Status indicators
You can monitor DS2500 performance by observing various status indicators:
• Indicators on the front of each disk drive report individual disk drive status.
• Indicators on the front lower corner of the enclosure report overall DS2500 status.
• Indicators on the top rear of the EMU report overall DS2500 status (duplicates of the indicators
on the front of the enclosure).
• A status LED on each power supply/blower assembly verifies proper operation of the assembly.
• Status LEDs on each I/O module indicate the detection of transceiver signals and power.
• An audible alarm alerts you to an error condition.
Specific LED information is provided in the description of the individual components in Chapter 2 .
