If it is not possible to use an isolated DC-DC power supply, then all interconnected devices must be bonded to a
common earth ground with all connection points within the same building. See the Install Guide.
Ethernet Interface Connection
(RJ45 Ethernet):
The switch has RJ45 and optical (mini-GBIC) electrical interfaces.
To connect the switch to a PC use a straight-thru or a crossover Ethernet cable. Connect the switch to an Ethernet
device with UTP or STP Ethernet cables.
Ethernet Interface Connection
(Fiber, SFP):
For a 100 Mbps fiber port, prepare the LC connectors or SC
connectors (using an optional SC-to-LC adapter). For the 1000 Mbps fiber ports, use mini-GBIC SFPs. These accept
plug in fiber transceivers that typically have an LC style connector, with MM, SM, long-haul or special-application
transceivers.
Warning
: Do not view optical connectors.
Console Connection
:
is for local management by using a terminal emulator or a computer with terminal emulation
software. Setup: DB9 connector connect to computer COM port. Baud rate: 115200bps. 8 Data bits, 1 Stop bit.
Priority: None. Flow control: None. To connect the host PC to the desired console port, use a male RJ45 connector-
to-RS232 DB9 (female) connector cable. Connect the RJ45 connector of the cable to the Console port of the switch.
Connect the DB9 connector of the cable to the PC COM port.
Power Connection
Warning
: Connect the power supply to the switch first while powered off, and then connect the
power supply to power.
Power Supplies
:
Various power supply models are available from Lantronix.
Warning
: Use an isolated power
supply in order for Lantronix to honor the switch warranty. Available Lantronix power supplies: PS 25105 and PS
25104. See the Install Guide.
Connecting Power
:
Switch input is 48 - 54VDC or negative 48 - 54VDC. To get full PoE output and meet the IEEE
802.3at standard, the input range must be 52-54VDC or negative 52-54VDC. Insert the positive and negative wires
into the
+
and
-
contacts on the terminal block and tighten the wireclamp screws. See the Install Guide.
Initial Switch Config via Web Browser
:
Initially reconfigure your PC IP address / subnet mask for the PC to
communicate with the switch. After changing PCs IP address, access the Web UI of the switch using the switch
default IP address. The factory default Username and Password are both
admin
. On first switch power up, a First
Time Wizard displays. See the
Web User Guide
.
Initial Switch Config via CLI
:
Access the Command Line Interface via telnet or SSH. See the
CLI Referenc
e.
