OmniSwitch 6850 Series Power Supplies
OmniSwitch 6850 Series switches support the following power supplies:
• PS-510W-AC power supply (see “PS-510W-AC Power Supply” on page 2-75)
• PS-510W-AC-E power supply (see “PS-510W-AC-E Power Supply” on page 2-76)
• PS-360W-AC power supply (see “PS-360W-AC Power Supply” on page 2-77)
• PS-360W-AC-E power supply (see “PS-360W-AC-E Power Supply” on page 2-78)
• PS-126W-AC power supply (see “PS-126W-AC Power Supply” on page 2-79)
• PS-120W-DC power supply (see “PS-120W-DC Power Supply” on page 2-80)
Approximately 120W is dedicated to system power needed for the chassis and the rest of the power is
utilized for Power over Ethernet (PoE). The power supplies connect to the rear of the unit. There is a
power shelf provided with the unit that slides into the rear of the chassis and is used to hold the power
supplies. See the table below for valid configurations.
The power supplies can also be connected using a cable, in case there is a need for a less deep chassis. In
this case, the same power shelf can be mounted in the rack using the mounting ears (removable in case the
power supply needs to be plugged into the rear of the chassis).
Note. PoE units do not support the mixing of unlike power supplies (i.e. 360W and 510W). If unlike
power supplies are mixed or if an unsupported power supply (such as a 120W power supply) is used, a
console message and a trap are generated.
Note. Non-PoE units support the mixing of unlike power supplies (i.e. 126W AC and 120W DC).
