Selecting transceiver modules and cables
When you select transceiver modules and cables, follow these restrictions and guidelines:
•
Use Category 6A (or above) twisted-pair cables to connect 10GBase-T Ethernet ports in a short
distance.
•
Use SFP+ or QSFP+ DAC cables to connect SFP+ or QSFP+ ports in a short distance.
•
Use SFP+ or QSFP+ transceiver modules and fibers to connect SFP+ or QSFP+ ports in a long
distance.
•
The transceiver modules at the two ends of an IRF link must be the same type.
For more information about the SFP+ and QSFP+ transceiver modules, see the switch installation
guide and HPE Comware-Based Devices Transceiver Modules User Guide.
NOTE:
The transceiver modules and DAC cables available for the switch are subject to change over time.
For the most up-to-date list of IRF-capable transceiver modules and DAC cables, contact your
Hewlett Packard Enterprise sales representative.
10GBase-T Ethernet port restrictions
10GBase-T ports are available for IRF connection on the following switches:
•
(JG898A) HPE FlexFabric 5700-32XGT-8XG-2QSFP+ Switch.
•
(JG899A) HPE FlexFabric 5700-32XGT-8XG-2QSFP+ TAA-compliant Switch.
When you use the 10GBase-T Ethernet ports as IRF physical interfaces, follow these restrictions
and guidelines:
•
The 10GBase-T Ethernet ports are grouped by port number in order, starting from 1. Each
group contains four ports. If you use one port in a group for IRF links, you must also use all the
other ports in the group for IRF links. However, you can bind the ports to different IRF ports.
•
Before you bind a 10GBase-T Ethernet port to an IRF port or remove it from the IRF port, you
must shut down all the 10GBase-T Ethernet ports in the same group.
•
Bring up the ports after you complete the operation.
QSFP+ port restrictions
You can use a QSFP+ port as an IRF physical interface, or use the breakout SFP+ ports of the
QSFP+ port as IRF physical interfaces. To use the breakout SFP+ ports, you must use the using
tengige command to split the QSFP+ port into four 10-GE breakout interfaces.
When you use the breakout interfaces of a 40-GE port for IRF links, follow these restrictions and
guidelines:
•
You must use all or none of the four 10-GE breakout interfaces as IRF physical interfaces. The
four breakout interfaces can be bound to different IRF ports.
•
Before you bind one 10-GE breakout interface to an IRF port or remove it from the IRF port, you
must shut down all the other 10-GE breakout interfaces. If any of the breakout interfaces are in
up state, the bind or remove action will fail.
•
Bring up the breakout interfaces after you complete the operation.
SFP+ port restrictions
SFP+ ports on the switches in Table 2 are grouped and available for IRF connection.
