The V: drive stores media. It also stores media file system, database, and configuration information.
K2 Summit systems with direct-connect storage or shared SAN storage do not contain disk modules,
as the V: drive is on the external RAID storage devices.
When configured as RAID 1, you can remove and replace a disk module while the K2 Summit
system is operational.

Power supply modules
The K2 Summit system has redundant (two) power supplies. You should connect a power cable to
each power supply, but both power supplies remain operational if only one cable is connected. The
power supplies can be accessed from the rear of the unit. You can remove and replace a power
supply while the K2 Summit system is operational. Each power supply has a fan with automatic
speed control and status LEDs that indicate current state and health. The power supply has protection
for over voltage, over current, and short circuits. The power supply modules plug into the midplane
board.

Codec module
The K2 Summit system has slots for two codec modules. Each codec module hosts two media
input/output channels. The codec modules are oriented horizontally across the rear of the K2 Summit
system chassis. They provide the majority of the K2 Summit system’s media-related input and
output connectors on the rear panel. The codec modules plug into the midplane board.
A codec module can host a codec option card. The codec option card provides extended functionality
to the channels hosted by the codec module.
