Introduction
Switches and directors in the Cisco MDS 9000 Family contain several electrical programmable logical devices (EPLDs) that provide hardware functionalities in all of the modules. As of Cisco MDS SAN-OS Release 1.2, EPLD image upgrades are periodically provided to include enhanced hardware functionality or to resolve known issues.
You do not need to update your EPLD image unless otherwise advised by TAC. For detailed functional image upgrade instructions, refer to the Cisco MDS 9000 Family CLI Configuration Guide and the Cisco MDS 9000 Family Command Reference. To download the EPLD image, go to the following URL:

Note
Note
Changes Since the Last Release
There is a new EPLD image associated with Cisco MDS SAN-OS Release 3.3(5a). The new EPLD image, m9000-epld-3.3.5a.img, supports the Supervisor-2A module.
There are no caveats associated with the new EPLD image.
Determining the EPLD Versions on Your Modules
You can determine the EPLD versions by using CLI commands. This section includes the following topics:
Module EPLD Versions
Use the show version module slot epld command to view all current EPLD versions on a specified module.

Clock Module EPLD Versions
Use the show version clock-module epld command to view current EPLD versions on the Cisco MDS 9513 clock modules. The following command output example shows available clock module EPLD versions.
Example 3 Displaying Clock Module EPLD Versions
switch# show version clock-module epldEPLD Device Version---------------------------------------Clock Controller (Clock A) 0x05Clock Controller (Clock B) 0x05Installing and Upgrading the EPLD Version
EPLDs can be installed, upgraded, or downgraded using CLI commands. This section includes the following topics:
•
•
Note
Please upgrade Power Management EPLD to version OxD or higher.
You may need to upgrade the Power Management EPLD for the supervisor modules to version OxD or higher to use the USB ports. After upgrading the Power Management EPLD, you must power cycle the supervisor modules by power cycling the chassis. This is a disruptive upgrade. To perform a nondisruptive upgrade, see "Upgrading the Power Management EPLD Nondisruptively".
Installing and Upgrading Module EPLDs
Use the install module module-number epld command to upgrade EPLD images for a module. The modules that can be upgraded with this command are the standby supervisor and the switching modules. To upgrade the modules, you must enter the install module module-number epld command from the active supervisor. The active supervisor cannot be upgraded, only the standby supervisor can be upgraded.
Example 4 Upgrading Module EPLDs
switch# install module 9 epld bootflash:m9000-epld.3.2.1.imgEPLD Curr Ver New Ver-------------------------------------------------------XBUS IO 0x07 0x07UD Flow Control 0x05 0x05PCI ASIC I/F 0x05 0x05PCI Bridge 0x05 0x07WARNING: Upgrade process could take upto 15 minutes.Module 9 will be powered down now!!Do you want to continue (y/n) ? y\ <------------------------------------------------------------progress twirlModule 9 EPLD upgrade is successfulIf you forcefully upgrade a module that is not online, all EPLDs are forcefully upgraded. If the module is not present in the switch, an error is returned. If the module is present, the upgrade process continues.
To upgrade a module that is not online but is present in the chassis, use the install module module-number epld command. The switch software prompts you to continue after reporting the module state. When you confirm your intention to continue, the upgrade continues.
switch# install module 2 epld bootflash:m9000-epld-2.01b.img\ <------------------------------------------------------------progress twirlModule 2 EPLD upgrade is successful
Note
Data traffic on the switch will stop now!!
Do you want to continue (y/n) ?
When you install a Supervisor-2 module on a Cisco MDS 9513 Director, the external crossbar module will be upgraded with the standby Supervisor-2 module if a new EPLD version for the external crossbar module is available. To upgrade the external crossbar module, you need to have the standby Supervisor-2 module present and run the install module module-number epld command from the active supervisor module.
Example 5 Upgrading External Crossbar Modules
switch# install module 8 epld bootflash:m9000-epld-3.2.1.imgEPLD Curr Ver New Ver-------------------------------------------------------Power Manager 0x0c 0x0eXBUS IO 0x0a 0x0bFabric Controller 1 0x09 0x0bWARNING: Upgrade process could take up to 15 minutes.Module 8 will be powered down now!!Do you want to continue (y/n) ?y-Module 8 EPLD upgrade is successful
Note
Upgrading the Power Management EPLD Nondisruptively
To upgrade the Power Management EPLD on supervisor modules in a nondisruptive manner, follow these steps:
Step 1
After the EPLD upgrade is complete, the standby supervisor module will reboot.
Step 2
The standby supervisor module will come up with the new Power Management EPLD version.
Step 3
Step 4
Installing or Upgrading Clock Module EPLDs
Use the install clock-module epld url command on the active supervisor module to upgrade EPLD images for the clock modules. After upgrading the clock modules, power cycle the entire chassis for the change to take effect. Rebooting the chassis is not enough for the changes to take effect; you must turn off and turn on the chassis.
Example 6 Upgrading Clock Module EPLDs
switch# install clock-module epld bootflash:m9000-epld-3.2.1.imgLen 3184500, CS 0x04, string MDS series EPLD image, built on Thu Jul 19 16:50:07 2007EPLD Curr Ver New Ver-------------------------------------------------------Clock Controller 0x03 0x05There are some newer versions of EPLDs in the image!Do you want to continue (y/n) ? yProceeding to program Clock Module B.Do you want to switchover Clock Modules after programming Clock Module B.System Will Reset! y/n) ?n|Clock Module B EPLD upgrade is successful.A Cisco MDS 9513 Director switch has two clock modules that can be upgraded. The EPLD upgrade utility only upgrades the standby clock module. You can check to see which clock module is in standby mode by entering the show environment command.
Example 7 Upgrading standby clock module
switch# show environmentClock:----------------------------------------------------------Clock Model Hw Status----------------------------------------------------------A DS-C9513-CL 0.101 Ok/StandbyB DS-C9513-CL 0.101 Ok/Active
During the upgrade of the standby clock module the EPLD upgrade prompts you for the switchover of the clock modules. If you choose to allow the clock module switchover, the switch will reboot. After the switch reboots, enter the show environment command to verify that the previous active clock module is now the standby clock module.You can continue to upgrade the new standby clock module and allow a clock switchover to return the clock modules to their previous active and standby states.
Guidelines and Limitations
When you upgrade or downgrade the EPLDs, observe the following guidelines and limitations:
