OmniSwitch 9000
Chassis DC-to-DC (nominal -48 VDC input) Power Supply
OmniSwitch 9000 Series of switches support an enclosed 600watts DC single output power supply for worldwide use as a
maximum of up to N+1 power system configuration. The power supply is protected such that a short at the output to return does
not result in a fire hazard, or shock hazard to the power supply. The power supply recovers automatically. The power supply
design enables the removal and subsequent replacement of a defective power supply from an operating chassis, without
affecting the operation of the chassis itself. Neither switching off nor removing one supply nor installing and switching on
another supply causes the +24 VDC line on the backplane of the chassis to vary beyond the regulation limits. This assumes that
the system is configured for N+1 redundant operation. The power supply supports a hot swappable feature.

The AC-to-DC and the DC-to-DC power supplies can be mixed and matched in the same system.
“DC- to-DC” Power Supply: OS9-PS-0600D
This Power Supply will have the same electrical output characteristics as that of the AC-to-DC Power Supply with the
exception of the -48 VDC nominal input voltages. The use of this type of DC Power Supply is mainly intended for the
Telco’s/Carrier applications.
