To install an uplink module in the switch (see
and Figure 75 on page 243):
Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and
1.
connect the strap to the ESD point on the chassis.
If a grounding strap is not available, hold the uplink module in its antistatic bag in one
hand and touch the exposed, bare metal of the switch with the other hand to ground
yourself and the component.
If the uplink module slot has a cover panel on it, loosen both captive screws on the
2.
faceplate of the uplink module by using your fingers. If you are unable to unscrew the
captive screws by using your fingers, use the screwdriver. Hold both the captive screws
and gently pull it outward to remove the cover panel, and save it for later use.
NOTE: If you are removing an uplink module and installing another uplink
module, wait for at least 10 seconds after removing the uplink module
before installing the new or the same uplink module. If you do not wait for
at least 10 seconds, the interfaces on the uplink module might not come
up.
Taking care not to touch module components, pins, leads, or solder connections,
3.
remove the uplink module from its bag.
CAUTION: Before you slide the uplink module into the slot on the switch
chassis, ensure the uplink module is aligned correctly. Misalignment might
cause the pins to bend, making the uplink module unusable.
Using both hands, place the module in the empty slot and slide it in gently until it is
4.
fully seated.
Tighten both the captive screws by using your fingers or the screwdriver.
