To install an uplink module in an EX3200 or EX4200 switch (see Figure 49 on page 136):
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.
Loosen the screws that secure the flip-up door covering the empty uplink module
2.
slot on the front panel of the switch by using the cross-head screwdriver, flip the
door upward, and remove the blanking panel covering the empty uplink module slot.
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.
Flip the door down and tighten the screws by using the cross-head screwdriver.
5.
NOTE: If the switch does not detect the uplink module, see "Troubleshooting Uplink
Module Installation or Replacement on EX3200 and EX4200 Switches" on page 194.
