Selecting the Cabling

Use the following guidelines when selecting cabling for the DC power supplies:
• Each DC power supply requires 6.5 A at -48 VDC nominal (or equivalent power between -40 and -70
VDC).
• For DC power and ground cables, use 14 AWG, high strand-count copper wire cable .
Use power cables with the specifications outlined in Table 40.

Attaching the Cabling and Supplying Power

After you receive your Alpine 3802, you need to attach the cabling so you can supply power to the
chassis. To attach the cable to the lugs, and then to the DC power supply, perform the following steps:
1 Attach the ESD strap that is provided to your wrist and connect the metal end of the ESD strap to
the ground receptacle that is located on the top-right corner of the switch front panel.
2 Ensure that the rack and chassis are grounded to protective earth ground.
