IBM REDP-4372-00 manual List of POS systems

Draft Document for Review November 15, 2007 3:27 pm 4372ch05.fm

Attention: It is important to emphasize that when performing a hardware switch the replacement unit must be exactly the same model and configuration as the machine it is replacing.

In our lab environment we used the hardware switch function to replace POS01 with POS02. Unfortunately, we did not have two machines of exactly the same model available to us and therefore, once the switch and restore had been completed, the newly configured POS01 (formerly POS02) would not boot the operating system sucessfully. This should serve to emphasize the warning above.

Note that in the POS list, the machine with the serial number: 41W8197, has the name POS01 (Figure 5-29). This is the original POS01 which we have taken several backups against. The machine with serial number: 41A2041, is labeled “POS02” and will become the new POS01.

We performed the following steps on our production server (NICE) to accomplish a hardware replacement of POS01 with POS02:

1.Boot the replacement terminal (POS02) into PXE mode.

2.Right-click the the entry for POS01 in the POS terminal list, and select “Hardware Switch” from the context menu (Figure 5-30).
