Chapter 9 Replacement Procedures
Replacing an I/O Module
Required Tools
You need a flat-blade or number 2 Phillips-head screwdriver to loosen or tighten the captive screws on
the I/O module.
Replacing an I/O Module
A Cisco Nexus 7000 Series switch includes one or more of the following types of I/O modules:
•
48-port 10/100/1000 Ethernet module (N7K-M148GT-11)
•
48-port 10/100/1000 Ethernet module with XL option (N7K-M148GT-11L)
•
48-port 1-Gigabit Ethernet I/O module (N7K-M148GS-11)
•
48-port 1-Gigabit Ethernet I/O module with XL option (N7K-M148GS-11L)
•
48-port 1-/10-Gigabit Ethernet I/O modules with XL (N7K-F248XP-25)
•
32-port 10-Gigabit Ethernet I/O module (N7K-M132XP-12)
•
32-port 10-Gigabit Ethernet I/O module with XL option (N7K-M132XP-12L)
•
32-port 1- and 10-Gigabit Ethernet I/O module (N7K-F132XP-15)
•
8-port 10-Gigabit Ethernet I/O module with XL option (N7K-M108X2-12L)
You can replace each of these I/O modules with another module of the same type while the Cisco Nexus
7000 Series switch is operational. To do this action, you must first remove an I/O module from the
chassis, and then install a new or replacement I/O module in the newly vacated slot within a couple of
minutes to maintain the designed airflow.
Warning
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
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 repack it
in its original packing material 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 shut down.
To replace an I/O module, follow these steps:
Step 1
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.
Step 2
Unpack and place the replacement I/O module on an antistatic mat or antistatic foam.
Step 3
Disconnect each I/O cable from the front of the module by doing the following:
•
For the 48-port 10/100/1000 Ethernet I/O module (N7K-M148GT-11 and N7K-M148GT-11L),
unplug each cable.
