ATTENTION

A module inserted into a wrong slot could be

damaged by improper voltages connected through

the wiring arm. Use keying bands to prevent

damage to the module.

Place your module in any slot in the chassis

except the leftmost slot, which is reserved for

processors or adapters.

Observe the following precautions

when inserting or removing keys:

• insert or remove keys with your

fingers

• make sure that key placement is

correct

Incorrect keying or the use of a tool

can result in damage to the

backplane connector and possible

system faults.

ATTENTION

Position the keying bands in the backplane connectors to correspond to

the key slots on the module.

You can change the position of these bands if

subsequent system design and rewiring makes

insertion of a different type of module necessary.
