1. Introduction
All Antaira industrial managed switches come with a pre-installed “user-friendly” web console interface,
which allows users to easily configure and manage the units, whether one is using a serial console and
command line interface(CLI) commands like Telnet, SSH, HTTP (Web GUI) or simple network management
protocols (SNMP).
1.1 Product Overview
Antaira Technologies’ LNP-2804GN-SFP-T is a 28-port industrial Gigabit PoE+ managed Ethernet switch
embedded with 24*10/100/1000Tx Ethernet ports that support IEEE802.3at/af for a maximum of 30W/port
and 4*100/1000 SFP slots for combo RJ45/Fiber connections. The LNP-2804GN-SFP-T is a fully
manageable Layer 2 Ethernet switch that is pre-loaded with a user-friendly web management console
design. It supports the ring network redundancy function using X-Ring (ultra-high-speed recovery time < 20
ms), RSTP/STP (802.1w/1D), MSTP. The advanced network filtering and security functions, such as IGMP,
VLAN, QoS, SNMP, port lock, RMON, and 802.1X/HTTPS/SSH/SSL increase determinism and improve
network management for remote SCADA systems or control networks.
The LNP-2804GN-SFP-T is IP30 rated and rack mount design with extended temperature range (EOT: -
40°C to 75°C). It also provides high EFT and ESD protection for industrial networking applications, such as
power/utility, water wastewater, oil/gas/mining, factory automation, security surveillance, ITS and any other
outdoor or harsh environment applications.

2.6 Ethernet Ports
 RJ-45 Ports
RJ-45 Ports (Auto MDI/MDIX): The RJ-45 ports are auto-sensing for 10Base-T, 100Base-TX, or
1000Base-T connections. Auto MDI means that the switch can connect to another switch or workstation
without changing the straight-through or crossover cabling. See the figures below for straight-through
and crossover cabling schematics.
 RJ-45 Pin Assignment
The following figures show the cabling schematics for straight-through and crossover cables:
The following figures show the 10,100, and 1000 Ethernet RJ45 pin outs.
2.7 Cabling
Use the four twisted-pair, category 5e, or the above cabling for the RJ-45 port connections. The cable

between the switch and the link partner (switch, hub, workstation, etc.) must be less than 100 meters
(328 ft.) in length.
2.8 Wiring the Power Inputs
There are two power inputs for normal and redundant power configurations. The power input
2 is used for wiring a redundant power configuration. See the following for terminal block
connector views.
Figure 2.6 Terminal Receptor: Power Input Contacts
To wire the power inputs:
1.
Make sure the power is not connected to the switch or the power converter before proceeding.
2.
Insert a small flat-bladed screwdriver in the V1+/V1- wire-clamp screws, and loosen the
screws.
3.
Insert the negative/positive DC wires into the V+/V- terminals of PW1. If setting up power
redundancy, connect PW2 in the same manner.
4.
Tighten the wire-clamp screws to secure the DC wires in place.

4. Web Management
4.1 Log In
To access the login window, connect the device to the network; see “Connecting the Switch to Ethernet
Ports”. Once the switch is installed and connected, power on the switch; see the following procedures
in Figure 4.1 to log into your switch. When the switch is first installed, the default network configuration
is set to DHCP enabled. You will need to make sure your network environment supports the switch
setup before connecting it to the network.
1.
Launch your web browser on a computer.
2.
In the browser’s address bar, type in the switch’s default IP address (192.168.1.254). The login
screen displays.
3.
Enter the default user name and password (admin/admin) to log into the management interface.
You can change the default password after you have successfully logged in.
4.
Click Login to enter the management interface.
Figure 4.1
4.2 Recommended Practices
Antaira recommends creating a best practices policy for securing your network. This type of policy
could be as simple as verifying that secure passwords have been used in place of default passwords
but may also include other measures to maintain the security of the network.
4.3 Changing Default Password
In keeping with good management and security practices, it is recommended that you change the
default password as soon as the device is functioning and setup correctly. The following details the
necessary steps to change the default password.
To change the password:
1.
Navigate to Tools > User Account.
2.
From the User drop-down menu, select the Admin (default) account.
3.
In the User Name field, enter admin for this account. It is not necessary to change the user name,
however, a change in the default settings increases the security settings.
