Installing LH 4 Components

10.Replace the boards in the memory cage. Lower the ejection levers to lock the board into place in the cage.

11.Close the cover of the memory cage.

Additional Processor, VRM, and Memory Configurations

The LH 4/LH 4r CPU baseboard is shipped with two processors, two terminators, and four VRMs. If you are installing additional processors at this time, refer to the processor upgrade kit documentation and install them, and install the new VRMs as well.

The LH 4/LH 4r CPU baseboard contains two 64 MB DIMM modules. If you are installing additional memory at this time, refer to the memory upgrade kit documentation and install it with the other DIMMs.

Installing the Chassis Reinforcement Bars

The chassis reinforcement bars are two metal bars that help hold the CPU baseboard in place in the LH 4/LH 4r chassis. Since the CPU baseboard fits into to small slots on the lower chassis reinforcement bar, you need to install these bars before installing the CPU baseboard.

Insert the chassis reinforcement bars next to the CPU baseboard, as shown in Figure 3-8. There are four Torx thumbscrews that secure the two bars to the chassis, and two Torx thumbscrews that connect the CPU baseboard to the top chassis reinforcement bar.

NOTE

If you are installing the chassis reinforcement bars while the

 

LH 4r is in the rack, you must install them from underneath.
