1. Introduction
Product Description
The SM12XPA Fiber Aggregation Switch is a managed Layer 3 (L3) Multi-Gigabit Ethernet fiber switch offering
powerful Layer 2 and basic Layer 3 features for improved functionality. It also supports enhanced security
features such as IP source guard and Access Control Lists to guard networks against unauthorized access.
The SM12XPA switch provides 340 Gbps switching capacity with (12) 1G/10G SFP+ and (2) 1G/10G/25G SFP28
slots and (1) RJ-45 console port. It offers high performance and reliability for high bandwidth aggregation and
access network applications. The embedded Device Managed System (DMS) software is easy to use and
simplifies configuration, installation, and troubleshooting of devices in applications with high fiber density.
The SM12XPA offers an improved user experience, and lowers operating and maintenance costs.

for managing connectivity at the Ethernet service level.
APS
Ethernet Automatic Protection Switching (APS) is a linear protection scheme designed
to protect VLAN based Ethernet networks.
Keychain
A keychain is a sequence of keys that provides dynamic authentication to ensure
secure communication by periodically changing the key and authentication algorithm
without service interruption. When the system time is within the lifetime of a key in a
keychain, an application uses the key to authenticate incoming and outgoing packets.
The keys in the keychain take effect one by one according to the sequence of the
configured lifetimes. In this way, the authentication algorithms and keys are
dynamically changed to implement dynamic authentication.

33847 Rev. B https://www.lantronix.com/ 9
TSN
The Time-Sensitive Networking (TSN) Task Group (TG) is a part of the IEEE 802.1
Working Group (WG). The charter of the TSN TG is to provide deterministic services
through IEEE 802 networks (i.e., guaranteed packet transport with bounded latency,
low packet delay variation, and low packet loss).
TAS
A time-triggered scheduling mechanism called Time-Aware Shaper (TAS) is one of the
IEEE802.1 Standards. TAS uses a parameter called a Gate Control List (GCL) to
control each class of stream or traffic.
Layer 3 Switching
IPv4 L3 Static routing
IPv4 Unicast: Static routing. Static routing is a form of routing that occurs when a router
uses a manually-configured routing entry, rather than information from dynamic routing
traffic.
IPv6 L3 Static routing
IPv6 Unicast: Static routing. Routing protocols interfaces can be dynamically or
statically assigned. Static network routing has benefits and drawbacks as compared to
implementing dynamic routing protocols
RIP v1/v2 L3 Dynamic
routing
Routing Information Protocol (RIP) protocols are intra-domain (interior) routing
protocols based on distance vector routing and used inside an autonomous system.
For more information see RIP v1: IETF RFC 1923 or RIP v2 2: IETF RFC 2543.
OSPF v2 L3 Dynamic
routing
OSPF is a link-state routing protocol designed to be run internal to a single
Autonomous System. Each OSPF router maintains an identical database describing
the Autonomous System's topology. From this database, a routing table is calculated
by constructing a shortest-path tree. For more OSPF v2 information see IETF RFC
2328.
OSPF
Open Shortest Path First (OSPF) is a link-state routing protocol. It is designed to be
run internal to a single Autonomous System. Each OSPF router maintains an identical
database describing the Autonomous System's topology. From this database, a routing
table is calculated by constructing a shortest-path tree.
RIP
The Routing Information Protocol (RIP) protocol lets routers exchange network
topology information. It is considered an interior gateway protocol, typically used in
small to medium-sized networks.
Security
Secure Shell (SSH) SSH secures Telnet traffic in or out of the switch, SSH v1 and v2 are supported
Secure Sockets Layer
(SSL)
SSL encrypts the http traffic, allowing advanced secure access to the browser-based
management GUI in the switch
IEEE 802.1X
•IEEE802.1X: RADIUS authentication, authorization and accounting, MD5 hash,
guest VLAN, single/multiple host mode and single/multiple sessions
•Supports IGMP-RADIUS based 802.1X
•Dynamic VLAN assignment
Layer 2 Isolation
Private VLAN Edge
PVE (also known as protected ports) provides L2 isolation between clients in the same
VLAN. Supports multiple uplinks
Port Security Locks MAC addresses to ports, and limits the number of learned MAC address
IP Source Guard Prevents illegal IP address from accessing to specific port in the switch
RADIUS/ TACACS+ Supports RADIUS and TACACS+ authentication. Switch acts as a client

33847 Rev. B https://www.lantronix.com/ 10
Storm Control
Prevents traffic on a LAN from being disrupted by a broadcast, multicast, or unicast
storm on a port
DHCP Snooping A feature that acts as a firewall between untrusted hosts and trusted DHCP servers
ACLs
Supports up to 256 entries. Drop or rate limitation based on:
•Source and destination MAC, VLAN ID or IP address, protocol, port,
•Differentiated services code point (DSCP) / IP precedence
•TCP/ UDP source and destination ports
•802.1p priority

and events) for enhanced traffic management, monitoring and analysis
Port Mirroring
Traffic on a port can be mirrored to another port for analysis with a network analyzer or
RMON probe. Up to N-1 (N is Switch’s Ports) ports can be mirrored to single
destination port. A single session is supported.
UPnP
The Universal Plug and Play Forum was formed to standardize discovery and control of
networked devices. See the Open Connectivity Foundation webpage.

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 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.

Lantronix SM12XPA Install Guide
33847 Rev. B https://www.lantronix.com/ 18
Warnings :
1. The switch is an indoor device. If you must use it to connect outdoor devices such as outdoor IP cameras
or outdoor WiFi Aps with cable, you must install an arrester on the cable between outdoor device and the
switch.
Add an arrester between outdoor device and this switch
2. The marking information is located at the bottom of apparatus (IEC 62368-1).
3. The equipment is not suitable for use in locations where children are likely to be present.
4. Restricted access location.
Danger: 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.

Connecting to the Console Port
Use the provided RJ45 to DB9 Serial Console Cable to connect a PC to the switch Console port. The Console
port is for local management by using a terminal emulator or a computer with terminal emulation software.
•DB9 connector connect to PC COM port
•Baud rate: 115200bps
•8 Data bits, 1 Stop bit
•Priority: None
•Flow control: None
Connecting to a Management Port
There is no dedicated Management port, just one Console port (RJ45) and 14 SFP ports. You need to have a
fiber NIC to directly connect your PC to this switch. Otherwise, you need to have another management switch
between your PC and the switch.
Installing SFP+/SFP28 Modules
Note: see the related SFP device manual for important Safety warnings. See the Lantronix SFP page for our full
line of SFP transceivers. See the FOA webpage for additional information. The Fiber Optic Association, Inc.is an
international non-profit educational association chartered to promote professionalism in fiber optics through
education, certification and standards. Note: The SFP+/SFP28 ports should use UL Listed Optional Transceiver
products, Rated 3.3Vdc, Laser Class 1.
Before you begin installing SFP+/SFP28 modules, observe these guidelines:
•Do not remove the rubber caps from the fiber-optic cable until you are ready to connect the cable. The
plugs and caps protect the module ports and cables from contamination and ambient light.
•To prevent ESD damage, follow your normal board and component handling procedures when connecting
cables to the switch and other devices.
Caution: Removing and installing an SFP+/SFP28 module can shorten its useful life. Do not remove and insert
any SFP module more often than is absolutely necessary.
You can install or remove a mini-GBIC SFP+/SFP28 module from an SFP+ or SFP28 port without having to
power off the switch.
1. Insert the module into the SFP+/SFP28 port.
2. Press firmly to ensure that the module seats into the connector.
