Removing an Uplink Module from an EX4200 Switch

If your EX4200 switch includes an optional uplink module, it is installed in the switch's front panel. The different types of uplink modules are described in Uplink Modules in EX4200 Switches.

The uplink module in EX4200 switches is a hot-removable and hot-insertable unit (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 on an EX4200 Switch as a Virtual Chassis Port (CLI Procedure).

Before you begin removing an uplink module from the switch:

• Ensure that you have taken the necessary precautions to prevent ESD damage (see Prevention of Electrostatic Discharge Damage).
• 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.

Ensure that you have the following parts and tools available:

• Electrostatic discharge (ESD) grounding strap (If a grounding strap is not available, follow the alternative grounding method described in Step 1 of the following procedure.)
• Cross-head screwdriver (provided in the uplink module kit)
• An antistatic bag or antistatic mat

To remove an uplink module from the switch:

1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.

   If a grounding strap is not available, touch the exposed, bare metal of the switch with the other hand to ground yourself and the component.

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 1).

   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 2).
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.
