Nortel BayStack 5520-24T-PWR User Manual

T
he way in which businesses use LANs is changing and the performance requirement at
the edge of the network is becoming more demanding. IP Telephony and other collabo-
rative applications are driving more traffic to the edge of the network. As file sizes continue to
grow, users need more bandwidth. Quite simply, the convergence of voice, video, data, and
storage enables users to do more from their desktop. Enterprises need to be able to address
today’s increased demands and still prepare for the unknown demands of tomorrow. By
re-assessing 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.
