3 Installing LH 4 Components

WARNING Do not use memory or VRMs from the LH 3/LH 3r CPU baseboard with the LH 4/LH 4r CPU baseboard. This may result in damage to components and put data integrity at risk.

Upgrading the HP NetServer LH 3/LH 3r to an HP NetServer LH 4/LH 4r requires several steps, but there are few differences between the two NetServers.

Remove any packing materials and position the following components where you can reach them from your work position.

CPU Baseboard Components

The LH 3/LH 3r has a CPU baseboard that accepts two Intel Pentium II™ Xeon™ processors, each with an associated Pentium II Voltage Regulator Module (VRM). The LH 4/LH 4r has a new CPU baseboard that accepts up to four Intel Pentium II Xeon processors and six new VRMs designed especially for the Intel Pentium II Xeon processors.

Figure 3-1 shows the CPU baseboard as it looks after unpacking.
