Troubleshooting Information

This chapter includes basic troubleshooting information and best practice procedures to work with
an SGI Modular InfiniteStorage NAS system. This chapter covers the following troubleshooting
topics:
• Detecting Component Failures
• No Video
• Loss of System Setup Configuration
• Safe Power-Off
• Checking System Air Flow
Note: Some software products are protected with software license keys derived from the
Media Access Control (MAC) Ethernet address. If your system requires the replacement of a
NAS controller head (node) board, the MAC Ethernet address changes. If you are using such
a product, you must request a new license key after replacement of the MIS NAS node board.

Caution: Always re-install the chassis cover after you have accessed any internal components to
ensure proper airflow and cooling for the system. Failure to re-install the cover may cause thermal
over-temperature conditions and automatic shut-down of the system.
