Product Information

Memory

Memory

The B2000 workstation has four slots for memory DIMMs. You can install only 128 MB, 256 MB, or 512 MB DIMMs in these slots. The minimum memory configuration for a B2000 workstation is 256 MB, and the maximum is 2 GB.

To install memory DIMMs, refer to “Replacing or Installing Additional Memory DIMMs” on page 115.

CAUTION If memory is installed improperly or is defective, the B2000 workstation’s operating system will not boot-up, and a DIMM error chassis code will appear in the LCD. If an error does occur, refer to Chapter 3, “Troubleshooting.”

Memory Failures

The HP VISUALIZE B2000 system (with HP-UX 10.20 and later) uses Memory Page Deallocation, a feature that allows the system to provide information to the operating system about memory failures.

You can use the memrpt command with the detail switch to obtain information about the Memory Page Deallocation Table (PDT) as well as single bit errors logged by the system, by typing the following:

# /usr/sbin/sysdiag Enter

DUI>logtool Enter

LOGTOOL>memrpt detail Enter

The PDT can also be checked using the pdt command in the Service menu of the Boot Console Handler (refer to Chapter 6). If you replace a defective DIMM, use the Service

Menu’s pdt clear command to clear out the PDT.
