The AC power supplies auto-sense for 110 VAC and 220 VAC power. The DC power supplies require
-48 V DC nominal input line voltage. When two power supplies are present, the power is load-shared
between the supplies for enhanced longevity.
AC Power Supply Cords
An AC power cord is not included with the Alpine AC power supply. To purchase an AC power cord,
contact your local Extreme Networks Channel Account Manager or Sales Manager, or purchase a cord
from your local supplier. All power supply cords must meet the requirements listed in “Power Cable”
on page 310.
The Alpine 3800 series switch supports the power supply configurations listed in Table 25.
1 All installation, maintenance, and removal of a power supply must be done by qualified, trained service personnel only.
2 If you have one AC power supply installed in the Alpine 3802 switch, it must be installed in the lower power supply tray
(PSU A).
3 If you require DC power supplies in the Alpine 3802 switch, you must have two DC power supplies installed.
The Alpine 3800 series switch generates SNMP traps for the following events:
• AC power source fails
• Power supply fails
• Power supply is removed
For more information about planning your site and power requirements, see “Meeting Power
Requirements” in Chapter 2. For more information about the specifications of the Alpine 3800 series
switch power supplies, see Table 82 on page 331.
