Installing the 9Cx14 Chassis

Redundant Power Supply Modules

The 9C114 and 9C714 support the installation of two power supplies for power
supply redundancy and load sharing. If a 9C500 Power Box is used, up to six
power supplies may be installed.

9C300-1 Environmental Module

The 9C300-1 Environmental Module provides out-of-band management
capabilities, monitors power supply and environmental status, and has a built-in
cooling system. The 9C300-1 Environmental Module is also "hot swappable" so
that it can be removed for repair or replacement without causing network
downtime. For details refer to the SmartSwitch 9000 9C300-1 Environmental Module
User's Guide .

The Backplane

The 9C114 SmartSwitch 9000 provides six distinct backplane buses, and the 9C714
provides an additional seventh bus, the Cell Transfer Matrix. Each bus serves a
particular set of needs. The seven backplane buses are shown in Figure 1-1.
