Interfaces

The PT22 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.

For units with multiple infeed connectors, 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 PT22 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 user information. An administrator may also
view the status of all sensors and power inputs.

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.

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.
