Enables system administrators to remotely manage devices with serial console ports, e.g.,
Linux, Unix, and recent versions of Windows servers, routers, switches, telecom, and building
access equipment.
Provides data logging, monitoring, and secure access control via the Internet
Power Management Outlets for Power Connectivity
8 outlets for power connectivity
Provides ability to control power individually to all attached equipment

2: Introduction
Designed for Branch Offices and Similar Environments
Designed to meet the specific needs of the remote branch offices and environments alike, the SLB
branch office manager conserves rack space and reduces costs by enabling system
administrators at a main corporate facility to manage the IT equipment distributed among branch
offices simply and cost-effectively.
Branch offices are facilities that are typically remote or "distributed IT" locations, likely located offsite of corporate headquarters or large-scale enterprise facilities. These distributed facilities
typically do not have an on-site maintenance staff or IT System Administrator.
Typically, the branch office environment has some of the following characteristics:
Space is limited to 1U rack space or shelf mounted desktop unit
Closet-mounted or wall-attached rack
Limited air and power conditioning
Limited number of network devices and servers
No on-site maintenance staff
Ethernet or dial-up modem access is required
SLB™ Branch Office Manager User Guide 21
2: Introduction
Typical Equipment
You can configure, administer, and manage IT equipment in a variety of ways, but most devices
have one method in common: an RS-232 serial port, sometimes called a console, auxiliary, or
management port. These ports are often accessed directly by connecting a terminal or laptop to
them, meaning that the user typically must be in the same physical location as the equipment.
Eliminating the need for a physical presence, the Lantronix SLB unit provides remote access to the
equipment from anywhere there is a network or modem connection.
The SLB branch office manager can access and administer many types of equipment, such as:
Servers: Unix, Linux, Windows Server 2003 or higher, and others
Networking equipment: Routers, switches, storage networking
Telecom: PBX, voice switches
Other systems with serial interfaces: Heating/cooling systems, security/building access
systems, UPS, medial device.
Types of Business
The SLB unit is used in many types of environments, for example:
Banking and finance
Insurance companies
Healthcare
Retail Sales
Information Technology
Education and campus style facilities
Hospitality
Manufacturing Facilities
Base Station Control and Management
Benefits
The key benefits of using the SLB branch office manager:
Saves space: Compact design merges the functionality of two solutions into a 1U rack
solution, reducing required rack space and total cost of ownership.
Saves money: Enables remote management and troubleshooting without sending a technician
onsite, resulting in reduced travel costs and increased network uptime.
Saves time: Provides instant access and reduces response time, improving efficiency.
Simplifies access: Enables 24/7 access to your equipment securely and remotely after hours
and on weekends and holidays-without having to schedule visits or arrange for off-hour
access.
Protects assets: Provides the highest levels of encryption and security features
(authentication, authorization, and IP filters) to ensure that your IT infrastructure and data
assets are protected.
The SLB unit also provides features such as convenient text menu systems, break-safe operation,
port buffering (logging), remote authentication, and Secure Shell (SSH) access. Dial-up modem
support ensures access when the network is not available.

management of the attached equipment. These match the RJ45 pin-outs of the console ports
of many popular devices found in a network environment, and where different can be
converted using Lantronix adapters. See the appendix, Appendix C: Adapters and Pinouts for
more information on serial adapters and pin-outs.

2: Introduction
SNMP with custom traps for remote monitoring and management
FTP and SFTP for file transfers and firmware upgrades
TFTP and HTTPS for firmware upgrades
DHCP and BOOTP for IP address assignment
HTTPS (SSL) for secure browser-based configuration
NTP for time synchronization
LDAP, NIS, RADIUS, CHAP, PAP, Kerberos, and TACACS+ for user authentication
IPsec for VPN access
For brief descriptions of these protocols, see Appendix D: Protocol Glossary.
Access Control
The system administrator controls access to attached servers or devices by assigning access
rights to up to 128 user profiles. Each user has an assigned ID, password, and access rights.
Other user profile access options may include externally configured authentication methods such
as RADIUS, TACACS+, NIS, and LDAP. Groups are supported in LDAP, RADIUS (via VSA), and
TACACS+ (using priv_lvl).
Power Outlet Control
With the SLB unit's built-in power management capability, system administrators can remotely
control the power (on/off/reboot) individually to all IT equipment in the branch office, ensure safe
power distribution, and reduce "in-rush" current overload. If SNMP traps are enabled, a trap
(alarm) is sent if the total current for all outlets exceeds a threshold.
Device Port Buffer
The SLB branch office manager supports real-time data logging for each device port. The port can
save the data log to a file, send an email notification of an issue, or take no action.
You can define the path for logged data on a port-by-port basis, configure file size and number of
files per port for each logging event, and configure the device log to send an email alert message
automatically to the appropriate parties indicating a particular error.
Configuration Options
You may use the backlit front-panel LCD display for initial setup and configuration and to view
current network, console, and date/time settings, and get power outlet status.
Both a web interface viewed through a standard browser and a command line interface (CLI) are
available for configuring the SLB settings and monitoring performance.

Application Example
The figure below is an example deployment. An SLB unit is deployed in each branch office and an
(optional) vSLM management appliance at the main office. The branch offices are interconnected
(always on) by VPN routers overlaid on the Internet, and also interconnected (on demand) through
the analog phone system.

The SLB unit provides remotely controlled and monitored AC power (orange), console
management (green), and traditional, wired telephone network (PSTN) access (yellow).

2: Introduction
A system administrator, upon losing IP connectivity to a server, takes the following steps:
1. Views the server's Ethernet interface state information provided by the SLB branch office
manager.
2. If the Ethernet interface is faulty, connects to the server's console port by means of the SLB
web page or CLI (optionally via the vSLM management appliance) and checks the server's
system parameters.
3. If the server is not responsive on the console port, commands the SLB to reboot the server's
power.
4. If the entire branch office loses IP connectivity, dial in to the SLB to perform the diagnostic
functions

standard. Category 5 cabling with RJ45 connections is used for the device port connections and
for the console port. (For pinout information, see Adapters and Pinouts on page 338.)
Note: RJ45 to DB9/DB25 adapters are available from Lantronix.
Device ports and the console port support the following baud-rate options: 300, 600, 1200, 2400,
4800, 9600, 19200, 38400, 57600, 115200, and 230400 baud.

Network Connections
The SLB network interfaces are 10Base-T/100Base-TX connectors for use with a conventional
Ethernet network. Use standard RJ45-terminated Category 5 cables. Network parameters must be
configured before the SLB branch office manager can be accessed over the network.
Note: One possible use for the two Ethernet ports is to have one port on a private,
secure network and the other on a public, unsecured network.
