Multi-Link Trunking
Multi-Link Trunking (MLT) enables group-
ing of links between the BayStack 5510 and
another switch or server to provide greater
bandwidth with active redundant links.
Nortel Networks unique Distributed Multi-
Link Trunking (DMLT) feature allows
trunked ports to span multiple units of the
stack for fail-safe connectivity to mission-
critical servers and the network center (Figure
4). BayStack 5510 Switches have been archi-
tected to support up to 32 trunks per switch
or stack, with each trunk consisting of up to
eight members per trunk. Each trunk can
provide bandwidth of up to 16 Gbps.

The Split Multi-Link Trunking (SMLT)
feature of Passport 8600 eliminates single
points of failure in the network and allows
wiring closet switches, such as the BayStack
5510, to have multiple active connections
to the network core (Figure 5). All links from
a distributed multi-link trunk can be active
simultaneously. This allows customers to
load-balance their network, double the band-
width, and use all the ports they have paid for.

By combining the reliability of the Passport
8600 with the BayStack 5510’s resilient
trunking features—including DMLT, MLT,
and bi-directional FAST stacking, Nortel
Networks has created the next generation of
flexible networking solutions. BayStack 5510
Switches are architected to support SMLT
and Inter Switch Trunk (IST) in the future.

Integrated Time Domain Reflectometer (TDR)
†
For advanced resiliency, the BayStack 5510 is architected to include an integrated TDR. This
feature will simplify troubleshooting of the physical cable plant, enabling IT managers to
quickly identify the failing mechanism and isolate to the source of the problem, helping
ensure maximum uptime of the network. Through remote and non-invasive diagnosis of
cabling issues such as cable opens, cable shorts or impedance mismatch in the cable and
report, within one meter, the distance of the fault. The switch can detect and report these
issues without unplugging cables and plugging in expensive cable testers. (Feature supported
with future software release.)

Redundant power and UPS support
With connectivity to the BayStack 10 Power Supply Unit (PSU) paired with a –48V DC-to-
DC converter module, BayStack 5510 Switches deliver redundant power supply (RPS)
support crucial in mission-critical environments. Nortel Networks 800-watt BayStack 10
Power Supply Unit allows up to four failed network devices to simultaneously receive RPS
support. In addition to the RPSU support, Uninterruptible Power Supply (UPS) capability is
provided cost-effectively in the same BayStack 10 chassis.
