Installing an Uplink Module in 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. The uplink module slot on the left is PIC 1.
The uplink module slot on the right is PIC 2. See
Figure 38 on page 127 .

Uplink Module
(PIC 1) Uplink Module
(PIC 2)
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
“Prevention of Electrostatic
Discharge Damage” on page 250 ).
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.)
•
