Controller Maintenance

5.1. Controller Maintenance Overview

5.1.1 About Controller Maintenance

Constant monitoring and maintenance of your SR 170 controller will minimize downtime and preserve the working integrity of the controller for a longer period of time. If any of the controller components fail, they must be replaced as soon as possible.

5.1.2 User Serviceable Components

Most of the controller components are user serviceable, i.e., replaceable. The following components can be replaced in case of failure:

Daughter board

DIMM module

BBU module

BBU charger board

The LCD panel and the controller board very seldom fail and it is therefore not necessary to replace them. If either of these items fails, the whole controller box needs to be replaced.

5.1.3Controller Maintenance Considerations

Qualified engineers who are familiar with the SR controller should be the only ones who perform maintenance operations on the controller. If you are not familiar with the SR controller or with RAID appliance maintenance in general, it is strongly advised that you refer SR controller maintenance to a suitably qualified maintenance engineer.

When performing maintenance procedures on the controller, all safety regulations described in Chapter 2 must be strictly adhered to. Failure to adhere to these regulations may cause permanent, irreparable damage to the controller. It should especially be remembered that the controller board and the daughter board are very sensitive components that can be easily damaged.
