220 Vac Power Supplies - Extreme Networks Alpine 3804 Hardware Manual

BlackDiamond 6800 Series Switch Power Supplies
NOTE
If you install four power supplies in your BlackDiamond 6816 chassis, the power supplies will deliver full
redundancy.
The BlackDiamond 6800 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 BlackDiamond 6800
series switch power supplies, see Table 84 on page 304.

220 VAC Power Supplies

If you install a 220 VAC power supply into the BlackDiamond 6800 series chassis, 220 Volts of power is
required for full operation. If 110VAC power is supplied, some BlackDiamond I/O modules might not
power up. The MSM64i performs power calculations and powers up the maximum number of I/O
modules from left (slot 1) to right (slot 8) in the BlackDiamond 6808, or top (slot 1) to bottom (slot 4 in
the BlackDiamond 6804 and slot 16 in the BlackDiamond 6816). A module is skipped if that module is
not within the power budget. Using 110 VAC, only eight modules in the BlackDiamond 6816, four
modules in the BlackDiamond 6808, and two modules in the BlackDiamond 6804 are powered on.
The BlackDiamond switch does not support installing a combination of the old 220 VAC PSUs (part
number 50012) with the new iPower 220 VAC PSUs (part number 50021) in the same chassis.
The 220 VAC power supply ships with one L6-20P (locking) power cable.
220 VAC power supplies slide in from the front of the chassis, as illustrated in Figure 99.
