Six Fiber Optic
1000 Mbps Ports
(AT-9006SX/SC
and
AT-9006LX/SC)
The AT-9006SX/SC and AT-9006LX/SC Gigabit Ethernet Switches feature
six fiber optic ports with dual SC connectors. The ports operate at 1000
Mbps in full-duplex mode. (The ports can be configured as half-duplex,
but since all 1000 Mbps network devices operate at full-duplex, there
should be no reason to set one of the ports to half-duplex.)
Each port on the AT-9006SX/SC Switch has a maximum operating
distance of 550 meters using multimode fiber optic cabling. The ports on
the AT-9006LX/SC offer a maximum operating distance of 550 m using
multimode cabling or 2 km using single-mode fiber optic cabling.
RS232 Connector
The RS232, DB-9 female connector provides out-of-band local
management for the switch. You can use either a VT100 terminal or a
personal computer with a terminal emulation program to connect to the
RS232 port. The connector uses a straight-through cable.
System and Port
LEDs
The switch features a series of system and port LEDs that you can use to
monitor and troubleshoot the switch. Table 2 describes the system LEDs.
