1.3 Cooling
The 475 mini crate provides a side-to-side ( optional front-to-side or front-to-rear ) cooling air flow.
The fan tray is field removable.
Using a standard DC fan in push mode a high airflow and static back pressure is achieved. The
maximum fan speed is 3000rpm and can be reduced stepwise via front panel switch operation or
remote control to 1200rpm. The fan operation can be temperature controlled in case the 475 chassis is
outfitted with optional temperature probes. The fan speed is monitored and a fan fail circuit will shut
down power in case of failures.
1.4 Power Supply
The 475 mini crate is outfitted with either one or two cPCI-type 250W power supplies. Optionally
also 300W power supply versions are available. The power supplies are hot-swappable and can
operate in a redundant mode. No minimum load is required. The following table provides the output
current rating for the 250W power supply.
Voltage Minimum Typical Max Peak.
5V 0A 25A 33A 33A
3.3V 0A 18A 33A 33A
+12V
0A 5A 5.5A 6A
-12V 0A 0.5A 1A 1.5A
Notes: 1.Peak load less than 60sec. with duty cycle <10%.
2.Max. load is the continuous operating load of each rail. But the max. load of each rail can't
be drawn from all outputs at the same time.
Using a special internal power backplane additional filtering and current measurement is provided.
This internal board is also outfitted with crow bars for an active discharge on all DC lines in error
conditions and when powering down.
With the help of the CML Over Voltage (OV), Under Voltage (UV) and Over Current (OC) trip
points can be defined.
1.5 Display and CML00 Shelf Manager
For local and remote monitoring and control the 475 mini crate is outfitted with a CML00 shelf
manager and a high visibility alphanumeric display. In addition to the display of voltages / currents,
temperatures, fan speed and networking it is possible to program most of the chassis and power
supply settings using the front panel switches (see paragraph 2).
The CML00 allows full remote monitoring and control of power supply, fan and chassis parameters
via Ethernet (SNMP v2 and WWW) and offers the following features:

Remote or local switch ON/OFF
