Connect Equipment to the Ports and Power On the System
1-32 D000102-000 B
1. Connect a Category 5 or 6 (Cat 5/6) Ethernet cable to the RJ-45 connector(s)
on the switch. Connect the other end of the Cat 5/6 to an OOB LAN workstation,
another switch or a hub.
2. Connect the switch to IB-enabled host(s)/switch(es) using QDR QSFP IB
cables, or to DDR host(s)/switch(es) using a QSFP-CX4 cable.
NOTE:
Make sure all cables latch securely into the corresponding port connectors.
If the IB cable connector is not properly oriented to fit onto the port
receptacle (i.e., while attempting to insert the cable in the port), do not twist
the connector to achieve the correct orientation. Instead, reach back a few
feet on the cable, and twist the bulk cable to allow the connector to rotate to
the proper orientation. Doing this prevents all of the rotational forces from
acting right at the connector terminations.
CAUTION!
It is important to provide strain relief for the IB cable connector.
Connecting Power
1. Provide strain relief for the power cable(s).
NOTE:For the 12800 switches, make certain the DC On switch is illuminated. If
it is not, press the button to supply power.
2. If necessary, replace the fascia(s) over the switch fans.
3. Connect the power cables to an AC power outlet.
4. When the switch is plugged into an AC power outlet:
a. The system powers up.
b. The fans start.
c. The system performs a power-on self test (POST).
NOTE:
For the 12800 switches, make certain the DC ON/OFF switch is illuminated.
If it is not, press the button to supply power. The switch is located:
 12800-360: Next to the AC power inlets on the top of the chassis.
 12800-180: Next to the power supplies. If applicable, the user needs to
remove the fascia covering the supplies to access the DC ON/OFF
switch.
