Selecting The Cabling; Installing The Power Supply - Extreme Networks Summit Summit1i Hardware Installation Manual

Alpine 3800 Series Switch Power Supplies
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) at -48 VDC nominal
— 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)
— 10 AWG, high-strand-count copper wire cable (Alpine 3804)
Use power cables with the specifications outlined in Table 39.

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 135 for more information.
NOTE
Ground the rack, mount the chassis in a rack, and ground the chassis before installing any switch
components.
Complete the following tasks before installing any switch components:
• Ground the rack—For more information about grounding the rack, see "Protective Grounding for the
Rack" on page 46.
