The redundant power supply modules used by the ZX-250r provide voltage auto-sensing for either 115 or 230 volts
AC. The modules are also hot swappable. The ZX-250r can be run with either one or two power supply modules
installed. Using both power supply modules with the ZX-250r provides redundancy for enterprise backbone use.
Figure B-2 shows the details of a ZX-250r power supply module.
