Rear ports and stacking
The rear panel view of a Nortel Ethernet Routing Switch 2500 series
switch consists of two RJ-45 1000BaseT ports and a Unit Select switch. In
Stacking Mode, the two rear ports become the Cascade Down and Cascade
Up ports for connecting switch units in a stack configuration. The rear panel
components are illustrated in the following diagram:

Unit Select switch
The Unit Select switch is used to designate a switch in the stack as the
base unit. Sliding the switch to the right designates that switch as the base
unit. Only one switch in a stack has the Unit Select switch in the base unit
position. All other switches in the stack must have the Unit Select switch in
the left position.
The base unit designation of a switch is also displayed on the front panel
LED display. For more information, see Table 2 "Ethernet Routing Switch
2500 Series LED descriptions" (page 28)
