CAUTION
For the DC input circuit to the system of a 16-slot chassis (1800W supply), make sure there
is a UL-Listed 60 amp circuit breaker, minimum -48VDC, double pole, on the input lugs to the
power supply. The input wiring for connection to the product should be copper wire, 6 AWG,
marked VW-1, and rated minimum 90
ο
C.
CAUTION
For the NEBS-compliant installation of 16-slot chassis with AC and DC systems, use a ground
wire of at least 6 American Wire Gauge (AWG). The ground wire should have an
agency-approved crimped connector (provided with the device) attached to one end, with the
other end attached to building ground. The connector must be crimped with the proper tool,
allowing it to be connected to both ground screws on the enclosure. Before crimping the
ground wire into the provided ground lug, ensure the bare copper wire has been cleaned and
antioxidant is applied to the bare wire.
Unpacking the PowerConnect B-MLXe Series
The PowerConnect B-MLXe Series ships with several items. Review the items listed under “Items shipped with units”
on page 7, and verify the contents. If any items are missing, contact the place of purchase.
Remove your B-MLXe chassis from the shipping carton. Save the shipping carton and packing materials in case you
need to move or ship the chassis at a later time.

Preparing to mount a chassis in a rack
Because of the weight of a fully loaded PowerConnect B-MLXe Series chassis, Dell recommends mounting a chassis
in a rack before installing modules and AC power supplies if necessary.
In a standard 19-inch (EIA310-D) rack, you can install
•
Up to ten PowerConnect B-MLXe Series 4-slot chassis.
•
Up to six PowerConnect B-MLXe Series 8-slot chassis.
•
Up to three PowerConnect B-MLXe Series 16-slot chassis.
