Key the Backplane Connector
Place your module in any slot in the chassis except the leftmost slot that is reserved for
processors or adapters, noting that you:
• should position the keying bands in the backplane connectors to correspond to key
slots on the module so that you place the keying bands between 14…16 and 18…20.
• can change the position of these bands if subsequent system design and rewiring
makes insertion of a different type of module necessary.
ATTENTION
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.
