As more Gigabit desktops are deployed,
the need for faster uplink is also
impacted, driving the need for multiple
Gigabits links trunked together or 10-
Gigabit technology. Enterprises need
to be able to address today’s increased
demands and still prepare for the
unknown demands of tomorrow. By
reassessing how they’re using the wiring
closet, they can achieve both goals, and
be assured that their investments will
be protected for a long time to come.
A new addition to the Nortel Ethernet
Routing Switch 5000 Series, the Nortel
Ethernet Routing Switch 5530-24TFD
is a next-generation stackable 10/100/
1000/10000 Mbps Ethernet Layer 3
routing switch designed to provide
high-density Gigabit desktop connec-
tivity and Gigabit and 10-Gigabit fiber
connectivity for aggregation for mid-
size and large enterprise customers’
wiring closets. The Ethernet Routing
Switch 5530 combines higher flexibility
of deployment using Gigabit copper
or fiber connections coupled with
exceptional performance utilizing
dual 10-Gigabit uplinks. The Ethernet
Routing Switch 5530 is a scalable and
resilient solution that provides excep-
tional security features and support for
enhanced convergence while minimizing
capital and operational expenses.
The Ethernet Routing Switch 5530-
24TFD provides 24 10/100/1000
BASE-T RJ-45 ports, 12 shared Small
Form-factor Pluggable (SFP) slots, and
2 slots for 10-Gigabit Ethernet Small
Form-factor Pluggable (XFP) modules.
The switch includes two built-in
stacking ports in a compact one rack-
unit high design. The Ethernet Routing
Switch 5530-24TFD may be utilized in
standalone mode, or may be stacked
together in a mixed stack of eight units
with existing Ethernet Routing Switch
5510-24T/48T or 5520-24T/48T-
PWR devices.
High-density Gigabit
desktop switching
The Ethernet Routing Switch 5530
provides up to 24 10/100/1000BASE-T
RJ-45 ports. As many as eight Ethernet
Routing Switch 5510, 5520 and 5530
models can be stacked to achieve up to
384 10/100/1000 ports for high-density
Gigabit desktop switching. The Ethernet
Routing Switch 5530 can also be used
for server aggregation.
High-density Gigabit
fiber switching
The Ethernet Routing Switch 5530
includes 12 SFP (Gigabit fiber) ports
that are shared with 12 10/100/1000
ports, making it an ideal solution for
aggregation of wiring closet switches.
Up to eight Ethernet Routing Switch
5530s models can be stacked to achieve
up to 96 SFP ports for high-density
Gigabit fiber connection. The Ethernet
Routing Switch 5530 can also be used
for server aggregation for servers with
fiber NICs. IEEE 802.3z-compliant
1000BASE-SX, 1000BASE-LX and
1000BASE-CWDM physical interface
support provides flexibility in switch
deployment.
Up to 16 10-Gigabit uplink
ports in a stack
The Ethernet Routing Switch 5530 has
dual built-in 10 Gigabit uplink ports
— ports 25 and 26 — for dedicated
uplink connectivity to network core
switches such as the Ethernet Routing
Switch 8600 (formerly known as
Passport 8600). Using the proven
Distributed Multi-Link Trunking
(DMLT) resiliency feature, up to 16
10-Gigabit XFP ports are available for
uplink connectivity in a full stack —
among the highest in the market.
The higher uplink performance opti-
mizes the Gigabit data traffic from
wiring closets to the network core
and improves business productivity.
The 10-Gigabit ports can also be used
for 10-Gigabit server connections.
IEEE 802.3ae-compliant 10GBASE-LR,
10GBASE-ER and 10GBASE-SR
interfaces are supported.
Switch fabric architecture
offering non-blocking wire-
speed performance
The Ethernet Routing Switch 5530 has
a high-performance Layer 3 switching
fabric with a maximum of 160 Gbps
forwarding bandwidth and wire-speed
performance.
Layer 3 IP routing
The Ethernet Routing Switch 5530
architecture supports wire-speed Layer
3 IP routing with static and local route
support. The Ethernet Routing Switch
5530 supports high-performance wire-
speed IP routing between VLANs. IP
routing with static routes at the edge
improves the network performance as
the packets do not have to go to the
core and the routing takes place within
the switch or stack.
The Ethernet Routing Switch 5530
supports the DHCP (Dynamic Host
Configuration Protocol) Relay feature
providing the system with the ability to
relay DHCP requests to the DHCP
server and eliminates the need for a
DHCP server on every subnet. It for-
wards a request for an IP address from a
client to a DHCP server across subnets.
Software feature enhancements are
planned to include support for routing
protocols such as Routing Information
Protocol (RIP v1/v2), OSPF and VRRP.
