Verify basic system operation
Verify the basic system operation by checking the SYS LED. When operating normally, the SYS LED
should be on green. The following image illustrates the step:
Connect network cables
To connect network cables, do the following:
1.
Connect a 100 ohm category 5e (or better) twisted-pair cable to the 1000BASE-T RJ-45
management port.
2.
Connect network cables to QSFP28 interfaces:
l If you are connecting fiber optic cables, install QSFP28 fiber transceivers, and then connect
fiber optic cabling to the transceiver ports.
The following transceivers are supported:
o
CLR4 100G
o
LR4/LR4-lite 100G
o
CWDM4 100G
o
OpenOptic 100G
l If you are using twinax copper cables (DAC cables) for port connections, connect the QSFP28
transceivers on the end of the DAC cables directly into the QSFP28 slots.
You can configure the QSFP28 ports as single-lane 100G mode, dual-lane 50G mode, single-
lane 40G mode, four-lane 25G mode, or four-lane 10G mode. The following cable types are
supported:
o
100 GbE to QSFP28 100 GbE cable: 1 m, 2 m, and 3 m
o
100 GbE to 2 × QSFP28 50 GbE split cable (Y-cable): 1 m, 2 m, and 3 m
o
100 GbE to 4 × SFP28 25 GbE fanout cable: 1 m, 2 m, and 3 m
