Connecting the power cord for a PSR150-D1 power module
CAUTION:
•
Connect the other ends of the wires for a PSR150-D1 power module to a –48 VDC power source,
with the negative wire (
–
or
L–
) to the negative terminal (
–
) and the positive wire (
+
or
M/N
) to the
positive terminal (

).
•
To use an H3C RPS to supply power to the power module, use a compatible RPS power cord to
connect the RPS to the power module.
•
The power cord color code scheme in Figure 28 is for illustration only. The cable delivered for
your country or region might use a different color scheme. When you connect the power cord,
always identify the polarity symbol on its wires.
To connect the power cord for a PSR150-D1 power module:
1.
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 28 .
If you cannot insert the plug into the receptacle, re-orient the plug rather than use excessive
force to push it in.
2.
Tighten the screws on the plug with a flat-blade screwdriver to secure the plug in the power
receptacle. See callout 2 in
Figure 28 .
3.
Connect the other end of the power cord to a –48 VDC power source or an RPS.
