Chapter 9 Replacement Procedures
Replacing a Supervisor Module
Step 13 If you are inserting the module into a Cisco Nexus 7010 chassis, rotate the module 90 degrees clockwise.
Step 14 Align the module to the chassis guides for the vacated slot (slot 5 or 6 on a Cisco Nexus 7010 chassis or
slot 9 or 10 on a Cisco Nexus 7018 chassis), and slide the module part way into the slot.
Step 15 With one or both hands on the front of the module, push the module all the way into the slot until it seats
on the midplane connector.
Step 16 Slide the module into the slot until it seats on the midplane.
Step 17 Simultaneously push both ejector levers inward until they come in contact with the face of the module.
The module should be fully seated in the slot and the captive screws should be aligned with their holes
in the chassis. The EMI gasket should close the gap between the replacement module and the module in
the next slot.
Step 18 Screw in the two captive screws to the chassis and tighten them to 8 in-lb (0.9 N·m).
Step 19 Reconnect the console cable to the CONSOLE SERIAL PORT as explained in the “Connecting to the
Console” section on page 6-2.
Step 20 If the previous supervisor module was connected to an asynchronous device through a modem, connect
the modem cable to the COM1/AUX SERIAL PORT as explained in the “Connecting to the Console”
section on page 6-2.
Step 21 Reconnect the network management cable to the MGMT ETH port as explained in the “Setting Up the
Management Interface” section on page 6-4.
Step 22 Reconnect the CMP cable to the CMP MGMT ETH port as explained in the “Connecting the Supervisor
CMP Port” section on page 6-5.
Upgrading Memory for Supervisor Modules
The Cisco Nexus 7000 Series supervisor modules use either 4 GB or 8 GB of memory. For switches that
have two supervisor modules, each module must have the same amount of memory so that it can provide
redundant services for the other. In order to use 8 GB of memory, a switch must be running Cisco NX-OS
Release 5.1 or later release. If the switch is running an earlier release of Cisco NX-OS, the supervisor
modules must have only 4 GB of memory installed.
To determine the amount of memory installed in the active supervisor, use the show system resources
command as shown in Figure 9-1. To determine the amount of memory used by the standby supervisor
module, use the system switchover command to make that module active and then use the show system
resources command. Example 9-1 shows the output for the show system resources command. In this
example, the total memory usage is 4115768K (4 GB).

To determine which version of Cisco NX-OS that the switch is running, use the show version command.
