Monitoring About the ES Module The ES module, shown in Figure 3-1, is located on the rear of the Storage Enclosure, between the two APC modules. Yellow LED = ES/Alarm Fault ID Switch Green LED = ES/Alarm OK ES Module Figure 3-1 ES Module Alarm Mute Button The ES module receives and reports status information for the Storage Enclosure's APC modules, disk drives, and for the enclosure itself. The ES module receives and reports status through a two-wire serial bus that connects to the I/O module. It reports status using LEDs (on the APC modules, drive carriers, and enclosure) and an audible alarm. The ES module can also be used for downloading firmware. The ES module is hot-swappable, and removing it does not affect the data path. For more information, see Hot-swapping the ES Module on page 4-9. Silencing the Audible Alarm When an event occurs in the Storage Enclosure that triggers the audible alarm, you can turn off the alarm manually by pressing the Alarm Mute button on the ES module (shown in Figure 3-1.) Pressing the Alarm Mute button deactivates the alarm. The alarm remains deactivated until the ES module is reset or until another alarm occurs. Note: You can also silence the alarm using Adaptec Storage Examiner software. See the Installation and User's Guide on your Adaptec Storage Enclosure CD for detailed instructions. 3-2
