AVC-Intra codec card
AVC-Intra codec card
A pair of AVC-Intra codec cards is a codec module option. A codec module can host
two AVC-Intra codec cards, one for each of the codec module’s channels. An
AVC-Intra codec card provides AVC-Intra encode and decode functionality to a
channel.
Refer to “Codec option card removal” on page 95 for procedures.
Disk controller board
The disk controller board provides the RAID functionality for the internal disks. It is
mounted horizontally in the front center of the unit. The disk controller board plugs
into the disk backplane board and the midplane board. K2 Summit Clients with
direct-connect storage or shared SAN storage do not contain a disk controller board,
as RAID disks are in the external RAID storage devices.
Refer to “Disk controller board removal” on page 101 for procedures.
Front interconnect board
The front interconnect board monitors and reports the status of the RAID drives, the
chassis fans, and the power supplies. It controls the individual RAID status LEDs and
the front bezel Power and Service LEDs. It hosts the CompactFlash boot media. It is
mounted horizontally in the center front of the unit. The front interconnect board
plugs into the midplane board.
Refer to “Front interconnect board removal” on page 100 for procedures.
Disk backplane unit
The disk backplane unit includes the disk backplane board and its mounting brackets.
The disk backplane board provides the connections for the disk modules and hosts the
disk status LEDs. It is mounted in the front center of the chassis. It plugs into the disk
controller board and the midplane board. A power cable connects the midplane board
and the disk backplane board. K2 Summit Clients with direct-connect storage or
shared SAN storage do not contain a disk backplane board, as RAID disks are in the
external RAID storage devices.
Refer to “Disk backplane unit removal” on page 99 for procedures.
Midplane board
The midplane board provides connections for the rear modules. The disk controller
board and the front interconnect board also plug into the midplane board. It is
mounted in the center of the unit. A power cable connects the midplane board and the
disk backplane board, if present.
Refer to “Midplane board removal” on page 102 for procedures.
Carrier module
The carrier module provides the functionality typically associated with a motherboard
in a PC. It hosts the CPU, one optional PCIe board, and provides rear panel
connections for Gigabit Ethernet, USB, VGA, and IEEE 1394a (Firewire). The IEEE
