Removing an Uplink Module from an EX4500 Switch
The uplink module in EX4500 switches is a hot-removable and hot-insertable field-replaceable unit (FRU): You can remove and replace it without powering off the switch or disrupting switch functions.
You can install up to two SFP+ uplink modules in an EX4500 switch. Both uplink modules install horizontally on the front of the chassis. See Front Panel of an EX4500 Switch.
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 on EX Series Switches).
- 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
- Phillips screwdriver, number 2
- A replacement uplink module or cover panel
- An antistatic bag or antistatic mat
 | Caution: Do not leave the uplink module slot empty for a long time while the switch is operational. Either replace the uplink module promptly or install a cover panel over the empty slot. |
To remove an uplink module from the switch (see Figure 1):
- Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
- Loosen the captive screws in the ejector levers using the Phillips screwdriver, number 2.
- Pull both the ejector levers outward until they are fully open.
- Using both hands, gently pull the ejector levers to slide the uplink module halfway out of the chassis.
- Using both hands, hold the front edge of the uplink module and slide it completely out of the chassis.
- Place the uplink module in an antistatic bag or on an antistatic mat placed on a flat, stable surface.
