Extreme Networks Consolidated Hardware Guide 147

Installing the Alpine 3808 and the Alpine 3804

DC Power Supply

This section describes the steps to successfully install and power your Alpine 3808 or Alpine 3804 DC

power supply:

• Selecting the cabling

• Installing the DC power supply

• Attaching the cabling and supplying power

• Verifying a successful installation

For centralized DC power connections, install only in a restricted access area.

Selecting the Cabling

Use the following guidelines when selecting cabling for the DC power supplies:

• Each DC power supply requires 30 A (Alpine 3808) or 16.5 A (Alpine 3804) at -48 VDC nominal (or

equivalent power between -40 and -70 VDC).

• For DC power and ground cables, use 8 AWG, high-strand count copper wire cable (Alpine 3808) or

10 AWG, high-strand-count copper wire cable (Alpine 3804).

Use power cables with the specifications outlined in Table 40.

Installing the Power Supply

This section describes how to install a DC power supply for both the Alpine 3808 switch and the Alpine

3804 switch. The Alpine 3802 switch comes with DC power supplies that are preinstalled at the factory;

however, you must attach the cabling to the DC power supplies. See “Supplying Power to the Alpine

3802 DC Power Supply” on page 152 for more information.

NOTE

Ground the rack, mount the chassis in a rack, and ground the chassis before installing any switch

components. For more information about grounding the rack, see “Protective Grounding for the Rack” on
