You can install up to two SFP+ uplink modules in an EX4500 switch. Both uplink modules install horizontally
on the front of the chassis. The uplink module slot on the left is PIC 1. The uplink module slot on the right
is PIC 2. See Figure 62 on page

Each SFP+ uplink module provides four ports. Each module can house four 10-gigabit small form-factor
pluggable (SFP+) transceivers or four 1-gigabit small form-factor pluggable (SFP) transceivers.
NOTE: When a new uplink module is installed in the switch or an existing uplink module is
replaced with another uplink module, the switch detects the newly installed uplink module. The
switch creates the required interfaces when new transceivers are installed in those ports.
Before you begin installing an uplink module in the switch, ensure that you have taken the necessary
precautions to prevent ESD damage (see
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.)
Phillips (+) screwdriver, number 2
To install an uplink module in an EX4500 switch (see
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, 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.
2. If the uplink module slot has a cover panel on it, pull one of the ejector levers on the cover panel inward,
to unseat the cover panel. Use this ejector lever to slide the cover panel out. Save the cover panel for
later use.
