Install Transceivers
Hold the transceiver by its sides and gently insert it into the switch until it clicks into place. When a
transceiver is inserted, the switch authenticates it. This can take 1-3 seconds, with the worst case being 5
seconds.
n
The Aruba transceivers are Class 1 laser devices. Avoid direct eye exposure to the beam coming from the transmit
port.
n
The transceivers operate only at full duplex. Half duplex operation is not supported.
n
Use of supported genuine Aruba transceivers is always recommended. Non-Aruba SFP28/QSFP+/QSFP28
transceivers are not supported. Non-Aruba SFP/SFP+ transceivers can be used in unsupported transceiver mode,
but no support or warranty will be provided. Should you require additional transceivers, contact your Aruba sales
representative or an authorized reseller.
n
Always disconnect the network cable from a transceiver before installing it in the switch.
n
You can install or remove a transceiver from an SFP/QSFP slot without having to power off the switch.
n
For more transceiver support information for your switch model, see the
ArubaOS-Switch and ArubaOS-CX
Transceiver Guide

n
Support for ER4L and FR1 transceivers in JL720C pwr-to-prt configuration is limited to 35C max
ambient, ports 50 and 52 only, due to thermal constraints.
