Table 3–7 Power System Functional Summary

FRU

Functional Summary

Local Disk Converter
(LDC)

An LDC is located in each in-zone disk drawer. It provides
+12 Vdc with fast transit response and tolerance to short-term
loading during disk spinup. Also pr5 Vdc for power
logic, and EMI filtering for the 48 V bus.

It provides VTERM, which is a 5 V diode isolated output, and
current limited for powering the I/O bus terminators. Fusing is
included to prevent a fault on one LDC from loading the 48 V
bus and crashing the entire power system.

Front End Unit (FEU)
H7884-AA

Provides the main ac circuit breaker, and generates two +48 V
outputs:

•

Unswitched (DRCT) which supports the CAMP and Disk
Extender modules, LDCs, DC3, and DC5

•

Switched (SWD) which supports the interface modules, and
Console and Disk extender modules

Also provides programmable fan power output from +11 to +27
Vdc which allows the system to adjust the fan speed based on
system temperature. The PSC monitors the system temperature
through a thermal emulator in DC3, and sends fan speed
commands through the CAMP module to the FEU to adjust
the fan power output.

Power System
Controller (PSC)
H7851-AA

An I2C bus allows the PSC to write power status information
to the system, and provides a power fail signal (POK_H) to the
mass storage devices and I/O options. Receives commands from
the CAMP module to initiate the logic power on sequence by
commanding the FEU to turn on the +48 V switched output and
enable the DC3 and DC5 outputs.

The PSC also drives the power system visual status indicators.
It monitors system temperature through the thermal emulator in
DC3 and sends fan speed commands through the CAMP module
to the FEU for fan power and fan speed control. Provides a
warning when system temperatures are beyond the normal
operating range:

Green Zone = 5°C (41°F) to 52°C (126°F)
Yellow Zone = 5°C (41°F) to 62°C (144°F)
Red Zone = 5°C (41°F) to 75°C (167°F)

Initiates the power off sequence when system temperature
reaches the red zone.

The PSC monitors the centerplane voltages and initiates a power
off on an undervoltage fault; fires the crowbar and initiates a
power off on an overvoltage fault.

Also initiates a power off if the FEU indicates a 48 V output is
out of tolerance, or there is less than 4 millisecond of reserve
power, and on a fan failure. The PSC monitors the LDC status
and reports failures to the system.
