Power Supply Leds - Extreme Networks Alpine 3802 Hardware Installation Manual

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.
The Alpine 3800 series switch supports the power supply configurations listed in Table 25.

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
