Using the cable tie to secure the AC power cord
Connecting the switch to a –48 VDC power source
CAUTION:
•
To connect the switch to a –48 VDC power source, you can only use a DC power cord provided by HP.
•
To connect a DC power cord to a –48 VDC power source, identify the positive (+) and negative (-) marks
on the two wires of the power cord to avoid connection mistakes.
To connect the switch to a –48 VDC power source:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Correctly orient the plug at one end of the cable with the power receptacle on the power supply,
and insert the plug into the power receptacle. See callout 1 in
Figure 24
.
If you cannot insert the plug into the receptacle, re-orient the plug rather than use excessive force
to push it in.
3.
Tighten the screws on the plug with a flat-blade screwdriver to secure the plug in the power
receptacle. See callout 2 in
Figure 24
.
4.
Connect the two wires at the other end of the power cord to a –48 VDC power source.
