3 Maintaining Control Modules

Different PS Series array models contain different control module types. The combination of chassis type,

control module pair, and drives determines the PS Series array model number.

The control modules in a PS Series array contain the PS Series firmware which provides the Group Manager

GUI, the command line interface, and all the array and storage management functions and features.

Ideally, an array has two control modules (which must be of the same type) to avoid a single point of failure for

the array.

A PS4110 array includes one or two hot-swappable Type 17 control modules.

One functioning control module is required for array operation. You access control modules from the rear of the

array.

The Type 17 control module includes:

•

Two 10G Ethernet ports, both labeled Ethernet 0. Each port has its own LEDs indicating status and activity:

–

One 10GBASE-T port

–

One SFP+ port

Note:

Only one 10G Ethernet port can be used at a time. If both ports are attached to an active switch, the

control module will prefer to communicate over the SFP+ interface.

•

One 10Mb/100Mbps port, labeled MANAGEMENT - for use only if you configure a management network.

The management port has two LEDs to indicate status and activity.

•

A column of LEDs labeled PWR (power), ERR (error condition) and ACT (activity) that indicate the status

of the control module.

•

A recessed button labeled STANDBY ON/OFF that allows you to quickly shut down the array in certain cir-

cumstances. See

About the Standby On/Off Button on page 22

•

One serial port (for use if there is no network access to the array).

•

A field-replaceable microSD card containing the PS Series firmware. The microSD card is accessed from

the rear of the control module.
