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.
5.1.3 Controller 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.
