Required Tools; Replacing A Redundant Supervisor Module During System Operations - Cisco Nexus 7000 Hardware Installation And Reference Manual

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.

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 a Redundant Supervisor Module During System Operations

During operations, one supervisor is active while the other (redundant) 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.
Note A replacement supervisor module comes with one DIMM (4 GB of memory) or, if your switch is running
Cisco NX-OS 5.1 (or later release), two DIMMs (8 GB of memory). If the switch not running a version
of Cisco NX-OS that is compatible with using 8 GB of memory, then you must use only one DIMM (do
not install an additional DIMM).
Caution If you cannot immediately replace a supervisor, either leave the supervisor in its slot until it can be
replaced or replace it with a blank module so the system airflow is not disrupted. If the system airflow
is disrupted for more than a couple of minutes, the system could overheat and shut down.
