SLB™ Branch Office Manager User Guide 12

2: Overview

Meets Needs of Branch Offices

Designed to meet the specific needs of the remote branch office, the SLB branch of f ic e
manager conserves rack space and reduces costs by enabling system administrators at
a main corporate facility to manage the IT equipment distributed among branch of fic es
simply and cost-effectively.

Branch offices are facilities that are typically remote or “distributed IT” locations, likely
located off-site 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 13

2: Overview

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 must be in the same
physical location as the equipment. SLB devices give the user a way to access them
remotely from anywhere there is a network or modem connection.

The SLB can access and administer many types of equipment, such as:

 Servers: Unix, Linux, Windows 2003, 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 branch office manager is used in many types of business, for example:

 Banking and finance
 Insurance companies
 Healthcare
 Retail Sales
 Information Technology
 Education and campus style facilities
 Hospitality
 Manufacturing Facilities

Benefits

The key benefits of using the SLB branch office manager:

 Saves space: Compact design merges the functionality of three solutions into a

 Saves money: Enables remote management and troubleshooting without

 Saves time: Provides instant access and reduces response time, improving

 Simplifies access: Enables 24/7 access to your equipment securely and

1U rack solution, reducing required rack space and total cost of ownership.

sending a technician onsite, resulting in reduced travel costs and increased
network uptime.

efficiency.

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.

SLB™ Branch Office Manager User Guide 14

The SLB device also provides features such as convenient text menu systems, break­safe operation, port buffering (logging), remote authentication, and Secure Shell (SSH)
access. Dial-up modem support ensures access when the network is not available.

Models

Two SLB models have the following hardware components:

2: Overview

 Two Models: The SLB branch office manager is available in a 100-120 VAC

output model (SLB088411-01) with NEMA 5-15R type outlets and a 208-240
VAC output model (SLB088412-01) with IEC60320/C13 type outlets.

 Power Outlets: Each model has four outlets that allow power management

and control (on/off/reboot) of the attached equipment using a simple web or
command line interface.

 Serial Device Ports: Eight serial RS-232C (EIA-232) device ports are for

remote console 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 D: Adapters and Pinouts for more information on serial
adapters and pin-outs.

 Unmanaged Ethernet Switch: A built-in 8-port unmanaged Ethernet switch

provides convenience and hel ps further reduce required rack space.

 Ports and Modem Slots: The SLB branch office manager has two 10/ 100

Ethernet ports (referred to in this User Guide as Eth1 and Eth2) and a front
panel serial console port (RJ45). The SLB device has two 32-bit CardBus
(PC card) slots to support storage cards or a PC Card modem for dial-in
access. The list of supported cards is available on the Lantronix website.

SLB™ Branch Office Manager User Guide 16

2: Overview

Protocols Supported

The SLB branch office manager supports the TCP/IP network protocol as well as:

 SSH, Telnet, PPP, NFS, and CIFS for connections in and out of the SLB device
 SMTP for mail transfer
 DNS for text-to-IP address name resolution
 SNMP for remote monitoring and management

 HTTPS (SSL) for secure browser-based configuration
 NTP for time synchronization
 LDAP, NIS, RADIUS, CHAP, PAP, Kerberos, and TACACS+ for user

authentication

For brief descriptions of these protocols, see Appendix 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, pass wor d, and
access rights. Other user profile access options may include externally configured
authentication methods such as RADIUS, TACACS+, NIS, and LDAP.

Power Outlet Control

With the SLB branch office manager’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 device 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

Application Example

The figure below is an example deployment. An SLB branch office manager is deployed
in each branch office and an (optional) SLM 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.

Note: The SLB branch office manager can also be the authentication gateway to a

network architecture that is not VPN-based.

The SLB device provides Ethernet switch service (blue), remotely controlled and
monitored AC power (orange), console management (green), and traditional, wir e d
telephone network (PSTN) access (yellow).

2: Overview

SLB™ Branch Office Manager User Guide 18

A system administrator, upon losing IP connectivity to a server, takes the following steps:

 Views the server’s Ethernet interface state information provided by the SLB

branch office manager.

 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 SLM management appliance) and
checks the server’s system parameters.

 If the server is not responsive on the console port, commands the SLB branch

office manager to reboot the server’s power.

 If the entire branch office loses IP connectivity, dial in to the SLB device to

perform the diagnostic functions

Connecting to a Device Port

You can connect any device that has a serial console port to a device port on the SLB
branch office manager for remote administration. The console port must support the RS­232C interface.

Note: Many servers must either have the serial port enabled as a console or the

keyboard and mouse detached. Consult the server hardware and/or software
documentation for more informat ion.

To connect to a device port:

1. Connect one end of the Cat 5 cable to the device port.

2. Connect the other end of the Cat 5 cable to a Lantronix serial console adapter.

Note: To connect a device port to a Lantronix® SLP™ management appliance, use the

rolled serial cable provided with the SLB branch office manager, a 200.2225 adapter and
Cat 5 cabling, or the ADP010104 adapter that eliminates the need for an additional Cat5
patch cable between the adapter and the connected equipment. See D: Adapters and

Pinouts for more information about Lantronix adapters.

3. Connect the adapter to the serial console of the serial device.

Figure 3-1. CAT 5 Cable Connection

Connecting to a Network Port

The SLB device’s network ports (10Base-T/100Base-TX) allow remote access to the
attached devices and the system administrative functions. Use a standard RJ45­terminated Category 5 cable to connect to the network port.

Note: One possible use for the two Ethernet ports is to have one port on a

private, secure network, and the other on an unsecured network.

Connecting a Terminal

The console port is for local access to the SLB branch office manager and the attached
devices. You may attach a dumb terminal or a computer with terminal emulation to the
console port. The SLB console port uses RS-232C protocol and supports VT100
emulation. The default baud rate is 9600.

To connect the console port to a terminal or computer with terminal emulation, Lantronix
offers optional adapters that provide a connection between an RJ45 jack and a DB9 or
DB25 connector. The console port is configured as DTE. For more information,

on the Support menu.

Connecting to a Power Source

The SLB branch office manager consumes less than 20W of electrical power.
The SLB device has a universal auto-switching AC power supply. The power supply

accepts AC input voltage between 100 and 240 VAC with a frequency of 50 or 60 Hz.
Rear-mounted IEC-type AC power connector(s) are provided for universal AC power
input (see page 22 for included power cords).

Figure 4-2. AC Power Input

Connecting Devices to Power Outlets

To avoid the possibility of noise due to arcing:

1. Keep the device’s on/off switch in the off position until after it is plugged into
the outlet, or log in to the unit and turn the outlets off before connecting the
devices.

2. Connect devices to the outlets.

There are four power outlet status LEDs next to outlet number 1. The status LED
for outlet 1 is at the top. If the LED for an outlet is dark the outlet is turned off; if it is
lit the outlet is turned on.

Connecting Devices to the 8-Port Ethernet Switch

To connect devices to the unmanaged Ethernet switch:

1. Use the included 1Ft Ethernet patch cable to connect Ethernet port 1 on the SLB
branch office manager to one of the switch ports.

Figure 3-3. 8-Port Ethernet Switch

Note: The eight unmanaged Ethernet ports are not internally connected

to the other two Ethernet ports.

2. Use a standard Ethernet patch cable to connect another switch port to your
network.

3. Up to 6 more Ethernet devices may be connected to your network. Use standard
Ethernet patch cables from the Ethernet devices to the SLB device's switch ports.

An example of a standard Ethernet patch cable is the Lantronix 200.0062 RJ45 TO
RJ45 CAT5 CABLE (LAN PINNING) 6.6 Ft.

Typical Installations

Following are illustrations showing some typical ways to install the SLB branch of fice
manager. In Figure 3-4, three serial devices (a server, a Cisco switch, and a firewall)
connect to the SLB device's serial ports, unmanaged switch ports, and power outlets.
This setup enables the SLB branch office manager to manage the devices, connect the
devices to the network, and provide power to the devices. An SLB switch port connects
the Lantronix Spider (optional), a “Distributed KVM” product that provides remote and
secure access to the attached server over the network. In addition, the SLB branch office
manager connects to a modem for out-of-band dial-up access.
