Replacing A Fan Tray - Cisco Nexus 7702 Hardware Installation Manual

Installing or Replacing Modules, Fan Trays, and Power Supplies
e) Place one hand under the module to support its weight, grasp the front of the module with the other hand, pull the
module fully out of its slot, and set the module on an antistatic surface.
Do not touch any electrical circuitry on the removed I/O module. Handle the module only by its covered
Caution
surfaces (front and bottom of the module) and always set the module on an antistatic surface when it is
not inside the chassis.
Step 2 Install the new I/O module in the open slot as follows:
a) Unpack the new I/O module, set it right side up on an antistatic surface (so that you can see the electrical components
from above the module), and inspect the module for damage.
If anything is damaged, contact your customer representative immediately.
b) Press the two eject buttons (one on each side of the module front) and rotate the handles away from the front of the
module.
c) Without touching any electronic circuitry, grasp the front of the I/O module with one hand, place your other hand
under the module to support its weight, and lift the module to the slot.
d) Align the back of the module to the guides inside the slot, and slide the module fully into the slot by pushing on the
front of the module.
If you push the module fully into the slot, you seat it onto its connectors inside the slot and the handles move part
way toward the front of the module. The front of the module should be 1/4 inch (0.6 cm) out of the slot.
e) Simultaneously rotate each of the two handles to the front of the module until they click.
As you rotate the handles to the front of the module, the module should move fully into the slot.
f) Verify that the front of the module is even with the fronts of the other installed I/O modules. If not, press both ejector
buttons, pull on the handles to partly remove the module, and repeat Steps 2d and 2e to reseat the module in the slot.
g) Screw in the two captive screws (one on each side of the module) to secure the module to the chassis. Tighten the
screws to 8 in-lb (0.9 N·m) of torque.
The Status module LED should be green. If not, see
states.
h) Attach networking cables to the I/O ports.
The LED for each port should be green. If not, see
states.

Replacing a Fan Tray

The switch can operate for two minutes without the fan tray that you are replacing.
Note
Before You Begin
• You must follow ESD protocols, including the following:
◦ You must wear a grounded ESD wristband (or other personal grounding device) whenever you
handle the electronic modules outside the grounded chassis.
◦ You must carry electronic modules by only their covered edges or handles. Do not touch their
electronic components.
