Connecting the power cord
WARNING!
Make sure the grounding cable has been correctly connected before powering on the switch.
Use Table 7 to identify the power cord connection procedures available for your switch.

AC-input: Connecting the AC power cord
RPS input: Connecting the switch to a
–52 to –55 VDC output RPS
Connecting the AC power cord
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Connect one end of the AC power cord to the AC-input power receptacle on the switch.
Figure 18 uses a 5120 24G SI switch for illustration.
3. Connect the other end of the AC power cord to the AC power outlet.

Connecting the switch to a
–52 to –55 VDC output RPS
This section applies to the 5120 24G PoE+ (370W) SI switch.
To connect these switches to the RPS that provides
–52 to –55 VDC output:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably 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 19 ).
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.
