Power Connector - Allied Telesis AT-GS920/16 Installation And User Manual

Power Connector

MDI/MDI-X
The default configuration for all of the twisted pair ports on the switch is
auto-MDI/MDI-X where the ports automatically configure themselves as
MDI or MDI-X when connected to an end-node. Auto-MDI/MDI-X is in
effect when the ports are configured for Auto-Negotiation or 1000M/FULL.
In this mode, you can use a straight-through twisted pair cable to connect
any network device to a port.
Note
See "Ethernet Port Configuration" on page 84 for the port
configuration procedures.
You can manually force the highest numbered port to fixed MDI by using
one of the front panel push buttons. When all of the ports are configured at
once, then the configuration for all other ports is fixed MDI-X.
When a port is manually configured for a speed of 10M or 100M, then that
port is also configured for fixed MDI-X except in the case of the highest
numbered port, which is set to fixed MDI.
