BayStack 5520 Switch benefits
• Power to IP phones, wireless access points, network cameras, security and lighting devices,
and access control devices
• Provides power on all ports
• IEEE 802.3af compliant to power multiple vendors' equipment
• Enables data and power to be transmitted over a single cable without using power outlets
• Automatically provides power to a detected device
• Up to 384 ports of Gigabit desktop connectivity in an 8-rack unit high design—the highest
density in the industry
• Industry-leading Gigabit Ethernet performance with innovative stacking using FAST stack
(Flexible Advanced Stacking Technology)—providing up to 640 Gbps
• High-performance switch fabric of 160 Gbps assures wire-speed operation with no packet loss
• Hardware-based Layer 3 routing at wire-speed and across the stack
• Intelligence at the network edge with Quality of Service (QoS)
• Cost-effective plug-and-play stacking with built-in stacking ports
• Up to 32 built-in SFP GBIC uplink ports in a stack
• Flexible stacking across all BayStack 5000 series switches—a stack is managed as a single
entity with a single IP address
• Unmatched resilient connectivity and stackability for minimal network downtime
• Secure access and data traffic protection
• All BayStack switches come with a lifetime warranty
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.

Part of Nortel Networks BayStack 5000 Series, BayStack 5520 Switches are one rack unit high stackable 10/100/1000 Mbps Ethernet Layer 3 routing switches designed to provide high-density Gigabit desktop connectivity and Power over Ethernet capability to mid-size and large enterprise customers’...
- Page 3 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. To configure IP routing on the BayStack 5520 Switches or stack, you must use virtual LANs (VLANs) to create IP interfaces.
- Page 4 BoSS simplifies network operations by reducing the number of steps required for switch software updates. With BoSS, only a single image needs to be downloaded from Nortel Networks support site for all BayStack 5000 Switch types. Loading the image to different switches is also considerably simplified.

Page 5: Default Ip Address
With this feature, synchronization of the switch or stack’s clock to the real-time clock on the SNTP server is allowed. If the system (switch or stack) uses SNTP, then SNTP time is used to time-stamp system log (Syslog) messages. If SNTP is not in use, then the system uses a time-stamp relative to boot time. -
Page 6: Web Quick Start
With the Guest VLAN feature, if a user connects to a BayStack 5520 switch port and is not recognized to be authenticated on that port, that user will be placed into a Guest VLAN with the settings as defined by the administrator. - Page 7 The switch can detect and report these issues without unplugging cables and plugging in expensive cable testers. (Feature supported with future software release.)
- Page 8 15.4 W per port from the BayStack 5520-24T-PWR Switch. Without BayStack 15 PSU, the BayStack 5520-24T-PWR Switch would supply an average of 13 W per port (ports can exceed 13 W per port as long as the total of all ports requiring power does not exceed 320 W). A DC cable connector cable is required to connect from a BayStack 5520 Switch to the BayStack 15 RPSU module (see ordering information section for order numbers).
- Page 9 By classifying the traffic and placing it into an NNSC, complex QoS configurations are elim- inated. NNSC simplifies the deployment of a QoS-enabled network with Nortel Networks switching solutions, using a Web-based interface. This not only saves on provisioning time but most importantly, ensures that the QoS functions are provisioned consistently across the network.

Page 10: Traffic Policing
Traffic policing enables provisioning of different levels of service by limiting traffic through- put at the ingress (incoming) port of the BayStack 5520 Switch. For example, if a port is set to a certain speed, such as 10 Mbps, all traffic under 10 Mbps on that port will pass, and traffic that exceeds 10 Mbps on that same port is dropped. - Page 11 5520 Switches can stack up to eight units with a cascade stacking design, assuring continuous uptime even if a single switch in the stack should fail. A loop-back or cascade cable is used to seamlessly connect the entire stack to provide no single point of failure.
