3 Maintaining Control Modules

A PS6000 array includes two hot-swappable control modules. One functioning

control module is required for array operation. You access control modules from

the rear of the array.

Each control module includes multiple Ethernet ports, a serial connector (for use

if there is no network access to the array), and a field-replaceable micro SD card

(running PS Series firmware).

Cache and NVRAM batteries are not field replaceable. For information about

replacing a cache or NVRAM battery, contact your PS Series service provider.

A PS6000 array includes two Type 7 control modules, which have one serial port

and four Ethernet ports.

Figure 3-1: Type 7 Control Module

Only one control module is active (serving network traffic) at one time. The

secondary (redundant) control module mirrors cache data from the active control

module. If the active control module fails, the secondary will take over network

operations.

Do not mix control module types in an array. Always make sure both control

modules are the same type and color. See the latest PS Series Release Notes for

information about other supported control modules.
