deploy a variety of redundancy mechanisms.

This chapter describes the Supervisor module and I/O module redundancy and power supply availability features.

M460ML-SPV Supervisor Module Redundancy

To enable supervisor redundancy, you need to install two M460ML-SPV Supervisor Modules in a P460 Chassis. Ensure that one Supervisor module is “Active” and that the second is “Standby”.

M460ML-SPV Supervisor Module Modes:

•Active – The Supervisor Module is operating

•Standby – This Supervisor Module is fully synchronized with the Active one and can replace it in the case of failure.

•Halted – This Supervisor Module is not synchronized with the Active one and cannot act as a standby module.

You can verify the Supervisor Module mode by:

•the ACT and OPR LED status (refer to Table 6.1)

•the show spv CLI command, or

•the P460 Manager.

Table 6.1 ACT and OPR LED Summary

ACT LED is...	OPR LED is...	M460ML-SPV Module mode
ON	ON	Active
