Installing an Uplink Module in an EX3200 or EX4200 Switch
If your EX3200 or EX4200 switch includes an optional uplink module, you install it in the
switch's front panel. The different types of uplink modules are described in “Uplink
Modules in EX3200 and EX4200 Switches” on page 34.
Theuplink module in EX3200 and EX4200 switchesis 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 Settingan Uplink ModulePortasa Virtual Chassis Port (CLI Procedure).
NOTE: On an EX3200 switch, if you install a transceiver in an SFP uplink module or in
an SFP+ uplink modulewhenthe SFP+ uplink moduleis operating in the 1-gigabit mode,
a corresponding network port from the last four built-in ports is disabled. For example,
if you install an SFP or SFP+ transceiver in port 2 on the uplink module (ge-0/1/3), then
ge-0/0/23 is disabled. The disabled port is not listed in the output of show interface
commands.
When an SFP+ uplink module is operating in 10-gigabit mode:
•
Only the 10-gigabit ports (ports 0 and 2) are enabled.
•
You can use only SFP+ transceivers in those ports.
When an SFP+ uplink module is operating in 1-gigabit mode:
•
All four ports are enabled.
•
You can use only SFP transceivers in all four ports.
Before you begin installing an uplink module in 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).
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)
