To insert a module into an I/O chassis, follow these steps:
1. Remove power from the I/O chassis before inserting or removing a
module.
2. Open the module locking latch on the I/O chassis and insert the
module into the slot keyed for it.
3. Press the module firmly to seat it into its backplane connector.
4. Secure the module in place with the module locking latch.
CAUTION: Do not force a module into a backplane connector;
if you cannot seat a module with firm pressure, check the
alignment and keying. Forcing a module can damage the
backplane connector or the module.
