NOTE:
•
As a best practice, use HPE QSFP+ transceiver modules, QSFP+ network cables, or QSFP+ to
SFP+ network cables for the QSFP+ ports on the switch. The HPE QSFP+ transceiver modules,
QSFP+ network cables, and QSFP+ to SFP+ network cables available for the interface modules
are subject to change over time. For the most recent list of QSFP+ transceiver modules, QSFP+
network cables, and QSFP+ to SFP+ network cables available for the interface modules, contact
Hewlett Packard Enterprise Support or marketing staff.
•
You can use a QSFP-40G-SR4-MM850 or QSFP-40G-CSR4-MM850 transceiver module to
connect a QSFP+ port to four SFP+ ports. The QSFP+ transceiver module and SFP+ transceiver
modules to be connected must be the same in specifications, including central wavelength and
fiber type.
For more information about HPE QSFP+ transceiver modules, QSFP+ network cables, and QSFP+
to SFP+ network cables, see

To avoid interference between cables, layer cables as follows:
•
Use category-6A or above cables and connectors.
•
Do not bundle cables in their first 20 m (65.62 ft).
•
Separate power cords and twisted pair cables at and around the distribution frame.
•
For ports adjacent to one another on the device, the peer ports on the distribution frame are
preferably not adjacent, for example:
{
If the device connects to one distribution frame, connect port 1 on the device to port 1 on the
distribution frame, port 2 on the device to port 3 on the distribution frame, and port 3 on the
device to port 5 on the distribution frame.
{
If the device connects to two distribution frames, connect port 1 on the device to port 1 on
distribution frame 1, port 2 on the device to port 1 on distribution frame 2, and port 3 on the
device to port 2 on distribution frame 1.
