Replacing an I/O Module

A Cisco Nexus 7000 Series device includes one or more of the following types of I/O modules:
•
•
•
You can replace each of these I/O modules with another module of the same type while the Cisco Nexus
7000 Series device is operational.To do this, you must first remove an I/O module from the chassis, then
install a new or replacement I/O module in the newly vacated slot within a couple of minutes to maintain
the designed airflow.
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
Warning
when servicing. Statement 1034
Caution Make sure that you wear an ESD wrist strap while you handle each I/O module. Hold the module only
on its carrier edges without touching any electronic circuitry, and place it on antistatic mats or antistatic
foam when it is not installed in the chassis.
Caution If you cannot immediately replace an I/O module, either leave the I/O module in its slot or replace it with
a blank module so the system airflow is not disrupted. Leaving an I/O module slot open for more than a
couple of minutes can disrupt the system airflow causing the system to overheat and shutdown.
To replace an I/O module, follow these steps:
Place antistatic mats or antistatic foam where you can place the old and new I/O modules. Choose a place

that prevents damage to the module while it is outside the chassis.
Place the replacement I/O module on an antistatic mat or antistatic foam.

48-port 10/100/1000 Ethernet module
48-port 1 Gigabit Ethernet SFP module
32-port 10 Gigabit Ethernet SFP+ module
For the 48-port 10/100/1000 Ethernet module, unplug each cable.
For the 48-port 1-Gigabit Ethernet module, remove the fiber-optic cables then remove the SFP
transceivers.
For the 32-port 10-Gigabit Ethernet module, remove the fiber-optic cables then remove the SFP+
transceivers.
To prevent contaminants from entering the fiber optic lines or transceivers, cover the fiber-optic
openings with a plug.
