WARNING: Prevent exposure and contact with hazardous voltages. Do not attempt to operate this system
with the safety cover removed.
CAUTION: Remove the power cable from the PSU prior to removing the PSU. Also, do not connect the power
cable before you insert the PSU in the chassis.
CAUTION: The DC PSU comes with a 6-8 inch power cord with a snap-in plug that attaches to the DC power
supply and screw terminals that attach to the main power. To ensure sufficient room, Dell Networking
recommends using a longer cable.
CAUTION: The power supply is marked + 48V -. Connect the + (plus sign) to the red cable on the 6-8 inch
cord; connect the - (minus sign) to the black cable on the 6-8 inch cord. BE SURE TO connect the RED cable
to RETURN and the BLACK cable to -48V.
NOTE: To comply with the GR-1089 Lightning Criteria for Equipment Interfacing with AC Power Ports, use an
external SPD at the AC input of the router.

Installing an AC or DC Power Supply

To install an AC or DC power supply, follow these steps:
NOTE: The PSU slides into the slot smoothly. Do not force a PSU into a slot as this may damage the PSU or
the S6000 chassis.
NOTE: Ensure that you correctly install the PSU. When you install the PSU correctly, the power connector is
on the left side of the PSU and the status LED is at the bottom of the PSU.
NOTE: If you use a single PSU, install a blank plate in the other PSU slot. Dell
using power supply 1 (PSU1) as the blank plate slot.
