Environmental Monitoring

Chapter 4: Environmental Monitoring

This Chapter deals with the various methods used to monitor the RAIDStation7

Ultra160 SCSI Storage Array. There are two methods used:

• Versatile Environmental Monitor (VEM) - The VEM is a card that plugs into

the backplane of the Storage Array. The VEM monitors the ACMs, power

supply voltage outputs and enclosure temperature.

• Device Carrier LEDs - All device carriers have two LEDs on the front which

are driven by the VEM. These LEDs give details about the operational status

of the hard disk drives and power supplies.
