Chapter 9 Replacement Procedures
Replacing a Supervisor Module

Fault LED is not on or blinking.
If one or more of the Input or Output LEDs is not green or the Fault LED is lit or blinking, see the
“Troubleshooting a DC Power Supply Unit” section on page 8-3

For more information on the power supply unit LED states, see
Appendix D, “Chassis and Module
Replacing a Supervisor Module
The Cisco Nexus 7000 Series switches can be configured with one or two supervisor modules. If the
system has two supervisor modules, you can replace one of the supervisors while the other one manages
system operations. If the system has only one supervisor, you must bring the system down to replace the
supervisor module because the supervisor module is required for managing operations.
Caution
Make sure that you do not accidentally press one or more of the ejector release buttons on the I/O,
supervisor, and fabric modules. These buttons and their mechanical levers are designed so that you can
easily power down and remove these modules when you need to replace them. If you press one of these
buttons, the lever for that button releases from the front of the module, but the module remains
operational and connected to the system. If you press the other ejector button on the same module at the
same time as you press the first button or while the lever for the first button is released, the lever for the
second button releases, and the module powers down and disconnects from the system.
To minimize the chance of accidentally disconnecting a module with a released lever, press the lever
back toward the module until it clicks. If both levers are released, the system has disconnected and
powered down the module, and the STATUS LED will be unlit. To reconnect and power up the module,
either remove and reinsert the module in the chassis or use system commands to power it on.
This section describes how to replace supervisor modules and includes the following topics:
•
•
Replacing One of Two Supervisor Modules During System Operations, page 9-12
•
Replacing a Supervisor Module in a Single-Supervisor System, page 9-18
•
Upgrading Memory for Supervisor Modules, page 9-20
Required Tools
You need a flat-blade or number 2 Phillips-head screwdriver to loosen or tighten the captive screws on
the supervisor module.
Replacing One of Two Supervisor Modules During System Operations
During operations, one supervisor is active while the other supervisor is in standby mode. You can
replace either of these two supervisors. If you need to replace the active supervisor, it becomes the
standby supervisor as soon as you press its ejector buttons.
