Dell Force10 S60 Quick Start Manual page 16

WARNING: To prevent electrical shock, make sure the systems are grounded
properly. If you do not ground your equipment correctly, excessive emissions
may result. Use a qualified electrician to ensure that the power cables meet
your local electrical requirements.
WARNING: Electrostatic discharge (ESD) damage can occur if components
are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the systems and their components.
CAUTION: Remove the power cable from the modules prior to
removing the module itself. Power must not be connected prior to
insertion in the chassis.
WARNING: Prevent exposure and contact with hazardous voltages.
Do not attempt to operate this system with the safety cover removed.
CAUTION: The DC power supply comes with a 6-8inch cord with a
snap-in plug that attaches to the DC power supply and screw
terminals that attach to the main power. Dell Force10 recommends
using a longer cable, to ensure sufficient room.
CAUTION: The power supply is marked + 48V - . Connect the + (plus
sign) to the red cable on the 6-8 inch cord; the - (minus sign) connects
to the black cable. BE SURE TO connect the RED to RETURN and
connect the BLACK to -48V.
For a NEBS compliant installation, the AC power connections
NOTE:
must use a surge protection device (SPD) to protect the AC power supplies
from damage to excessive power line surges.
To comply with the GR-1089 Lightning Criteria for Equipment
NOTE:
Interfacing with AC Power Ports, an external surge protection device
(SPD) is intended to be used at the AC input of the router.
The DC power return conductor must be isolated from the chassis
NOTE:
or frame when connections to the power supply are made.
