3.7.4 Connecting a DC power cord to the PSR150-D1
To connect an AC power cord to the QX-S5524GT-4X1C, QX-S5548GT-4X1C, or
QX-S5524GP-4X1C use PSR150-D1 power supply module.
1) Wear an ESD wrist strap and make sure it makes good skin contact and is correctly
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 3-27).
The 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 3-27).
4) Connect the two wires at the other end of the power cord to a –48 VDC power source.
