SecureLinx SLP Remote Power Manager 6
1: Introduction
The Lantronix SLP Remote Power Manager family of products provides easy,
practical, and secure solutions for power distribution, power management and loadmeasurement for remote equipment and branch AC circuits.
The SLP Remote Power Manager supports the elimination of unnecessary trips to
remote locations by allowing remote control of the power on/off status for distant
critical equipment, minimizing the impact of locked-up devices on mission-critical
systems.
Features and Benefits
SLP models are available in 8-outlet and 16-outlet configurations for 100-120VAC
and 208-240VAC up to 16A. See Models on page 59.
Communication Access Modes
All models are equipped standard with a RS-232 (serial) port and a 10/100 Base-T
Ethernet port for Telnet, Secure Shell (SSH), and web browser access.
Power Distribution
Up to 16A of AC power (dependant on model) can be distributed across up to sixteen
attached devices. See Models on page 59 for available models.
Remote Power Management
Remote control of power outlets allows individual on/off and reboot control of up to 16
devices.
Load and Environment Measurement
Load measurement eliminates guesswork by supplying the cumulative operating load
in amperes. This allows on-site technicians to maximize the equipment installed and
operated on a circuit without concern. Use of the circuit is maximized, while
effectively allowing a 10% to 20% safety margin. Remote users also may access this
information at any time from the command line or web browser interface.
Optionally, temperature and humidity sensors allow monitoring of key environmental
conditions at remote facilities.
Power-up Sequencing
When powered on, each of the power outlets power sequentially with a two-second
delay between each outlet. Power sequencing staggers the individual loads,
SecureLinx SLP Remote Power Manager 7
1: Introduction
eliminating the potential of a blown fuse or circuit breaker due to excessive in-rush
current and allows circuit support for operating load capacities of 80% to 90%.
Outlet Grouping
For operations across multiple attached devices or devices with multiple or redundant
power supplies, include outlets in one or more named groups of outlets. This allows
changes to all outlets in the named group with a single command sequence.
Security
Units ship with one predefined administrative user account. The administrator can
create up to 128 user accounts, with individualized access to outlets and commands.
All accounts support username and password protection. For configurations
requiring multiple fully-privileged users, the administrator can grant administrative
privileges to other user accounts in the system.
User Interfaces and LEDs
Two types of user interfaces are available: the web browser and the command line
interface. For easy outlet recognition, assign descriptive names to both individual
outlets and outlet groups for use in control commands. For the on-site technician,
LEDs indicate individual outlet power status and cumulative power load.
Automatic Timeout
For added security, a user session automatically terminates after five minutes of
inactivity; if a user is called away unexpectedly, an unprotected channel does not
remain open indefinitely.

Note: The default port number for HTTP is 80.
Setting the HTTP authentication method:
The HTTP server supports two authentication methods for security and validation of
the username-password – Basic and MD5 digest.
The Basic method utilizes Base64 encoding to encode and deliver the usernamepassword over the network to the HTTP server for decoding and authentication. This
basic method is supported by all web browsers and offers a minimum level of
security.
Note: The Base64 algorithm is widely-known and susceptible to packet-
sniffer attack for acquisition of the encoded username-password string.
The MD5 digest method provides stronger protection utilizing one-way encoded hash
numbers, never placing the username-password on the network. Instead, the
sending browser creates a challenge code based on the hash algorithm, provided
username-password and unique items such as the device IP address and timestamp,
which is compared against the HTTP server internal user database of valid challenge
codes. The MD5 digest method offers a higher level of security than the Basic
method but at present is not supported by all browsers.
Note: MD5 is known to be fully supported by Internet Explorer 5.0+
Select Basic or MD5 from the Authentication drop-down menu and press Apply.
Setting SSL access level
SSL access may be configured as optional or required. The default access level is
set to optional.
Optional –Both non-secure (HTTP) and SSL encrypted connections (HTTPS)
are allowed access.
Required – ONLY SSL encrypted connections (HTTPS) are allowed access.
Select Optional or Required from the Secure Access drop-down menu and press
Apply.
Serial Port
The Serial Port configuration page is used for maintenance of the serial port.
