Supervisor Modules
Supervisor modules are automatically powered up and started with the switch.
Cisco MDS 9200 Series switches have one supervisor module that includes an integrated 16-port switching module.
Cisco MDS 9500 Series switches have two supervisor modules--one in slot 5 (sup-1) and one in slot 6 (sup-2). When the switch powers up and both supervisor modules come up together, the module that enters the active mode is dependent on which of the two modules comes up first. The standby module constantly monitors the active module. If the active module fails, the standby module takes over without any impact to user traffic.
Switching Modules
Cisco MDS 9000 Family switches support any switching module in any non-supervisor slot. The switching module obtains its image from the supervisor module.
The interfaces in each module are ready to be configured when the module displays an ok status.
Viewing the State of a Module
The switching module goes through a testing and an initializing stage before displaying an ok status. Table 9-2 describes the possible states in which a module can exist.

Description
|
powered up
|
The hardware has electrical power. When the hardware is powered up, the software begins booting.
|
testing
|
The module has established connection with the supervisor and the switching module is performing bootup diagnostics.
|
initializing
|
The diagnostics have completed successfully and the configuration is being downloaded.
|
failure
|
The switch detects a switching module failure upon initialization and automatically attempts to power-cycle the module three times. After the third attempt it continues to display a failed state.
|
ok
|
The switch is ready to be configured.
|
power-denied
|
The switch detects insufficient power for a switching module to power up.
|
active
|
This module is the active supervisor module and the switch is ready to be configured.
|
HA-standby
|
This module is the standby supervisor module and that the HA switchover mechanism is enabled.
|
standby
|
This module is the standby supervisor module and the warm switchover mechanism is enabled.
|
To view the state of a module from Device Manager, choose Physical > Modules. The dialog box displays the status of every module.

Configuring EPLDs
Switches and directors in the Cisco MDS 9000 Family contain several electrically programmable logical devices (EPLDs) that provide hardware functionalities in all modules. Starting with Cisco MDS SAN-OS Release 1.2, EPLD image upgrades are periodically provided to include enhanced hardware functionality or to resolve known issues.
Tip Refer to the Cisco MDS SAN-OS Release Notes to verify if the EPLD has changed for the SAN-OS image version being used.
EPLDs can be upgraded or downgraded. When EPLDs are being upgraded or downgraded, the following guidelines and observations apply:
•You can individually update each module that is online. The EPLD update is only disruptive to the module being upgraded.
•If you interrupt an upgrade, the module must be upgraded again.
•The upgrade or downgrade can only be executed from the active supervisor module. While the active supervisor module cannot be updated, you can update the other modules individually.
•In Cisco MDS 9100 Series Fabric switches, be sure to specify 1 as the module number.
•Cisco MDS 9216 Switches do not support EPLD upgrades.
Caution Do not insert or remove any modules while an EPLD upgrade or downgrade is in progress.
Note Switches in the Cisco MDS 9100 Series do not support a forced EPLD upgrade. When you upgrade the EPLD module on these switches, you receive the following message:
Data traffic on the switch will stop now!! Do you want to continue (y/n)?
Refer to the Cisco MDS 9000 Family Configuration Guide for information on upgrading EPLDs.
