Forecast and Analysis report, the Power over Ethernet market revenue is expected to grow at an 8.9 percent CAGR (compound annual growth rate) over the next five years. 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’...
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.
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.
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.
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.
The switch can detect and report these issues without unplugging cables and plugging in expensive cable testers. (Feature supported with future software release.)
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).
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.
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.
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.
CLI commands. This editable ASCII configuration file can then be uploaded to a switch from an external file server. The ASCII configuration file contains configuration settings for the following network management applications: •...
