Replacing Memory on a Cisco Nexus
7000 Series I/O Module
Date: November 17, 2016
Part Number: 78-100406-01
This document describes how to replace the DIMM on a Cisco Nexus 7000 Series
I/O module.
Note Before you install, operate, or service the system, read the Cisco Nexus 7000
Series Regulatory Compliance and Safety Information for important safety
information.
Replacing a DIMM on an I/O Module
To replace a DIMM on a Cisco Nexus 7000 Series I/O module, follow these steps:

Step 1 Follow ESD procedures, which include wearing an ESD wrist strap and placing
antistatic foam or antistatic padding where you will place the I/O module while
working with it. Choose a location that prevents damage to the module while it is
outside the chassis.
Step 2 Disconnect each I/O cable and remove the SFP transceivers from the front of the
module to be removed.
Warning Invisible laser radiation may be omitted from disconnected fibers or
connectors. Do not stare into beams or view directly with optical instruments.
Statement 1051
Step 3 Completely unscrew both captive screws on the installed I/O module that you
need to upgrade.
Step 4 Press both ejector release buttons on the ends of the module to push out the ejector
levers and to disconnect the module.
Step 5 Simultaneously rotate the two ejector levers outward to unseat the module from
the midplane connector.
Step 6 With a hand on each ejector, pull the module part way out of its slot in the chassis.
Step 7 Grasp the front edge of the module and place your other hand under the module
to support its weight. Pull the module out of its slot.
Caution To prevent ESD damage, avoid touching the electronic circuitry and prevent
anything else from coming in contact with its circuitry.
Step 8 If you are removing the module from a Cisco 7010 chassis, rotate the module 90
degrees counterclockwise so that it is horizontal and you can see the circuitry
from above.
Step 9 If there is a metal cover on the back of the I/O module, remove all 14 screws
holding the metal cover in place and remove the metal cover before proceeding to
the next step. See Figure 1.

Step 10 On the memory slot on the front of the I/O module, rotate both spring clips out.
Step 11 Holding the edges of the DIMM with your fingers, slide it out of its memory slot
and place it in an antistatic bag. See Figure 2.

Step 12 Holding the replacement DIMM by its edges, align it to the memory slot and push
it into place until the spring clips click into the DIMM. See Figure 3.

Step 13 Rotate both ejector levers away from the front of the I/O module.
Step 14 If the I/O module had a metal cover, as shown in Figure 1, secure the metal cover
to the back of the I/O module by screwing in all the 14 screws before proceeding
to the next step.
Step 15 Grasp the front of the module with one hand and place your other hand under the
module to support its weight.

front of the I/O module, rotate both
spring clips out.
2Holding the DIMM by its edges,
align it to the second memory slot
and push it into place until the
spring clips click into the DIMM.

Step 16 Align the module to the open I/O slot in the chassis and push the module into the
slot until it makes contact with 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 this module and the next module.
Step 18 Screw in the two captive screws to the chassis and tighten them to 8 in-lb (0.9
Nm).
Step 19 Reconnect the copper (1000BASE-T) and fiber-optic (SFP, SFP+, FET, and X2)
I/O modules as explained in the “Connecting an I/O Module” section of the Cisco
Nexus 7000 Series Hardware Installation and Reference Guide.
Step 20 Verify that the module has 8 GB of memory by using the show system resources
command.
Step 21 If you need to replace the DIMM on another Cisco Nexus 7000 Series I/O module,
repeat Steps 2 through 18.
