SFP/SFP+/QSFP+ installation notes
Use only supported Aruba SFP/SFP+/QSFP+ transceivers
Non-Aruba SFP/SFP+/QSFP+ 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 ArubaOS-Switch and ArubaOS-CX Transceiver Guide in the Hewlett Packard Enterprise Support
Center at http://www.hpe.com/support/manuals.
• See the supported transceivers information in the QuickSpecs for your switch model at http://www.hpe.com/
networking, along with minimum software versions to support the listed transceivers:
1. Select Campus and Branch Networking.
2. Select Aruba Switches.
3. Select a switch model.
4. Select Product Details.
5. Select an option under QuickSpecs.
Hot swapping SFP/SFP+/QSFP+ transceivers
Supported SFP/SFP+/QSFP+ 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+/QSFP+ transceivers before hot-swapping them.
When you replace a SFP/SFP+/QSFP+ 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+/QSFP+ connections to devices with fixed speed/duplex configurations
When connecting a device to your switch port that contains a SFP/SFP+/QSFP+ 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+/ QSFP+ ports are
properly configured. At a minimum, make sure the configurations match.
Switch operating system software
For the latest software version supported by your switch, visit http://www.hpe.com/networking/software.
For software installation, see the ArubaOS-CX Fundamentals Guide and other software documentation for your
switch at http://www.hpe.com/support/manuals.
When selecting a fiber SFP/SFP+/QSFP+ 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 Laser Class 1 SFP/SFP+/QSFP+ transceiver.
To ensure proper operation of your switch, use only the Aruba SFP/SFP+/QSFP+ transceivers
supported by your switch.
