32 K2 Summit Production Client Service Manual 12 October 2009
Chapter 1 Product Description
When configured as RAID 1, you can remove and replace a disk module while the K2
Summit Client is operational.
Refer to “Disk module removal” on page 93 for procedures.
CompactFlash boot media
The CompactFlash boot media contains the system drive, also known as the C: drive.
The C: drive contains application and operating system files. The CompactFlash
media is hosted by the front interconnect board.
Refer to “CompactFlash boot media removal” on page 93 for procedures.
Power supply modules
The K2 Summit Client 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 Client is
operational. Each power supply has a fan with automatic speed control and status
LEDs that indicate current state and health. Refer to
“Power supply problems” on
page 82 for LED descriptions. The power supply has protection for over voltage, over
current, and short circuits. The power supply modules plug into the midplane board.
Refer to “Power supply module removal” on page 94 for procedures.
Codec module
The K2 Summit Client 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 Client chassis. They provide the majority of the K2 Summit
Client’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 pair of codec option cards. It is not allowed to have a codec
module host just one codec option card. There are two types of codec option cards, as
follows:
• MPEG-2 encoder card
• AVC-Intra codec card
A codec module that hosts codec option cards must have either two MPEG-2 encoder
cards or two AVC-Intra codec cards. It is not allowed to have one MPEG-2 encoder
card and one AVC-Intra codec card on the same codec module.
Refer to “Codec module removal” on page 94 for procedures.
MPEG-2 encoder card
A pair of MPEG-2 encoder cards is a codec module option. A codec module can host
two MPEG-2 encoder cards, one for each of the codec module’s channels. An
MPEG-2 encoder card provides MPEG-2 encode functionality to a channel. MPEG-2
decode functionality is a standard feature and does not require a dedicated card.
Refer to “Codec option card removal” on page 95 for procedures.
