2 Installing a Brocade MLXe-4 router

Connecting DC power

You can provide DC power for the Brocade MLXe-4 router by installing a DC-to-DC power supply. The DC-to-DC supply converts 48V-DC input from a power source to 12V-DC for your router.

DANGER

The procedure in this section is for qualified service personnel.

NOTE

Because there are multiple power supply vendors, the LED layout on your DC power supply may differ from what is shown in Figure 50. However, the LED functions are identical.

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 50.

3.Crimp #8 AWG power supply wire into the power lugs and reconnect the lugs to the power supply unit. Refer to Figure 51.

CAUTION

For the NEBS-compliant installation of Brocade MLXe-4, Brocade MLXe--8, and Brocade MLXe-16 routers 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.
