Cabletron Systems 9000, 9C114 manual Flexible Network Bus

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.
