Alpine 3800 Series Switch Power Supplies
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 83 on page 302.

Table 38 and Table 39 describe LEDs that pertain to power for the Alpine 3800 series switch.
Installing the Alpine 3808 and the Alpine 3804
AC Power Supply
This section describes how to install an AC power supply for either the Alpine 3808 or the Alpine 3804
switch. The Alpine 3802 switch power supply is preinstalled at the factory. The power supplies for the
Alpine 3808 switch are inserted into the front of the chassis. The power supplies for the Alpine 3804
switch are inserted into the lower rear of the chassis.
For centralized DC power connections, install only in a restricted access area.
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
