K2 Lx0 RAID features The K2 Lx0 RAID is a high performance, high availability mass storage system used in K2 Lx0 and K2 Lx0 Expansion K2 Storage Systems. The K2 Lx0 chassis 4 Gb/s host interface supports industry-standard technology. FLT CLR...
The K2 Lx0 RAID Expansion Chassis provides additional storage capacity. It contains: • Two Expansion Adapters • Up to eleven K2 Lx0 RAID Expansion Chassis can be connected to a single K2 Lx0 RAID chassis • A single disk-array storage system with up to 144 drives...
Power Supply 0 Controller 0 (or Expansion Adapter 0) NOTE: Every K2 Lx0 RAID chassis controller includes a backup battery so that if electrical power is lost, data stored in cache memory will be saved. Chassis The chassis is a sheet-metal housing that contains chassis slots for the RAID controllers or expansion adapters, disk drives, power supplies, and the LAN card.
SAS Connector The expansion adapter in the K2 Lx0 Expansion has two SAS ports: DP-IN and DP-OUT. SAS cabling connects the DP-IN port to a K2 Lx0. There are two port status LEDs for each SAS port. Refer to “Interpreting expansion adapter status LEDs” on...
The power supplies are designed so as to protect the disk drives if you install them while the K2 Lx0 External RAID is powered up. A disk with power-related faults will not adversely affect the operation of any other disk.
“Environmental limits” on page Cabling requirements It is recommended that you use the cables shipped with your K2 Lx0 RAID when making connections. For cable specifications, refer to “Cable lengths” on page Host cables must meet the appropriate 4-Gbit HPA compliance standards.
Chapter 2 K2 Lx0 RAID Installation Information Binding disk modules into groups After cabling a K2 Lx0 RAID and any K2 Lx0 Expansion Chassis, you must bind disk modules using the Storage Utility provided by Grass Valley. Once bound, the order of the drives is important.

To install the K2 Lx0 RAID rack mounts: 1. Remove the rack brackets from the guide brackets at both ends of the rail. Save the rack brackets and the M3 screws, as they are used later in this procedure.
8. Firmly tighten the rail adjustment screws. 9. Repeat this procedure for the other side rail. Inserting the K2 Lx0 RAID chassis in the rack 1. Rest the chassis on the support angles shown. Slide the chassis back and into place 2.

WARNING: Make sure the power cords meet local safety and electrical standards. CAUTION: The K2 Lx0 RAID system must be electrically grounded. Operating the system without proper grounding can damage disk drives. If the outlet you use is not grounded, make sure that a licensed electrician replaces it and installs a grounding conductor.
K2 Lx0 RAID power-down NOTE: If your K2 Lx0 RAID system is part of a shared storage system, refer to the K2 Storage System Instruction Manual for instructions on shutting down the shared storage before powering down a K2 Lx0 RAID.

The SNMP agent software required for NetCentral monitoring resides on the RAID storage device itself. As a result, the K2 Lx0 External RAID appears in NetCentral as a standalone device rather than as a subsystem of the K2 Media Client.
Chapter 3 Servicing the K2 Lx0 RAID Communication with NetCentral takes place over the Ethernet connection on each RAID controller. To monitor the K2 Lx0 External RAID, you must connect network cabling, power on the system, then configure network and SNMP settings as described in the K2 Storage System Instruction Manual.

Chapter 3 Servicing the K2 Lx0 RAID • The RAID chassis configuration information is written to the first three disk modules. If all of these disk modules are replaced with new devices with the power supplies turned off, the information is lost. This condition is indicated by the SERVICE LED blinking at a high rate at chassis power up.
• Wait at least three minutes after removing the previous disk module. • Put a location label on the replacement disk drive, as appropriate for the slot into which it is installed. July 31, 2008 K2 Lx0 RAID Instruction Manual...

Chapter 3 Servicing the K2 Lx0 RAID To install a disk module: 1. Open the lever of the disk module, as demonstrated in “Removing a disk module” on page 2. Insert the drive in the unit. 3. Insert the drive as shown in the following diagram.
3. Remove the power cable and the controller cable connected to the module. Note where the cables connect to the module. The SAS cables for the K2 Lx0 Expansion Chassis are keyed so that one end can only be used with the DP-IN connector and the other end can only be used with the DP-OUT connector.
• Use power cables that are shipped with the RAID unit. • The K2 Lx0 RAID and K2 Lx0 Expansion Chassis have dual power supply configurations so that they do not halt if one power supply breaks down. Even if a...
