The 8-port SFP+ expansion module, the 8-port 10GBASE-T expansion module, and the
2-port QSFP+ expansion module in EX4550 switches are hot-removable and
hot-insertable field-replaceable units (FRUs): You can remove and replace these modules
without powering off the switch or disrupting switch functions.
You can install up to two expansion modules in the module slots; one each on the front
panel and the rear panel of an EX4550 switch chassis.
NOTE:
When an expansion module is installed in the switch or an existing
expansion module is replaced with another expansion module, the switch
detects the ports on the expansion module. The switch creates the required
interfaces when transceivers are installed in these ports.
Before you begin installing an expansion module in the switch, ensure that you have taken
the necessary precautions to prevent electrostatic discharge (ESD) damage (see
"Prevention of Electrostatic Discharge Damage" on page
Ensure that you have the following parts and tools available:
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
289).
