Introduction
Initial Setup
Required network
settings
You must configure the following network settings of the MasterSwitch
PDU before it can operate on a network:
•IP address of the unit
• Subnet Mask
•IP address of the default gateway
Note: If a default gateway is not present, enter an IP address
of a computer that is on the same subnet and that is
always active.
Configuring TCP/IP
settings
To configure TCP/IP settings, see TCP/IP on page 15 and see the
MasterSwitch Installation and Quick Start Manual, included in printed
form with the MasterSwitch PDU and in Portable Document Format
(Install.pdf) on this CD-ROM.
Customizing your
configuration
After you configure MasterSwitch network settings, no further
configuration is required. The remaining MasterSwitch properties are
pre-configured to default settings at the factory. However, you may want
to customize these properties for your application. For more information,
see Managing the MasterSwitch PDU on page 5.
Auto-configuration The management card within the MasterSwitch PDU supports an auto-
configuration utility that you can use to create a configuration file, which
you can then download to other MasterSwitch PDUs, either to individual
units one at a time or to multiple units at the same time. For more
information, see the Management Card Addendum (addendum.pdf
on the MasterSwitch CD-ROM).

Managing the MasterSwitch PDU
Management Interfaces
Management
Options
After you configure a MasterSwitch PDU with the proper network
settings, you can manage the unit remotely through its Web, Telnet
Control Console, SNMP, and WAP interfaces.
You can also use the Control Console to manage a MasterSwitch PDU
locally through a serial connection.
Only one user at a time can access a MasterSwitch PDU. Serial
interface users (using a terminal emulator) have precedence over Telnet
users, and Telnet users have precedence over Web and WAP users.
Web interface To access and log on to the Web interface of the MasterSwitch PDU:
1. In the URL Location field of the Web browser, do one of the
following:
• If the Web port of the MasterSwitch PDU is set to the default
value of 80, enter http:// followed by the unit’s IP address.
The following example shows a typical IP address:
http://170.241.17.51
• If the Web port of the MasterSwitch PDU is set to a value other
than the default of 80, enter the System IP address (the IP
address of the unit) followed by a colon and the configured Web
port value (8000 in the following example).
http://170.241.17.51:8000
• If there is a DNS server entry for the MasterSwitch PDU, you
can choose to enter the DNS name to access the unit.

When you select the Local SMTP Server option for the Send via
setting, you must do one of the following:
• Make sure that forwarding is enabled at that server so that the
server can route e-mail to external SMTP servers.
Note: Always see your SMTP-server administrator before
changing the configuration of your SMTP server.
• Set up a special e-mail account for the Management Card.
This account then forwards the E-mail to an external e-mail
account.

Address
Defines the user and domain names of the recipient.
To use e-mail for paging, use the e-mail address for the recipient’s
pager gateway account (for example, myacct100@skytel.com). The
pager gateway generates the page.
Note: The recipient’s pager must be able to use text-based
messaging.
Send via
Lets you choose one of the following methods for routing e-mail:
• Send e-mail through the Management Card’s SMTP server.
Selecting Local SMTP Server, which is the recommended option,
ensures that the e-mail is sent before the unit’s 20-second time-out,
and, if necessary, is retried several times.
• Send e-mail directly to the recipient’s remote SMTP server. If you
select the Recipient’s SMTP Server option, and the remote SMTP
server is busy, the time-out may prevent some e-mail from being
sent, With this option, the management card tries to send the e-mail
only once.

Configuring and Using E-mail Notification
Configuring SMTP and DNS Settings
Requirements for
using SMTP
To use the Simple Mail Transfer Protocol (SMTP) to send e-mail when
an event occurs, you must define the following settings:
• The IP address of the Domain Name Service (DNS) server.
• The DNS name of the SMTP server and the From Address set-
tings for SMTP.
• The e-mail addresses for a maximum of four recipients.
Note: To page an e-mail recipient who uses a text-based
pager gateway, see the description of the To Address
setting in Settings on page 25.
DNS server To enable the Management Card to send e-mail messages, you must
use the TCP/IP & DNS option (Web interface) or DNS option (Control
Console) in the Network menu to identify the Domain Name Service
(DNS) server by its IP address.
If the unit does not receive a response from the DNS server within five
seconds, e-mail cannot be sent. Therefore, use a DNS server on the
same segment as the unit or on a nearby segment (but not across a
WAN).
After you define the DNS server’s IP address, verify that DNS is working
correctly by entering the DNS name of a computer on your network to
obtain the IP address for that DNS name.
SMTP settings The E-mail option in the Network menu accesses the following SMTP
settings:
Setting Description

Security
Security Features
Planning and
implementing
security features
As a network device that passes information across the network, the
MasterSwitch PDU is subject to the same exposure as other devices on
the network.
Use the information in this section to plan and implement the security
features appropriate for your environment.
Port assignments If a Telnet, FTP
, or Web server uses a non-standard port, a user must
specify the port when using the client interface, such as a Web browser.
The non-standard port address becomes an extra “password,” hiding
the server to provide an additional level of security. The TCP ports for
which the Telnet, FTP
, and Web servers listen are initially set at the
standard “well known ports” for the protocols.To hide the interfaces, use
any port numbers from 5000 to 65535.
User names,
passwords,
community names
All user names, passwords, and community names for SNMP are
transferred over the network as plain text. A user who is capable of
monitoring the network traffic can determine the user names and
passwords required to log in to the Administrator, Device Manager, and
Outlet User accounts of the Control Console or Web interface of a
MasterSwitch PDU. This security limitation of the protocols affects any
device using Telnet, a Web server, or an SNMP version 1 agent.

MasterSwitch Power Distribution Unit User’s Guide 40
Security
Authentication
Authentication
versus encryption
The MasterSwitch PDU controls access by providing basic
authentication through user names, passwords, and IP addresses, but
provides no type of encryption. These basic security features are
sufficient for most environments, in which sensitive data is not being
transferred. To ensure that data and communication between the
MasterSwitch PDU and the client interfaces, such as Telnet and the
Web browser, cannot be captured, you can provide a greater level of
security by enabling MD5 authentication (described below) for the Web
interface.
MD5
authentication
(Web interface)
The Web interface option for MD5 authentication enables a higher level
of access security than the basic HTTP authentication scheme. The
MD5 scheme is similar to CHAP and PAP remote access protocols.
Enabling MD5 implements the following security features:
• The Web server requests a user name and a password phrase
(distinct from the password). The user name and password
phrase are not transmitted over the network, as they are in
basic authentication. Instead, a Java login applet combines the
user name, password phrase, and a unique session challenge
number to calculate an MD5 hash number. Only the hash num-
ber is returned to the server to verify that the user has the cor-
rect login information; MD5 authentication does not reveal the
login information.
• In addition to the login authentication, each form post for config-
uration or control operations is authenticated with a unique chal-
lenge and hash response.
• After the authentication login, subsequent page access is
restricted by IP addresses and a hidden session cookie. (You
must have cookies enabled in your browser.) Pages are trans-
mitted in their plain-text form, with no encryption.

MD5
authentication
(Web interface),
continued
If you use MD5 authentication, which is available only for the Web
interface, disable the less secure interfaces, including Telnet, FTP
, and
SNMP
. For SNMP
, you can disable write-only access so that read
access and trap facilities are still available.
Although MD5 authentication provides a much higher level of security
than the plain-text access methods, complete protection from security
breaches is almost impossible to achieve. Well-configured firewalls are
an essential element in an overall security scheme. For additional
information on MD5 authentication, see RFC document #1321 at the
Web site of the Internet Engineering Task Force. For CHAP
, see RFC
document #1994.

Product Information
Life-Support Policy
General policy American Power Conversion (APC) does not recommend the use of any
of its products in the following situations:
• In life-support applications where failure or malfunction of the
APC product can be reasonably expected to cause failure of the
life-support device or to affect significantly its safety or
effectiveness.
•In direct patient care.
APC will not knowingly sell its products for use in such applications
unless it receives in writing assurances satisfactory to APC that (a) the
risks of injury or damage have been minimized, (b) the customer
assumes all such risks, and (c) the liability of American Power
Conversion is adequately protected under the circumstances.
Examples of life-
support devices
The term life-support device includes but is not limited to neonatal
oxygen analyzers, nerve stimulators (whether used for anesthesia, pain
relief, or other purposes), autotransfusion devices, blood pumps,
defibrillators, arrhythmia detectors and alarms, pacemakers,
hemodialysis systems, peritoneal dialysis systems, neonatal ventilator
incubators, ventilators (for adults or infants), anesthesia ventilators,
infusion pumps, and any other devices designated as “critical” by the
U.S. FDA.
Hospital-grade wiring devices and leakage current protection may be
ordered as options on many APC UPS systems. APC does not claim that
units with these modifications are certified or listed as hospital-grade by
APC or any other organization. Therefore these units do not meet the
requirements for use in direct patient care.
