Minimum Requirements
for Normal Operation
The following minimum components are required for normal operation of the
Switch 4005:
■
Two fan trays (four fans total)
■
One 300 Watt AC power supply
■
One Switch Fabric Management Module (SFMM) operating with system
software
■
The number and type of interface modules that are appropriate for your
network connectivity needs
■
Blank faceplates that cover all empty module slots and the second power
supply bay (if a second power supply is not installed).
Module Slots in the
Chassis
You insert modules vertically into the chassis slots so that the slot number shows
through a hole in the module faceplate. As shown in Figure 1, the slots for
interface modules are numbered from left to right, starting with number 1 and
continuing to 12. The two center slots are numbered M1 and M2 because they
exist solely to contain Switch Fabric Management Modules (SFMMs). An SFMM
can be placed in either of these slots.
