To connect a power cord for the built-in DC power module:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Correctly orient the power cord connector and insert the connector into the DC-input power
receptacle. See callout 1 in Figure 32.
If you cannot inse
rt the connector into the receptacle, re-orient the connector rather than use
excessive force to push it in.
3. Tighten the screws on the connector with a flat-blade screwdriver to secure the connector in the
DC-input power receptacle. See callout 2 in Figure 32.
4. Con
nect the other end of the power cord to the –48 VDC power source or an RPS.

Connecting the PSR150-A1/PSR150-A2
The power cord connection procedure is the same for the PSR150-A1 and PSR150-A2 power
modules. The following procedure uses the PSR150-A1 power module as an example.
To connect the PSR150-A1:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Attach two ends of the bail latch (supplied with the power module) into the two holes next to the
AC-input power receptacle on the power module, and pull the bail latch leftwards (see Figure
33).
3. Connect one end of the AC power cord supplied with the power module to the AC-input power
receptacle (see callout 1 in Figure 34).
4. Pull the bail latch rightwards to secure the connector to the power receptacle (see callout 2
in Figure 34).
5. Connect the other end of the power cord to an AC power source.
