Auto-crossover Ethernet Ports
All ports are auto-crossover, that is auto-MDIX ports (Media Dependent
Interface Crossover), so you may use either a straight-through Ethernet
cable or crossover Ethernet cable for all Ethernet port connections. Auto-
crossover ports automatically sense whether they need to function as
crossover or straight ports, so crossover cables can connect both
computers and switches/hubs.
Refer to the Product Specifications section for the types of network cable
used for the different connection speeds.
Front Panel LEDs
The LEDs on the front panel indicate the real-time status of the switch.
