A TX 4000C has several mechanical interlocks, called keys, that prevent the board from being inserted in an incompatible chassis. Keying protects the board and other devices in the chassis from damage.
Before you install TX 4000C boards, configure the keying of your chassis so that it is compatible with the TX 4000C keying. This keying helps ensure that you do not accidentally insert an incompatible board in the chassis.
This topic describes how to key the slots in your chassis for TX 4000C boards. For detailed information about CompactPCI chassis keying, refer to the CompactPCI Computer Telephony Specification PICMG 2.5 R1.0 and to the IEEE 1101.10.
Warning: |
To protect yourself and your equipment, allow only qualified personnel to install keying. The personnel must be familiar with the CompactPCI Computer Telephony Specification PICMG 2.5, R1.0 document. Dialogic is not responsible if you install a board and chassis keying has not been properly installed. |
The following illustration shows how the TX 4000C board keys are configured:
The following illustration shows some of the keying chambers in a CompactPCI chassis that you must configure for a TX 4000C. You must also key rear keying chambers A through F that are not shown.
Configure keying in your chassis as described in the following table:
