Introduction
Cooling
All RAIDStation7 Fibre Channel models feature three Advanced Cooling Mod-
ules (ACMs). The modules are mounted at the rear of the unit. In the event of
ACM failure, two ACMs are capable of cooling the entire Storage Array until a
replacement ACM is installed.

CAUTION: The failed ACM should be replaced as soon as possible in case
another ACM failure occurs.

Environmental Monitoring
The Versatile Environmental Monitor (VEM) monitors the ACMs, hard disk
drives, power supplies, and Storage Array shelf temperature.

model.
AC Power Supply
The RAIDStation7 Fibre Channel Storage Array uses two high performance, hot
swap AC power supply units. A single power supply is rated at 370 Watts peak.
Each power supply has greater than 500,000 hours Mean Time Between Failures
(MTBF). In the event one power supply fails, the second power supply can easily
power the entire Storage Array until the failed unit is replaced. A diagram of the
power supply unit is shown in Figure 1-4.
