Alpine 3800 Series Switch

Power Supplies

This chapter describes:

• Important facts about the Alpine 3800 series power supplies

• Installation and removal procedures for the Alpine 3800 series power supplies

The Alpine 3800 series chassis accommodates two power supplies: AC and DC. If two

power supplies are installed in the switch, both installed power supplies must be of the

same type. The AC power supplies auto-sense for 110 VAC and 220 VAC power. The

DC power supplies require -40 VDC input line voltage. When two power supplies are

present, the power is load-shared between the supplies for enhanced longevity.

The power supplies for the Alpine 3808 are inserted into the front of the chassis. The

power supplies for the Alpine 3804 are inserted into the lower rear of the chassis. The

Alpine 3802 power supply is preinstalled at the factory and is not user-removable.

Table 8-1 describes the supported power supplies for the Alpine 3800 series switch.

The Alpine 3800 series switch generates SNMP traps for the following events:

• AC power source fails

• Power supply fails

• Power supply is removed
