Control and Management

The Supervisor-2 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 service running on the Supervisor-2 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)

•A nondisruptive switchover from the active Supervisor-2 to a redundant standby without loss of traffic.

If the Supervisor-2 module has to be restarted, then the secondary Supervisor-2 (which is continuously monitoring the primary) takes over. Once a switchover has occurred and the failed Supervisor-2 has been replaced or restarted, operation does not switch back to the original primary Supervisor-2, unless it is forced to switch back or another failure occurs.

Processor

The Supervisor-2 module has a processor running at 1.4 GHz. It contains a PowerPC class processor and offers the following memory specifications:

Memory	Bytes
DRAM	1 GB
1 internal CompactFlash card1	512 MB
1 external CompactFlash slot2	NA3

1.The card stores software images.

2.The slot is for optional cards to store additional images, and for configuration, debugging, and syslog information.

3.NA = not applicable.

Port Interfaces

The Supervisor-2 module provides the following port interfaces:

•RS-232 (EIA/TIA-232) console port with an RJ-45 connection that you can use to:

–Configure the Cisco MDS 9500 Series from the CLI

–Monitor network statistics and errors

–Configure SNMP agent parameters

•RS-232 COM1 port with a DB-9 connector, which can be attached to a modem.

•Front panel triple speed (10/100/1000) management port with CTS function. This port is used as an out-of-band management port. There are two LEDs associated with it. The Link LED on the left side indicates the link status and the Activity LED on the right side blinks when there is traffic going through this port.
