Supplying Power to the Alpine 3802 DC Power Supply
The Alpine 3802 switch supports two DC power supplies that come preinstalled from the factory. To
power on the Alpine 3802 DC power supplies, complete the following tasks:
• Select the cabling
•
Attach the cables and supply power
For centralized DC power connections, install only in a restricted access area.
In the event of a power supply failure, contact Extreme Networks about servicing and replacing your
power supply.
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 32.
