Connecting the switch to a –52 to –55 VDC output RPS

This section applies to the 5500-24G-PoE+ EI (2 slots), 5500-24G-PoE+ EI TAA (2 slots), 5500-48G-PoE+ EI (2 slots), 5500-48G-PoE+ EI TAA (2 slots), 5500-24G-PoE+ SI (2 slots), and 5500-48G-PoE+ SI (2 slots) switches.

To connect these switches to the RPS that provides –52 to –55 VDC output:

1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well grounded.

2. Unpack the RPS cable shipped with the RPS, identify the plug for connecting to the switch, correctly orient the plug with the RPS receptacle on the switch chassis, and insert the plug into the receptacle (see callout 1 in Figure 21).

   The RPS 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 RPS receptacle (see callout 2 in Figure 21).

4. Connect the other end of the power cord to the RPS.
