Chapter 10 Installing or Replacing Components
Installing an I/O Module
Step 18 Reconnect the console cable to the CONSOLE SERIAL PORT as explained in the “Connecting to the
Console” section on page 7-2.
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 7-2.
Step 20 Reconnect the network management cable to the MGMT ETH port as explained in the “Setting Up the
Management Interface” section on page 7-4.
Step 21 Reconnect the CMP cable to the CMP MGMT ETH port as explained in the “Connecting the Supervisor
CMP Port” section on page 7-5.
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.
Installing an I/O Module
A Cisco Nexus 7004 switch has up to two I/O modules, a Cisco Nexus 7009 switch has up to seven I/O
modules, a 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.
This section describes how to replace I/O modules and includes the following topics:
• Required Tools, page 10-35
• Installing a New I/O Module, page 10-35

the I/O module.
