ES4100.1 Chassis VME64x - User’s Guide 15
ETAS Functional Description
2.5 Slots
The chassis provides 21 slots at intervals of 4 HP. The slots are designed for stan-
dard eurocards in 100 mm x 160 mm size. The front panel height of the plug-in
boards measures 4 Us.
2.6 Backplane
The backplane of the chassis has 160 pins. The pin allocation complies with the
extended VMEbus standard VME64x. Both VME-standard boards and extended
VME64x-standard boards can be inserted.
2.7 Power Supply Unit
The power supply unit provides the vo3.3 V, +5 V, +12 V, and -12 V. The
power supply unit is designed as a wide range unit with an input voltage range
of 100...240 V AC and a frequency range of 50...60 Hz.
The supply voltages of the ES4100.1 Chassis VME64x backplane are protected by
fuses (see "Fuses" on page 18).
The regional requirements for power cords and order number are listed in Tab.
4-2 on page 22.
2.8 Ventilation Fan
The chassis is equipped with thermo-controlled ventilation fans. The air mass
flow adapts automatically to the heat emission of the boards and the ambient air
temperature.
A visible alert on the front panel lights up if at least one fan has failed.
CAUTION!
Please observe, that the maximum current consumption for the
respective supply voltages (3,3 V, 5 V, +/- 12 V, see Tab. 3-1
on page 19) is not exceeded in case of subsequently installed boards.
You can find the information on the current consumption of a board
in the corresponding User’s Guide for the board.
In case of nonobservance the ES4100.1 and built in boards may be
damaged and there is the danger of fire through overheating.
