MACH 4002
Release
1.0
10/05
The device conforms to the specifications of the standards
ISO/IEC 8802-3u 100BASE-TX/-1000BASE-T,
ISO/IEC 8802-3 100BASE-FX and
ISO/IEC 8802-3 1000BASE-SX/LX.
1.2 Voltage supply
On the back of the device there is a slot for a power supply unit (AC or DC)
and two inputs for the redundant power supply via the M4-POWER power
unit chassis.
1.2.1 Power supply on back of device
U Slide-in power units for MACH 4002 switch chassis
D M4-S-AC/DC 300W
D M4-S-24VDC 300W, 2 inputs for redundant power supply
D M4-S-48VDC 300W, 2 inputs for redundant power supply
See “Order numbers/Product name” on page 37
Note: The slide-in power units of the power unit chassis cannot be used for
the switch chassis.
1.2.2 M4-POWER power unit chassis
The M4-POWER power unit chassis enables redundant power supply. It has
three slots for slide-in power units. The slide-in power units can be replaced
during operation (hot-swapable).
Depending on the slide-in power units connected, you can use an M4-POWER
power unit chassis to realize the redundant power supply for several
MACH 4002 devices.
