Cascade Down connector
Use the Cascade Down connector to connect a switch to the next unit in the
stack through a cascade cable. Connect the other end of the Cascade Down
cable to the Cascade Up connector of the next switch in the stack. A return
cable from the Cascade Down connector of another unit to the Cascade Up
connector of the first unit completes the stack connection (see
stacking diagram" (page 45)"Connecting cascade cables" (page 46)
).
Note: To create a stack connection, order the appropriate Nortel
Ethernet Routing Switch 4500 Series cascade cables to ensure fail-safe
stacking. A 1.5 foot stacking cable is included with the switch. For
stacking three or more units (maximum 8 units per stack), order the 5’,
10’, 14’ or 16.4’ cables as applicable.
Cascade Up connector
The Cascade Up connector provides an attachment point that accepts a
cascade cable connection from another unit in the stack. A return cable from
the Cascade Down connector of one switch to the Cascade Up connector
of an adjacent switch completes the stack connection. See
and
"Connecting cascade cables" (page 46)
"Simplified stacking diagram" (page 45)
illustrates a simple, two-switch
stack connection.
