Communication Connections
IE-SW-BL05(T)-4GT-1GS switches have 2 types of communication port:
• 4 x 10/100/1000BaseT(X) Ethernet ports
• 1 x Combo-port, usable as 10/100/1000T(X) or 100/1000BaseSFP
port
10/100/1000BaseT(X) Ethernet Port Connection
The 10/100/1000BaseT(X) ports located on switch’s front panel are used
to connect to Ethernet-enabled devices. Most users will choose to
configure these ports for Auto MDI/MDI-X mode, in which case the port’s
pinouts are adjusted automatically depending on the type of Ethernet
cable used (straight-through or cross-over), and the type of device
(NIC-type or HUB/Switch-type) connected to the port.
In what follows, we give pinouts for both MDI (NIC-type) ports and
MDI-X (HUB/Switch-type) ports. We also give cable wiring diagrams for
straight-through and cross-over Ethernet cables.
