Innovative FAST stacking design
Nortel’s innovative FAST (Flexible
Advanced Stacking Technology)
stacking design of the Ethernet Routing
Switch 5000 Series allows for simulta-
neous bidirectional traffic flow on each
stacking port (Figure 2). In a full stack,
this design yields up to 640 Gbps
stacking bandwidth.

This design supports an optimal data

flow across the stack using a shortest
path algorithm.
Most vendors today employ a tradi-
tional ring architecture, meaning that
a packet travels on the ring in only one
direction. For example, in a stack of
eight switches, if a packet needs to go
from unit 2 to unit 3, it can get there
in a single hop. But if a packet needs to
go from unit 3 to unit 2, then it has to
traverse from 3 to 4, 4 to 5, 5 to 6, and
so on until it reaches unit 2. This
requires seven hops.

Plug-and-play stacking with
built-in stacking ports
The Ethernet Routing Switch 5530 has
built-in stacking ports for faster, plug-
and-play stacking. This is more cost-
effective as cascade modules are not
required. This stacking design frees up
both of the uplink ports for dedicated
connectivity to the backbone or high-
speed servers. The Ethernet Routing
Switch 5530 is shipped with a cascade
cable (1.5 feet). In addition, cascade
cables are also available in different
lengths — 1.5 feet, 10 feet and 5
meters (16.4 feet) — to cover a variety
of stacking needs.

Recessed stacking connectors
for higher reliability
The Ethernet Routing Switch 5530
is designed with recessed stacking
connectors that save premium closet
space and protect the integrity of
the stack from accidental contact
(Figure 3).
