Management
An RJ45 serial console port on the rear panel of the 5520 Series switch enables you to connect a
terminal and perform local management. An Ethernet management port can be used to connect the
system to a out of band management network for administration. Alternatively, you can use an Ethernet
cable to connect this port directly to a laptop to view and locally manage the switch configuration. The
Ethernet management port supports 10/100/1000 Mbps speeds.
