Crossbar Switching Fabric The Cisco MDS 9500 Series supervisor modules provide an integrated crossbar switching fabric to connect all the switching modules. Single fabric configurations provide 720-Gbps full duplex speed with 80-Gbps full duplex bandwidth per switching module. Dual fabric configurations provide 1.4-Tbps speed with 160-Gbps full duplex bandwidth per switching module. The Cisco MDS 9500 Series supports redundant supervisor modules.

Each supervisor exchanges its own status and updates the signal quality error (SQE) status periodically.

Chapter 1
Product Overview
Supervisor Modules
If the kernel service cannot perform a warm restart of the process, it issues a cold restart.
A nondisruptive switchover from the active supervisor to a redundant standby without loss of traffic.
If the supervisor module has to be restarted, then the secondary supervisor (which is continuously
monitoring the primary) takes over. Once a switchover has occurred and the failed supervisor has
been replaced or restarted, operation does not switch back to the original primary supervisor, unless
it is forced to switch back or another failure occurs.
Crossbar Switching Fabric
The Cisco MDS 9500 Series supervisor modules provide an integrated crossbar switching fabric to
connect all the switching modules. Single fabric configurations provide 720-Gbps full duplex speed with
80-Gbps full duplex bandwidth per switching module. Dual fabric configurations provide 1.4-Tbps
speed with 160-Gbps full duplex bandwidth per switching module.
The Cisco MDS 9500 Series supports redundant supervisor modules. Upon power up with slots 5 and 6
active, the supervisors negotiate to determine which one is active and which is the standby supervisor.
Each supervisor exchanges its own status and updates the signal quality error (SQE) status periodically.
If the active supervisor becomes disabled, the standby supervisor switches over to become the active
supervisor.
Dual supervisor modules provide dual crossbar switching fabrics for redundancy.
Processor
The Supervisor-1 module contains a Pentium III class processor. It has the following memory
specifications:
Port Interfaces
The Supervisor-1 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
