SI305 – SI306 Industrial Gigabit PoE Ethernet Switch
Quick Installation Guide
Overview
The lite/unmanaged (PoE) Industrial Gigabit Ethernet Switch solutions are designed for supporting
standard industrial applications without complex setup to make the network truly plug-and-play.
Please verify that the box contains the following items :
Xentino Industrial Ethernet Switch
M4 Screws (for the wall mount plates & DIN CLIP)
Safety Instructions
When a connector is removed during installation, testing, or servicing, or when an energized fiber is
broken, a risk of ocular exposure to optical energy that may be potentially hazardous occurs, depending
on the laser output power.
The primary hazards of exposure to laser radiation from an optical-fiber communication system are:
Damage to the eye by accidental exposure to a beam emitted by a laser source.
Damage to the eye from viewing a connector attached to a broken fiber or an energized fiber.

Ethernet Interface Connecting (RJ45 Ethernet)
The switches provide two types of electrical (RJ45) and optical (mini-GBIC) interfaces.
Connecting the Ethernet interface via RJ45:
To connect to a PC, use a straight-through or a cross-over Ethernet cable,
To connect the Xentino SI Series switch to an Ethernet device, use UTP (Unshielded Twisted Pair) or
STP (Shielded Twisted Pair) Ethernet cables.
The pin assignment of RJ-45 connector is shown in the following figure and table.
Xentino SI Series switch must be properly grounded for optimum system
performance.

Quick Installation Guide
Never attempt to view optical connectors that might be emitting laser energy.
Do not power up the laser product without connecting the laser to the optical
fiber and putting the cover in position, as laser outputs will emit infrared laser
light at this point.
1. The DC power should be connected to a well-fused power supply.
2. Input power should be within the range of 54~58VDC for PoE+ compliant, or 4858VDC for PoE compliant.

Ethernet Interface Connecting the (Fiber, SFP)
For a 100 Mbps fiber port available, please prepare the LC connectors or SC connectors (with the use of
an optional SC-to-LC adapter). They are also available with multimode, single mode, long-haul (for
connections up to 120+ km) or special-application transceivers.
For a 1000 Mbps fiber port available, please use the mini-GBIC SFP (small form pluggable). These
accept plug in fiber transceivers that typically have an LC style connector. They are available with
multimode, single mode, long-haul (for connections up to 80+ km) or special-application transceivers.
For each fiber port there is a transmit (TX) and receive (RX) signal. Please make sure that the transmit
(TX) port of the switch connects to the receive (RX) port of the other device, and the receive (RX) port of
the switch connects to the transmit (TX) port of the other device when making your fiber optic
connections.
Power Connecting
The switch can be powered from two power supply (input range 12V – 58V). Insert the positive and
negative wires into V+ and V- contact on the terminal block and tighten the wire-clamp screws to prevent
the wires from being loosened.
