25To 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 powerreceptacle. See callout 1 in Figure 32.If you cannot insert the connector into the receptacle, re-orient the connector rather than useexcessive force to push it in.3. Tighten the screws on the connector with a flat-blade screwdriver to secure the connector in theDC-input power receptacle. See callout 2 in Figure 32.4. Connect the other end of the power cord to the –48 VDC power source or an RPS.Figure 32 Connecting a power cord for the built-in DC power moduleConnecting the PSR150-A1/PSR150-A2The power cord connection procedure is the same for the PSR150-A1 and PSR150-A2 powermodules. 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 theAC-input power receptacle on the power module, and pull the bail latch leftwards (see Figure33).3. Connect one end of the AC power cord supplied with the power module to the AC-input powerreceptacle (see callout 1 in Figure 34).4. Pull the bail latch rightwards to secure the connector to the power receptacle (see callout 2in Figure 34).5. Connect the other end of the power cord to an AC power source.
