Installing a Brocade MLX-16 router
Connecting DC power
You can supply DC power to the Brocade MLX-16 router using a DC-to-DC power supply. For 1200W power supplies, DC power must
be supplied at 48 V and 40 A. For 1800W power supplies, DC power must be supplied at 48 V and 60 A. The DC-to-DC supply
provides the DC power to the router at 12 V and 100 A.
The procedure in this section is for qualified service personnel.
Follow these steps to connect a DC power source.
1. Use a #1 Phillips screwdriver to remove the two screws that hold the transparent cover over the power supply lugs, as shown in
Figure 58.

2. Use a #2 Phillips head screwdriver to remove the power lugs.
3. Crimp #8 AWG power supply wire into the power lugs and reconnect the power lugs to the power supply unit. Refer to
Figure 59.
For the NEBS-compliant installation of a Brocade router 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.
To ensure adequate bonding when attaching the ground lug, a minimum of 20 PSI of torque is required to
be applied to the mounting hardware used to attach the ground lug.
