associated illumination criteria.
Table 1-1. DXC-100PSX Indicator (Controller Module)
Indicator State Description
READY Flashing Green Protection Switch is powered up and the PSX Controller is
communicating with the System Manager Module (DSMC.2) in the
DXC-100.
Flashing Red PSX Controller is powered up, but not communicating with the
System Manager Module (DSMC.2) in the DXC-100.
OFF Protection Switch is not powered up or PSX Controller is not
operational.
If the READY LED is alternately flashing between red and green, the PSX
Controller Module is downloading software to memory.
DC Power Supply Module, DPC/DC
The DC Power Supply Module is designed to take -48VDC input power and use it
to supply 24VDC for fan operation and 5VDC for digital logic and relay operation.
The input power passes through a 2 Amp, 250V, fast acting fuse (designated as
F1) and an inrush current limiter.
The DXC-100PSX can be configured with either a single DC Power Supply Module
or optionally two power supplies for redundant operation. Two front-accessible,
full-height power supply slots are provided in the DXC-100PSX chassis; a
minimum of one power supply is required per DXC-100PSX nest.
Thumbscrews are provided at the top and bottom of the faceplate to secure the
module in the chassis and to make an electrical connection to frame ground for
regulatory emission compliance. See
2 Figure 1-2 for an illustration of a DC Power
Supply Module.
