4. Handle of the uplink module
NOTE: When you install an uplink module in the switch or replace an uplink module with another
uplink module, the switch detects the ports on the uplink module. The switch creates the
required interfaces when transceivers are installed in these ports.
The SFP+ uplink module ports in EX4300 switches can operate either in 10-gigabit or in 1-gigabit mode
depending on the transceiver you install in them. The operang mode for an SFP+ uplink module is
shown in the output of the show chassis pic fpc-slot slot number pic-slot slot number command.
Each port on the uplink modules has a pair of LEDs that indicate the link acvity and status of the port.
See "Network Port, Built-In QSFP+ Port, Uplink Port, and Uplink Module Port LEDs on EX4300
Switches" on page 74 for details about the status and link acvity LEDs.
SFP+ uplink modules are shipped with dust covers installed in the ports. QSFP+ uplink module is
shipped with a dust cover installed in one of the ports.
