4.2 Application in a Small/Medium-Sized Enterprise Network
Typically, an S7500 series switch can be used at the backbone layer in a
small/medium-sized enterprise network. The switch is connected to its neighboring
devices as follows: In the downstream direction, the switch is connected to the Layer
2/3 Ethernet switches (for example, H3C S3100/S3600 series switches) of workgroups
or directly connected to user's workstations through GE/FE optical or electrical ports; it
is connected to other floors/buildings through GE optical ports (long- or short-haul) or
multi-GE Trunks; and it is connected to server groups through GE/FE electrical ports. In
the upstream direction, it is connected to a router through a 10/100 Mbps electrical port.

4.3 Application in a Large-Sized Campus Network
Typically, an S7500 series can be used at the aggregation or backbone layer in a
large-sized campus network. In this case, it is often deployed in cabling room or center
office. In the downstream direction, the switch is connected to the
workgroup/campus-level Layer 2/3 Ethernet switches (H3C S3100/S3600 series
switches) through GE/FE optical or electrical ports. In the upstream direction, it is
connected to a backbone Ethernet switch or a router through a GE optical/electrical
port.
