SFP/SFP+ installation notes
When selecting a fiber SFP/SFP+ device, make sure it can function at a maximum temperature that is not less
than the recommended maximum operational temperature of the product. Use only an approved Class 1 Laser
Product SFP/SFP+ transceiver.
To ensure proper operation of your switch, use only the HPE Aruba SFP/SFP+ transceivers supported by your
switch.
Use only supported Aruba SFP/SFP+ transceivers
Non-Aruba SFP/SFP+ transceivers are not supported. Use of supported Aruba products ensures that
your network maintains optimal performance and reliability. If you require additional transceivers,
contact an Aruba sales representative or an authorized reseller. The following resources can help you to
find transceiver support information for your switch model:

See the Transceiver Guide.

See the supported transceivers information in the Data Sheet for your switch model.
Hot swapping SFP/SFP+ transceivers
Supported SFP/SFP+ 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+ transceivers before hot-swapping them.
When you replace a SFP/SFP+ 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+ connections to devices with fixed speed/duplex configurations
When connecting a device to your switch port that contains a SFP/SFP+ 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 such that they are set differently from the default configuration of your
switch. (For example, 1000 Mbps/Full Duplex.) These setting differences may also apply to some older
Hewlett Packard Enterprise devices. Because of these default speed/duplex considerations, make sure
