Hardware Installation
This section describes the tasks needed to install the DEFINITY LAN Gateway

The DEFINITY LAN Gateway system installation tasks are the same for all
switch types. These tasks include:
Task 5: Install the DEFINITY LAN Gateway system assembly

Task 9: Finalize and test the hardware
Before beginning these tasks, refer to the following worksheets:

!
WARNING:
To prevent damage to the DEFINITY LAN Gateway system assembly,
make sure that you (or the factory, for new switches) have connected the
system assembly adapter cables to the port connectors on the back of the
switch (as described in Step 3) before you insert the system assembly in
the switch carrier.
You can install the system assembly in the switch when the switch is
powered on or off. When the assembly is inserted in the slots of the switch
carrier, it will automatically power up, run diagnostics, and boot. To avoid a
disk crash, never remove the assembly without first completing the
shutdown procedure to shut down the DEFINITY LAN Gateway system
(and allowing the disk to completely spin down).
