INSTALLING THE SWITCH

The SmartCell 6A000 is hot swappable, meaning that you can install and remove it without turning off or unplugging
the SmartSwitch 6000 chassis. You can install as many as five switch modules in each chassis (using the 6C205-3
power supply). In this configuration, the SmartCell 6A000 modules provide up to 75 user ports. Modules should be
connected with inter-module trunks if traffic must cross between modules. Table 2-3 shows the maximum number of
LAN and ATM switch modules that can be installed in a SmartSwitch 6000 chassis.
