Ethernet Switch
This quick start guide describes how to install and use the hardened Ethernet Switch. Capable of operating at temperature extremes of -10°C to
+60°C, this is the switch of choice for harsh environments constrained by space.
Physical Description
The Terminal Block and Power inputs
DC Terminal Block Power Inputs: There are two pairs of power inputs can be used to power up this Industrial Ethernet Switch. Redundant power
supplies function is supported. You only need to have one power input connected to run the Switch.

Mini-GBIC combo port:
8 auto-detect Giga port—UTP or fiber. The gigabit Ethernet ports are hared with the mini-GBIC ports. UTP (Gigabit Ethernet) ports can
operate in half/full-duplex modes and work at speeds of 10/100/1000Mbps that support auto-sensing technology to enable each port to detect
the connecting speed. The mini-GBIC port is a joint for a mini-GBIC (SFP) transceiver, the switch can be connected through fiber to another
one.
Use four twisted-pair, Category 5e or above cabling for RJ-45 port connection. The cable between the switch and the link partner (switch,
hub, workstation, etc.) must be less than 100 meters (328 ft.) long.
Use the mini-GBIC ports to uplink to another switch by inserting the mini-GBIC (SFP) transceiver.

Connecting to the Console Port
The supplied cable which one end is RS-232 connector and the other end is RJ-45 connector. Attach the end of RS-232 connector to PC or
terminal and the other end of RJ-45 connector to the console port of the switch. The connected terminal or PC must support the terminal
emulation program.
