Host system operation should not be affected and normal use of the disk system can continue. Repair is needed but at a convenient time. An event that will not likely escalate to a severe condition if left uncorrected. Host system operation will not be interrupted and normal use of the disk system can continue. The problem can be repaired when convenient. An event that is expected as part of the normal operation of the hardware. No action is required.

User Defined Annotation: Enclosure 37 LCC A. Troubleshooting Troubleshooting 95 Status LEDs LEDs indicate the status of the disk system itself and each of its components (see Table 11). Green and amber system LEDs are visible on the front of the disk system. They show that power is on (green) and a fault has occurred (amber). Disk activity (green) LEDs are on the front of the disk drives at the bottom. Other LEDs are on individual components in the back of the disk system. LED states are described in Table 11: Table 11. LED Functions LED System Power Green OFF State Power is on. Power is off. Indication 96 Troubleshooting Table 11.

[. . . ] However, the limits of these specifications do not represent the optimum for long, trouble-free operation and specifically are not recommended for maximum satisfaction. The recommended conditions are stated when appropriate. Operating temperature: 5º C to 40º C (50º F to 104º F) Recommended: 20º C to 25. 5º C (68º F to 78º F) Maximum gradient: 20º C per hour (36º F per hour) Relative humidity: 20% to 80% noncondensing, max. wetbulb at 26º C Recommended: 30% to 50% noncondensing Altitude: 3000 m (10, 000 ft. ) Note For continuous, trouble-free operation, the disk system should NOT be operated at its maximum environmental limits for extended periods of time. Operating within the recommended operating range, a less stressful operating environment, ensures maximum reliability. The environmental limits in a nonoperating state (shipping and storage) are wider: Temperature: -40º C to 70º C (-40º F to 158º F) Maximum gradient: 24º C per hour (43. 2º F per hour) Relative humidity: 15% to 90% noncondensing Altitude: 4600 m (15, 000 ft. ) Acoustics Sound power: 7. 3 Bels Sound pressure at operator's position: 56. 3 dB(A) Safety Certifications UL listed, UL 1950:1995 ­ 3rd Edition CSA certified, C22. 2 No. [. . . ]
