Using the 5300 Series on the Edge When your network expands and the users need to access resources beyond the edge of the local network, the Switch 5300xl Series are excellent platforms for that expansion. With the flexibility of 4 or 8 slots, the high port count 10/ 100-TX xl Module for local connections, and the availability of Gigabit speeds through either the Gigabit Transceiver xl Module or the 100/1000-T xl Module, the Switch 5300xl Series can provide that access beyond the edge for a high number of network users. In the above illustration, two Switch 5308xls are connected to a ProCurve Routing Switch 9308, which can serve as a campus backbone or core switch. The 1000 Mbps fiber-optic connections between the two Switch 5308xls and the Routing Switch 9308 is by way of Gigabit-LX mini-GBICs installed in mini-GBIC xl Modules in the Switch 5308xls and Gigabit-LX ports on the Routing Switch 9308. With the Gigabit-LX connections, the distance between the Switch 5308xls and the Routing Switch 9308 can be up to ten kilometers. The connections are trunked, through a configuration change on the Switch 5308xl, to provide redundancy and load sharing for higher bandwidth. 2-23
