Using Redundantm - HP PROCURVE 6208M-SX Installation And Getting Started Manual

This chapter describes the redundant management modules and how to configure and manage them. Redundant
management modules provide increased routing capacity and failover for HP 9304M or HP 9308M Chassis
devices.
See the following sections for information:
• "Configuring the Redundant Management Parameters" on page 5-3
• "File Synchronization Between the Active and Standby Redundant Management Modules" on page 5-10
• "Switching Over to the Standby Redundant Management Module" on page 5-15
• "Temperature Sensor" on page 5-16
The redundant management modules are fully-functional CPU management modules for the HP 9304M or HP
9308M Chassis devices. You can use one or two redundant management modules in a these devices.
The redundant management modules provide increased route capacity for routing switches running Border
Gateway Protocol Version 4 (BGP4). In addition, the redundant management modules contain a configurable
temperature sensor that sends a Syslog message and SNMP trap if the temperature on the module exceeds a
specified warning level. The temperature sensor also can shut the module down automatically to prevent
damage.
You can use one or two redundant management modules in an HP 9304M or HP 9308M chassis. Using two
redundant management modules adds fault protection against system outage. The two modules work together as
active and standby management modules. If the active module becomes unavailable, the standby module
automatically takes over system operation.
You do not need to sacrifice port density when using redundant management modules. The redundant
management modules are available in the following configurations:
• 8-port 1000BaseSX module
• 8-port 1000BaseLX module
• 0-port module
