Chapter 9 Replacement Procedures
Replacing a Cisco Nexus 7009 Fan Tray During Operations
Step 11
If you are inserting the module into a Cisco Nexus 7010 chassis, turn the module 90 degrees clockwise.
Step 12
With one hand holding each side of the module, align the backside of the module to the slot guides in
the vacated slot, and slide the module part way into the slot.
Caution
To prevent ESD damage, avoid touching the electronic circuitry and prevent anything else from coming
in contact with the circuitry.
Step 13
With one or both hands on the face of the module, push the module all the way into the slot until it seats
on the midplane connector. The EMI gasket will close the gap between this module and any module or
chassis edge that is immediately above the module that you just installed.
Step 14
Simultaneously push both ejector levers inward until they come in contact with the face of the module.
The captive screws should be aligned to their holes in the chassis.
Step 15
Tighten the two captive screws on the fabric module to 8 in-lb (0.9 N·m).
Step 16
If you replaced a Series 1 fabric module with a Series 2 fabric module, repeat this procedure until all of
the Series 1 fabric modules have been replaced with Series 2 fabric modules.
If you have replaced all of the Series 1 fabric modules with Series 2 fabric modules, you can then install
the F2 I/O modules (see the
“Replacing an I/O Module” section on page 9-25
).
Replacing a Cisco Nexus 7009 Fan Tray During Operations
The Cisco Nexus 7009 switch has one fan tray (part number N7K-C7009-FAN) that is located on the
backside of the chassis.
Warning
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
when servicing.
Statement 1034
The Cisco Nexus 7009 fan tray is designed to be removed and replaced during operations, but you should
replace the fan tray within a couple of minutes to maintain the designed system airflow.
Warning
When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the
fan blades completely stop before you remove the fan tray.
Statement 258
To replace a Cisco Nexus 7009 fan tray, follow these steps:
Step 1
Place an antistatic mat or antistatic foam where you can place two fan trays (the new fan tray and the one
that you will remove from the switch).
Choose a place that prevents damage to the fan trays while they are outside the chassis.
Step 2
Unpack and place the replacement fan tray on the antistatic mat or antistatic foam.
Step 3
With a hand on each of the ring handles at the top and bottom edges of the front of the fan tray,
simultaneously press the spring knob on each handle, and pull the fan tray part way out of the chassis.
Step 4
Place one hand under the fan tray to support its weight and the other hand on the handle on the middle
of the front of the module, and then pull the module fully out of the chassis.
