Juniper Networks EX4200 - Manual (Page 202)

The uplink module in EX3200 and EX4200 switches is a hot-removable and
hot-insertable FRU: You can remove and replace it without powering off the switch
or disrupting switch functions.
NOTE: If you have set an uplink module port as a Virtual Chassis port (VCP), removing
the uplink module breaks the setting. You must reset the port as a VCP after you
replace the module. See Setting an Uplink Module Port as a Virtual Chassis Port (CLI
Procedure).
Before you begin removing an uplink module from an EX3200 or EX4200 switch:
■ Ensure that you have taken the necessary precautions to prevent ESD damage
(see “Prevention of Electrostatic Discharge Damage on EX Series Switches” on
page 236).
■ If there are any transceivers installed in the uplink module, remove them before
you remove the uplink module. For instructions on removing transceivers, see
“Removing a Transceiver from an EX Series Switch” on page 177.
Ensure that you have the following parts and tools available to remove an uplink
module from an EX3200 or EX4200 switch:
■ Electrostatic discharge (ESD) grounding strap
■ Cross-head screwdriver (provided in the uplink module kit)
■ An antistatic bag or antistatic mat
To remove an uplink module from an EX3200 or EX4200 switch:
1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and
connect the strap to the ESD point on the chassis.
2. Loosen the screws that secure the flip-up door covering the uplink module slot
on the front panel of the switch by using the cross-head screwdriver provided
with the uplink module kit and flip the door upward.
3. Insert the ball end of the screwdriver in the keyhole on the front panel of the
uplink module and slide the screwdriver to the narrow part of the keyhole (see
Figure 70 on page 177).
CAUTION: Ensure the screwdriver does not slip out of the keyhole when you pull
the uplink module out of the switch chassis.
4. Using both hands, gently pull the screwdriver to slide the uplink module halfway
out of the chassis (see Figure 71 on page 177).
5. Place one hand under the uplink module to support it and slide it completely out
of the chassis.
6. Slide the screwdriver out of the keyhole.
7. Place the uplink module in an antistatic bag or on an antistatic mat placed on a
flat, stable surface.
