7. Install transceivers
You can install or remove a transceiver from an SFP28/QSFP28 slot without having to power off the switch.
Hot swapping SFP/SFP+/SFP28/QSFP+/QSFP28 transceivers
Supported SFP/SFP+/SFP28/QSFP+/QSFP28 transceivers that you can install in your Aruba switch can be “hot
swapped”– removed and installed while the switch is receiving power. However, disconnect the network cables
from the SFP/SFP+/SFP28/QSFP+/QSFP28 transceivers before hot-swapping them.
When you replace an SFP/SFP+/SFP28/QSFP+/QSFP28 transceiver with another transceiver of a different type,
the switch may retain selected port-specific configuration settings that were configured for the replaced unit. Be
sure to validate or reconfigure port settings as required.
SFP/SFP+/SFP28/QSFP+/QSFP28 connections to devices with fixed speed/duplex configurations
When connecting a device to your switch port that contains a SFP/SFP+/SFP28/QSFP+/QSFP28 transceiver, the
speed and duplex settings of the switch port and the connected device must match. Otherwise, the device may not
link properly—you may not get a link. For some older network devices, the default speed/duplex settings may be
predefined (for example, to 1000 Mbps/Full Duplex), or otherwise set differently from the default configuration of
your switch. These setting differences may also apply to some older Hewlett Packard Enterprise devices. Because
of these default speed/duplex considerations, make sure that devices connected to your SFP/SFP+/SFP28/
QSFP+/QSFP28 ports are properly configured. At a minimum, make sure the configurations match.
• The transceivers operate only at full duplex. Half duplex operation is not supported.
• Ensure the network cable is NOT connected when you install or remove a transceiver.
Use only supported Aruba transceivers as shown in the ArubaOS-Switch and ArubaOS-CX
Transceiver Guide ( https://asp.arubanetworks.com/downloads ). The use of unsupported
transceivers may result in product malfunction.
