Draft Document for Review November 15, 2007 3:27 pm 4372ch05.fm
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.
Figure 5-29 List of POS systems
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).
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.
