Chassis Description 25
DC Input Voltage Specification
The power supply will operate within all specified limits over the input voltage range outlined in
Table 9. The power supply will power-off if the DC input is less than -34 V DC.

Maximum input current is measured at the lowest input voltage that the power supply continues to operate. This is not to
be used for determining agency input current markings.
DC Output Current Specifications
The combined output power of all outputs will not exceed 350 W. Each output has a maximum and
minimum current rating shown in Table 10. The power supply meets both static and dynamic
voltage regulation requirements for the minimum dynamic loading conditions. The power supply
meets only the static load voltage regulation requirements for the minimum static load conditions.

Note: The maximum combined power of the 3.3 V and 5 V outputs is 150 W.
Peripheral Bay
The peripheral bay consists of the following two bays for removable media:
• Low profile media bay 1 – for a ½-inch Floppy drive
• Low profile media bay 2 – for a ½-inch CD-ROM drive
Hard Drive Tray
The hard drive tray supports two 3.5-inch x 1.0-inch Ultra160 SCSI hard disk drives (non-SCA).
The hard drive tray is designed to accept 15 K RPM (and below) hard drives that consume up to
18 Watts of power.
