SM12DP2XA Managed Gigabit Ethernet Fiber Switch Quick Start Guide
The SM12DP2XA L2+ Managed Switch is a next-generation Fiber Switch offering full suite of L2 features and
additional 10GbE uplink connections. Advanced L3 features such as Static Route deliver better cost performance
and lower total cost of ownership in Enterprise networks or backbone via fibber or copper connections.
The SM12DP2XA provides 12 GbE SFP ports, 2 RJ45 ports, 2 10GbE SFP+ ports and RJ45 Console port with built-in
AC and DC dual power supplies. SM12DP2XA provides front access to all data and management ports in a
compact form factor that facilitates desktop, wall-mount, or rack-mount installations.
See the Install Guide for important Cautions and Warnings, Compliance and Safety Statements, Key Features,
Specifications, Front Panel, Site Preparation, Installation, Cabling, Unpacking, Mounting, Connecting to Power,
Initial Switch Configuration, and Troubleshooting, Warranty, Support and Compliance information.
Unpacking: 1. Carefully unpack all SM12DP2XA contents. 2. Verify receipt of all SM12DP2XA components.
Contact your sales representative if any items are missing. 3. Place the SM12DP2XA and related materials near
the install location. 4. Save the SM12DP2XA shipping carton and packing materials for possible future use.
Front Panel: The switch front panel contains the power inputs, ports, LEDs and RESET button.
1000BASE-T Ports: The switch contains 10/100/1000BASE-T RJ-45 ports. All RJ-45 ports support automatic
MDI/MDI-X operation, auto-negotiation and IEEE 802.3x auto-negotiation of flow control, so the optimum data
rate and transmission can be selected automatically.
SFP and SFP+ Transceiver Slots: The switch supports Small Form Factor Pluggable (SFP) transceiver slots port 1 to
port 12, and port 15 to port 16 are 10G SFP+. In the default configuration, if an SFP transceiver (purchased
separately) is installed in a slot and has a valid link on the port, the associated RJ-45 port is disabled. The optional
Gigabit SFP transceiver can be used for a backbone connection between switches, or for connecting to a
high-speed server. See the specific SFP manual for important cautions and warnings.
CONSOLE Port: The switch has one RJ-45 CONSOLE port for CLI access via the provided RS232 DB9 to RJ45 Cable.
Note: Cross-over cabling to the Console port is not supported.
Front Panel LEDs: The switch includes a LED panel for system and port indications that simplify installation and
network troubleshooting. See the Install Guide for Port Status LED and System Status LED details.

RST (Reset) Button: press and hold for 2-7 seconds to reset or 7-12 seconds to restore to factory defaults:
Task
Press RST button for
SYS LED Behavior
Port Status LED Behavior
Reset the Switch

Restore to Defaults
7 ~ 12 seconds
Blinking Green
All LEDs stay ON
Mounting: Mount the switch in a standard 19-inch equipment rack, on a desktop, or shelf; see the Install Guide.
Cabling: Make sure that the cables are suitable for your operating environment. For fiber optic connections, use
50/125 or 62.5/125 micron multimode fiber or 9/125 micron single-mode fiber. For copper connections, use UTP
for RJ-45 connections. For 1G bps connections use Category 5, 5e, 6, or 6a.
Connecting to Power: The SM12DP2XA front panel has two power inputs for power
redundancy; the switch has a 100~240 VAC power socket for AC power Input and a
24-48 VDC power input via the terminal block. Using both Power Supplies provides
power failover when power supplies are connected to different circuits to. With fiber
and copper cabling completed, and AC and/or DC power applied, the port LEDs light,
the SYS LED flashes, the AC and/or DC LEDs light and the SYS LED goes from flashing
to steadily lit. See the Install Guide for Connecting to an AC and/or DC Power source.
Initial Switch Configuration: Initial switch configuration can be via CLI or web browser. The factory defaults are
IP Address: 192.168.1.77, User Name: admin, and Password: admin.
CLI Configuration: The command-line interface (CLI) is a text-based interface
that you can access the CLI through either a direct serial connection to the
device or a Telnet session. An RJ-45 cable is used for connecting a terminal or
terminal emulator to the SM12DP2XA RJ-45 port to access the CLI. Attach the
RJ-45 serial port on the switch front panel to the cable for Telnet/CLI
configuration. Attach the other end of the DB-9 cable to a PC running Telnet.
See the CLI Reference for initial switch configuration via CLI.
Web UI Configuration: The left-hand menu contains two main tabs (Switch and
DMS) each with several sub-tabs for configuring and monitoring the switch’s
major functions. The major Switch tab functions include System, Ports, DHCP,
Security, VLAN, QoS, Diagnostics, and Maintenance. The DMS (Device
Management System) functions are DMS Mode, Graphical Monitoring,
Management, and Maintenance. See the Web User Guide for initial switch
configuration via web browser.
