Supervisor-1 Modules

The Cisco MDS 9509 and 9506 Directors support up to two Supervisor-1 or Supervisor-2 modules that

can be installed in slots 5 and 6 only. The main functions and components of the Supervisor-1 modules

are as follows:

• Control and Management, page 1-21

• Crossbar Switching Fabric, page 1-22

• Processor, page 1-22

• Port Interfaces, page 1-22

• LEDs on the Supervisor-1 Module, page 1-23

Note Supervisor-1 is not supported on the Cisco MDS 9513 Director.

Figure 1-14 shows a Cisco MDS 9500 Series Supervisor-1 module.

The supervisor modules provide the following control and management features:

• A redundant central arbiter that provides traffic control and access fairness.

• A nondisruptive restart of a single failing process on the same supervisor.

A kernel service running on the supervisor module keeps track of the high availability policy of each

process and issues a restart when a process fails. The type of restart issued is based on the process’s

capability:

–

Warm or stateful (state is preserved)

–

Cold or stateless (state is not preserved)
