WARNING:
If you upgrade your system yourself, follow these precautions:
To prevent damage to the DEFINITY LAN Gateway system assembly, make sure that you have connected the system assembly adapter cables to the port connectors on the back of the switch (see Step 2 in Task 5: Install the DEFINITY LAN Gateway System Assembly in Chapter 2) 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).
For the same reason, do not cycle the power on the switch (for example, during switch acceptance tests) once the system assembly is inserted unless you have first shut down the DEFINITY LAN Gateway system. Refer to the maintenance screens in Chapter 3 for the shutdown procedure.
