Connecting the PSR150-D1
ARNING!
• H3C DC power cords are required if the –48 VDC power source is used. RPS power cords are required
if the RPS power source is used.
• Identify the positive (+) and negative (-) marks on the two wires to avoid connection mistakes.
To connect the PSR150-D1:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Unpack the DC power cord, correctly orient the plug at one end of the cable with the power
receptacle on the power module, and insert the plug into the power receptacle (see callout 1
in Figure 45).
T
he power receptacle is foolproof. 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 45).
