Installing or Replacing Modules, Fan Trays, and Power Supplies
c) Press the two ejector buttons on the each side of the module (see Callout 2 in the above figure).
The two handles spring out part way from the front of the module.
d) Fully rotate the two handles away from the front of the module and pull on them to move the module part way out
of its slot.
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.
Caution
Do not touch any electrical circuitry on the removed I/O module. Handle the module only by its covered
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
You can replace a fan tray module during operations so long as there are at least two other fan tray modules
operating in the chassis. We recommend that you put a switch in fan tray maintenance mode before removing
a fan tray. You can also remove a fan tray in order to replace one of the two fabric modules installed behind
it. When not replacing a fan tray or a fabric module, there should be three fan trays operating in the chassis.
