About replacement power supplies
Replacement power supplies for the 90-240 VAC SYS and 90-240 VAC POE, are
functionally equivalent to the original power supplies, and can be used in
combination with the original power supplies in the same chassis. Although the
model numbers for both the newer and older versions of the power supplies are
identical, the front of the power supplies are visually different and the manufacturing
part numbers are different.
The following illustration shows a side-by-side comparison of the 90-240 VAC SYS
replacement power supply and the original power supply. The one on the left is the
replacement power supply and the one on the right is the original power supply.
Figure 13 shows a side-by-side comparison of 90-240 VAC SYS power supplies.
Figure 14 shows a side-by-side comparison of the 90-240 VAC POE replacement
power supply and the original power supply. The one on the left is the replacement
power supply and the one on the right is the original power supply.
