Chapter 9 Replacement Procedures
Replacing an I/O Module
Step 13 Grasp the front of the module with one hand and place your other hand under the module to support its
weight.
Step 14 Align the module to the open supervisor slot in the chassis and push the module into the slot until it
makes contact with the midplane.
Step 15 Simultaneously push both ejector levers inward until they come in contact with the face of the module.
Step 16 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 this module and the next module.
Step 17 Screw in the two captive screws to the chassis and tighten them to 8 in-lb (0.9 N·m).
Step 18 Reconnect the console cable to the CONSOLE SERIAL PORT as explained in the “Connecting to the
Console” section on page 6-2.
Step 19 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 20 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 21 Reconnect the CMP cable to the CMP MGMT ETH port as explained in the “Connecting the Supervisor
CMP Port” section on page 6-5.
Step 22 Verify that the module has 4 GB of memory by using the system switchover command to make the
downgraded module active and using the show system resources command.
Step 23 If you need to downgrade the other supervisor module to 4 GB (both modules must have the same amount
of memory), repeat Steps 2 through 21.
Step 24 Verify that the downgraded module has 4 GB of memory. If there are two supervisor modules installed
in the switch, use the system switchover command to make the downgraded module active, and then use
the show system resources command. If there is just one supervisor module installed in the switch, use
the show system resources command.
Step 25 If you need to downgrade another supervisor module to 4 GB (both supervisor modules in a switch with
two supervisors must have the same amount of memory), repeat Steps 2 through 24.
Replacing an I/O Module
The Cisco Nexus 7010 switch has up to eight I/O modules, and a Cisco Nexus 7018 has up to 16 I/O
modules. These modules are located on the front of the chassis. You can replace one of these modules at
a time while the switch is operating.
Note If you are installing F2 I/O modules, all of the fabric modules in the switch must be Series 2 fabric
modules.
