Hardware Installation

ICD 13—Standard Controller ICD-13/05 9 of 56

3.0 Hardware Installation

The next sections describe how to set up and test the hardware when it arrives. These

steps do not require the use of EPICS or VxWorks, thus they can be done before any

host workstation hardware is available if necessary. Installation should be done in the

order

1. Enclosure

2. Transition Module

3. CPU card

4. Other VME cards

There are several precautions that must be observed when handling and using VME

cards. Following them will prevent many problems.

• Always take measures against electrostatic discharge. Ground yourself before touch-

ing a VME card. Use a grounding cable if available or stand on a conductive mat.

Keep cards in electrostatic bags when not in use.

• Turn off the enclosure power before removing or installing a card.

• Install backplane jumpers in empty slots. Remove backplane jumpers in filled slots.

A simple rule is to fill the slots from the left to the right. For double slot cards install

backplane jumpers in the empty slot covered by the card.

• Set and verify all jumpers and switches on the card before inserting it into the slot.

• Read the installation manual for every card.

4.0 VME Enclosure

The VME enclosure, or crate, is the housing for the VME backplane, power supply, and

cooling fans. The enclosure provides power, electromagnetic shielding, and input/output

connections for the internal VME modules. The enclosure is designed to allow field

replacement of the internal modules without requiring the enclosure to be removed from

its rack or disassembled.

4.1 Description

The Standard Controller VME enclosure is the Elma Electronics System 12V-0920.

The enclosure has a 9U by 21-slot backplane, front-to-back air flow, rear mount transi-

tion modules, and numerous other features.[3]

4.2 Installation

Unpack the VME enclosure and inspect for visible damage that may have occurred dur-

ing shipping. The front cover of the enclosure may be opened by unscrewing the two

knurled knobs at the upper corners. The cover may be removed by unscrewing one of

the two bolts holding the hinges in place. The cover can then be slid off the other hinge,

and the extracted hinge can be reinstalled. The enclosure may be run with the front

cover removed, but for maximum cooling the cover should be in place. This should not

be a problem during development.
