Cabling

Table 6 contains the cabling specifications for the twisted pair ports.

Note

The twisted pair ports on the switch feature auto-MDI when 
operating at 10 or 100 Mbps. Each port is individually configured as 
MDI or MDI-X when connected to an end node. Consequently, you 
can use either a straight-through or crossover twisted pair cable 
when connecting any network device to a twisted pair port on the 
switch.
