Introduction
The Server Technology Inc. Sentry family of products provides easy, practical, and secure solutions for
power distribution, power management and load-measurement for remote internetworking equipment
and branch AC circuits.
The Sentry PT40 Commander continues to support 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 networks.
Features and Benefits
PT40 Commanders are available in 4-outlet configurations for 100-120VAC and 208-240VAC up to
15A. See Models in Appendix C: Technical Specifications.
Communication Access Modes
PT40 Commanders are equipped standard with a Serial RS-232 port, out-of-band external modem
access and a 10/100 Base-T Ethernet port for Telnet and in-band web browser (HTML) access. The
optional integrated Global Security Modem is also available.
Power Distribution & Remote Management
A PT40 Commander distributes up to 15A AC power (dependant on model) and offers individual remote
control over the power on/off status of up to 4 devices.
Pass-Thru Port Access
The PT40 Commander’s integrated “One-to-Many” asynchronous communications switch offers serial
connections to up to 4 inter-networking device console ports for remote problem determination.
Load and Environment Measurement
The PT40 Commander’s load measurement feature 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 worry. 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 control screen interface.
With the optionally available Environmental Monitoring Control Unit (EMCU), the PT40 Commander
supports monitoring of key environmental conditions at the remote facility including temperature, humidity,
water/flooding and physical access.
Power-up Sequencing
When the PT40 Commander is powered on, each of the power outlets is powered sequentially with a
two-second delay between each outlet. Power sequencing staggers the individual loads, 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,
PT40 Commander outlets may be included in one or more named groups of outlets. Changes may then
be applied to all outlets in the named group with one easy command sequence.
Security
The PT40 Commander ships with one predefined administrative user account. The administrator may create
up to 128 user accounts, with individualized access to outlets, serial/Pass-Thru ports and commands. All
accounts support username and password protection. For configurations requiring multiple fully-privileged
users, the PT40 Commander allows the administrator to grant administrative privileges to other user
accounts in the system.
For added security, a user session will be automatically terminated after five minutes of inactivity; if a
user is called away unexpectedly, an unprotected channel will not remain open indefinitely.
User Interfaces and LEDs
The PT40 Commander features two types of user interfaces: the command line and the HTML
interface. For easy outlet recognition, both individual outlets and outlet groups may be assigned
descriptive names for use in control commands. For the on-site technician, LEDs on the PT40
Commander indicate individual outlet power status.

Interfaces
The Sentry has two interfaces: the HTML interface accessed via the HTTP enabled Ethernet
connections and the command line for serial and Telnet connections.
Outlet Naming and Grouping
For commands requiring an outlet name, you may specify it in one of two ways: a predefined absolute
name or a descriptive name assigned by an administrator.
Absolute names are specified by a period (.) followed by the tower letter, the infeed letter and outlet
number.
Example: The absolute name for outlet 8 on the B infeed of tower A is .AB8.
Outlets may also be included in one or more named groups of outlets, enabling you to issue a command
that affects all outlets in a named group.
Usernames and Passwords
The Sentry has one predefined administrative user account (username/password: admn/admn) and
supports a maximum of 128 defined user accounts
NOTE: For security, Server Technology recommends removal of the predefined administrative user account after a new
account with administrative rights has been created.
Only an administrative-level user may perform operations such as creating/removing user accounts and
command privileges, changing passwords and displaying outlet and user information. An administrator
may also view the status of and control power to all outlets.
The administrator may create additional user accounts and then grant these users the right to view the
status of and control power to specific outlets, groups and ports.
Usernames may contain from 1-16 characters and are not case sensitive; spaces are not allowed.
Passwords may contain up to 16 characters, and are case sensitive.

The HTTP/SSL configuration page used to enable or disable HTTP and SSL support, configure the port
number that the HTTP server watches and responds to, selection of the method of authentication used
and SSL access level. For more information on SSL see page 42 in Chapter 4: Advanced Operations.
Enabling or disabling HTTP or SSL support:
Select Enabled or Disabled from the appropriate Server drop-down menu and press Apply.
Changing the HTTP server port number:
In the HTTP Port field, enter the port number and press Apply.
Setting the HTTP authentication method:
The Sentry 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 username-password 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
Sentry SSL supports configuration of SSL connections as being either 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.

Click on the Edit link in the Action column next to the port to be configured.
On the subsequent Serial Port Edit page, select On or Off from the DSR Check drop-down menu and press Apply.
Enabling or disabling modem initialization strings:
By default, the Sentry assumes an external modem is attached to the Modem port and sends
initialization strings to that modem as necessary. The XLS series sends the initialization strings under
the following conditions:
• System start –DSR is high and DCD is low
• Normal operations – If DSR transitions from low to high and DCD is low
• Normal operations – After a session initiated from the Modem port ends
• Normal operations – After a Pass-Thru connection to the Modem port is disconnected
Click on the Edit link in the Modem port Action column.
On the subsequent Serial Port Edit page, select On or Off from the Modem Initializations drop-down
menu and press Apply.
Editing modem initialization strings:
Click on the Edit link in the Modem port Action column.
On the subsequent Serial Port Edit page, enter the initialization string in the appropriate field and press
Apply.
The Init1 and Init2 strings may be up to 48 characters. The Attention and Hang-up strings may be up to
16 characters.
Predefined Modem Initialization Strings
String Type String Description
Init 1 AT Gets modem attention
Init 2 AT E0 Q1 S0=1 S2=64 S12=50 &C1 &D2 Initializes default settings required
Attention @@@ Switches the modem to command mode
Hang-up ATH Forces a hang-up of an active connection
NOTE: Sentry Remote Power Managers do NOT support variable data-rate mode modems. The modem operating mode
must be set to fixed data-rate mode to avoid the data-rate being changed after initialization.
The modem manual must be referred to as the command(s) required to set the configuration to fixed data-rate mode vary
significantly from manufacturer to manufacturer. The modem should be configured directly from a PC using a terminal
program and the command &W be used to save the new configuration to memory and set it to default.
