1.2.2
M4-POWER power unit chassis
The M4-POWER power unit chassis enables redundant power supply. It has
three slots for plug-in power units. The plug-in power units can be replaced
during operation (hot-swappable).
Depending on the plug-in power units connected, you can use an M4-POW-
ER power unit chassis to implement the redundant power supply for several
MACH 4000 devices.
You connect the M4-POWER power units to the M4-POWER connection
on the back of the MACH 4000 device using the power supply cable sup-
plied with the M4-P-xx plug-in power units.
