SentinelRAID 170 Installation and Hardware Reference Manual

1.6.2 Cooling Requirements

Proper SR controller cooling is required to ensure that the temperature of the critical controller board components does not exceed the operational temperature range. The main components on the controller board that can overheat are:

ASIC 133

CPU

SCSI Chip(s)

The temperature of these items cannot exceed 80°C. Of the three items listed, the CPU will heat up the most. To pre-empt overheating of the CPU, a heat sink has been mounted on top of the CPU. The heat sink is separated from the CPU with thermal grease.

Prior to installing and powering on the SR controller, it is imperative that you ensure that there is sufficient cooling of the controller.

1.7. SR Controller Monitoring

The SR controller comes with a number of different monitoring methods that enable you to constantly be updated on the status of the controller and the storage array to which it is connected.

1.7.1 I2C Bus

The I2C bus allows for the status monitoring of a number of different devices like power supplies and cooling fans.

1.7.2 LED Indicators

The LCD front panel has three LED status indicators that show that the power is on, when there is activity on the I/O channels, and when an error message appears on the LCD screen itself.

1.7.3Firmware (FW) and RAIDWatch GUI

Firmware: The firmware is pre-installed software used to configure the controller. The FW can be accessed through either the front panel LCD module or a terminal emulation program that is installed on an external computer connected to the host.

RAIDWatch: RAIDWatch is a premier web-based graphics user interface (GUI) that can be installed on a remote computer and accessed via the web.
