SFP LEDs
Status LEDs for the SFP ports are described in the following table.
XGE link LEDs
XGE link LEDs provide the link status for ports on each of the uplink modules, if
applicable. Optional XGE ports one (port 49) and two (port 50) are located in the
uplink module on the front panel. Optional XGE ports three (port 51) and four (port
52) are located in the uplink module on the rear panel.

LEDs for the XGE ports are described in the following table.
Optional uplink modules
You can install up to two port uplink modules, one on the front panel and one on
the rear panel. Each expansion slot accepts either an SFP+ Uplink Module or a
CX4 Uplink Module.
SFP+ Uplink Module
The SFP+ uplink module contains two 10 Gigabit Ethernet optical transceiver slots.
The SFP+ uplink module provides 10 GbE connectivity over fiber cable. The SFP+
slots require approved SFP+ optical transceivers. Transceivers can be purchased
separately.
CX4 Uplink Module
The CX4 uplink module is a 10 Gigabit Ethernet CX4 short range module. It
contains two 10 GbE CX4 ports.
The CX4 uplink module provides CX4 connectivity between the RackSwitch and
copper 10 GbE CX4 network devices. The CX4 ports support link spans up to 15
meters on appropriate CX4-grade copper cables.
