Chapter 3: Maintenance
Precautions
Danger:
Hazardous energy levels are present inside the system when the system remains connected to
a power source. Be sure to follow the safety procedures in the owner's guide or service manual.
Warning:
Before replacing any component in the system, you must turn off the computer and disconnect
the AC power cord.
Caution:
Printed circuit boards and hard disk drives contain electronic components that are extremely
sensitive to static electricity. Ordinary amounts of static from your clothes or the work
environment can destroy components. Do not touch the components or any metal parts without
taking proper antistatic precautions. See
on page 29 for more
information.
Caution:
Avoid keeping the cover off for extended periods of time while the system is operating. The
cover must be installed to prevent automatic thermal shutdown.
Important:
For security purposes, CMS has a hardware authorization feature. During the initial CMS
feature authorization process, the system preserves information about the configuration and
hardware of the CMS system. The system periodically checks for changes to the motherboard,
IP address, or MAC address. If the system detects differences between the preserved CMS
hardware information and the current CMS hardware information, the CMS hardware feature is
reset to
not authorized
. This forces the
auth_set
command to be re-run. If, at any time, the
system displays a message that the
auth_set
command needs to be run, then the customer
must contact the Avaya Services personnel to run the
auth_set
command. The
auth_set
command requires a password that is only available to authorized Avaya personnel. Once the
auth_set
command has been re-run, the system preserves the new CMS hardware
information. To minimize downtime, the customer must make arrangements with Avaya
