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 PS6210 array includes two hot-swappable Type 15 control modules.
One functioning control module is required for array operation. You access control modules from the
rear of the array.
Control Module Features
The Type 15 control module includes:
•
Two pairs of Ethernet ports with two shared LEDs indicating status and activity:
–
One pair of 10GBASE-T ports, labeled Ethernet 0 and Ethernet 1
–
One pair of SFP+ ports, labeled Ethernet 0 and Ethernet 1
Only one of two ports with the same numbered 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. See
Management Port on page 29
•
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 circumstances. See
•
One serial port (for use if no network access to the array is available).
•
A field-replaceable microSD card containing the PS Series firmware. The microSD card is
accessed from the rear of the control module.
•
A release button and latch to release the control module from the array for replacement. The
release lever has a switch that detects activation and prompts the array to save data to nonvolatile
storage, thereby protecting your data.

Do
mix control module types in an array. Always make sure both control modules are the same
type and color. See the latest PS Series
modules.
About Control Module Configurations
While an array can run using only one control module, it is not recommended because this
configuration creates a single point of failure. If the control module fails and no other module can
take over, all access to your volumes stops until the failure is repaired or the control module is
replaced.
