Connecting the switch to a –48 VDC power source
CAUTION:
•
You can only use an HPE DC power cord to connect the switch to a –48 VDC power source.
•
The power cord color code scheme in
is for illustration only. The cable delivered for
your country or region might use a different color scheme. When you connect a power cord,
always identify the polarity symbol on its wires.
To connect the switch to a –48 VDC power source:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Insert the DC connector into the DC power receptacle. See callout 1 in

The connector of the DC power cord and the DC power receptacle are foolproof. Make sure the
connector is correctly oriented.
3.
Use a flat-blade screwdriver to fasten the two screws on the DC plug to secure the plug to the
DC receptacle. See callout 2 in
.
