3 Maintaining Control Modules
A PS6010 array includes one or two hot-swappable Type 10 control modules. One
functioning control module is required for array operation. You access control
modules from the rear of the array.

Control Modules

The Type 10 control module includes:
• Two 10GE Ethernet ports, labeled Ethernet 0 and Ethernet 1
• One 10Mb/100Mbps port, labeled MANAGEMENT (for use only if you
configure a management network)
• One serial connector (for use if there is no network access to the array)
• A field-replaceable microSD card running the 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.
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.
