Power Supply Information Mounting OS6855-14/P14 and OS6855-U10 Switches Power Supply Information Before getting started, please note that OmniSwitch 6855 Series power supplies can be installed in a number of different configurations. For example: • Basic single system power, which provides minimum power requirements to the chassis, with no power supply redundancy/failover. • Redundant system power, which provides minimum power requirements to the chassis as well as power supply redundancy/failover. Two system power supplies (PS1 and PS2) are required for this configuration. • Basic system power with Power over Ethernet (PoE) support. This provides minimum power requirements to the chassis, as well as minimum power requirements to the PoE ports. Two power supplies-a system power supply (PS1) and a PoE-specific power supply-(PoE1) are required for this configuration. • Redundant system power with Power over Ethernet (PoE) support. This provides system power supply redundancy/failover in addition to PoE power redundancy. Four system power supplies-two system power supplies (PS1 and PS2) and two PoE-specific power supplies-(PoE1 and PoE2) are required for this configuration. Refer to the table below for typical power supply and power supply tray requirements for different configurations.

Power Supply Information
Before getting started, please note that OmniSwitch 6855 Series power supplies can be installed in a
number of different configurations. For example:
•
Basic single system power, which provides minimum power requirements to the chassis, with no power
supply redundancy/failover.
•
Redundant system power, which provides minimum power requirements to the chassis as well as
power supply redundancy/failover. Two system power supplies (PS1 and PS2) are required for this
configuration.
•
Basic system power with Power over Ethernet (PoE) support. This provides minimum power require-
ments to the chassis, as well as minimum power requirements to the PoE ports. Two power supplies—a
system power supply (PS1) and a PoE-specific power supply—(PoE1) are required for this configura-
tion.
•
Redundant system power with Power over Ethernet (PoE) support. This provides system power supply
redundancy/failover in addition to PoE power redundancy. Four system power supplies—two system
power supplies (PS1 and PS2) and two PoE-specific power supplies—(PoE1 and PoE2) are required
for this configuration.
Refer to the table below for typical power supply and power supply tray requirements for different
configurations.
