NOTE: On an EX3200 switch, if you install a transceiver in an SFP uplink module or
in an SFP+ uplink module when the SFP+ uplink module is 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 to install an uplink module
in an EX3200 or EX4200 switch:
■
Electrostatic discharge (ESD) grounding strap
■
Cross-head screwdriver (provided in the uplink module kit)
To install an uplink module in an EX3200 or EX4200 switch (see Figure 49 on
page 135):
1.
Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and
connect the strap to the ESD point on the chassis.
2.
Loosen the screws that secure the flip-up door covering the empty uplink module
slot on the front panel of the switch by using the cross-head screwdriver, flip the
door upward, and remove the blanking panel covering the empty uplink module
slot.
NOTE: If you are removing an uplink module and installing another uplink module,
wait for at least 10 seconds after removing the uplink module before installing the
new or the same uplink module. If you do not wait for at least 10 seconds, the
interfaces on the uplink module might not come up.
3.
Taking care not to touch module components, pins, leads, or solder connections,
remove the uplink module from its bag.
