Chapter 1 Product Description
SCSI backplane
A K2 Media Client must provide connections for RAID drives to support hot-swap
functionality. On internal storage models, both system and media drives require
connections. On external storage models, only the two system drives require
connections. Therefore, backplane configuration varies, as follows:
• Some external storage K2 Media Client have no SCSI backplane. Instead, RAID
drive connections are provided by two SATA drive connector boards.
• Other K2 Media Clients have a SCSI backplane and a SCSI controller adapter.
These K2 Media Client can be either internal storage or external storage. On these
K2 Media Clients the SCSI backplane provides the connection for each RAID
drive. It is mounted in the center of the unit.
Refer to “SCSI backplane removal” on page 129 for procedures.
CPU motherboard
The K2 Media Client uses an extended ATX motherboard with an Intel Xeon
processor. The motherboard provides PCI board slots, built in Gigabit Ethernet, and
USB ports. The Type I motherboard provides USB 1.1 ports. The Type II and Type
III motherboard provides USB 2.0 ports. It is located in the bottom rear of the K2
Media Client chassis.
Refer to “CPU motherboard replacement” on page 140 for procedures.
