Quick Configuration
Overview You must configure the following TCP/IP settings before the Rack PDU
can operate on a network:
•IP address of the Rack PDU
• Subnet mask
• Default gateway
TCP/IP configuration
methods
Use one of the following methods to define the TCP/IP settings:
• APC Management Card Wizard (See “APC Management Card
Wizard” on page 8.)
• BOOTP or DHCP server (See “BOOTP & DHCP configuration”
on page 8.)
• Local computer (See “Local access to the control console” on
page 11.)
• Networked computer (See “Remote access to the control console”
on page 11.)
Warn
i
ng
Disregard the procedures in this section if you have APC
InfraStruXure Manager as part of your system. See the
InfraStruXure Manager’s documentation for more
information.
Note
If a default gateway is unavailable, use the IP address of a
computer that is located on the same subnet as the Rack
PDU and that is usually running. The Rack PDU uses the
default gateway to test the network when traffic is very
light.

APC Management Card
Wizard
You can use the APC Management Card Wizard at a Windows® 98,
Windows NT® 4.0, Windows 2000, or Windows XP computer to
configure a Rack PDU.
1. Insert the APC Switched Rack PDU Utility CD into a computer on
your network.
2. Launch the Wizard, when prompted, or, if prompted to restart the
computer, access the Wizard from the Start menu after the
computer has restarted.
3. Wait for the Wizard to discover the unconfigured Rack PDU, then
follow the on-screen instructions.
BOOTP & DHCP
configuration
The Boot Mode setting, a TCP/IP option in the Rack PDU’s Network
menu, identifies how TCP/IP settings will be defined. The possible
settings are Manual, DHCP only, BOOTP only, and DHCP &
BOOTP (the default setting).
With Boot Mode set to DHCP & BOOTP, the Rack PDU attempts to
discover a properly configured server. It first searches for a BOOTP
server, and then a DHCP server. It repeats this pattern until it discovers a
BOOTP or DHCP server.
Note
If you leave the Start a Web browser when finished
option enabled, you can use apc for both the user name
and password to access the Rack PDU through your
browser.
Note
The DHCP & BOOTP setting assumes that a properly
configured DHCP or BOOTP server is available to provide
TCP/IP settings to the Rack PDU. If these servers are
unavailable, see “APC Management Card Wizard” on this
page, “Local access to the control console” on page 11, or
“Remote access to the control console” on page 11 to
configure the TCP/IP settings.
For more information, see “BOOTP” on page 9 or “DHCP”
on page 10.

Switched Rack PDU Installation and Quick Start 9
BOOTP. You can use an RFC951-compliant BOOTP server to configure
the TCP/IP settings for the Rack PDU. If the BOOTP server is properly
configured, the Rack PDU’s default setting (DHCP & BOOTP) for
BOOT Mode causes it to discover the BOOTP server.
1. Enter the Rack PDU’s MAC and IP addresses, the subnet mask and
default gateway settings, and an optional bootup file name in the
BOOTPTAB file of the BOOTP server.
2. When the Rack PDU reboots, the BOOTP server provides it with
the TCP/IP settings.
– If you specified a bootup file name, the Rack PDU attempts to
transfer that file from the BOOTP server using TFTP or FTP.
The Rack PDU assumes all settings specified in the bootup file.
– If you did not specify a bootup file name, the Rack PDU can be
configured remotely by using Telnet or by using the Web
interface: user name and password are both apc, by default. See
“Remote access to the control console” on page 11 for
configuration instructions.
If a BOOTP server is unavailable, see “APC Management
Card Wizard” on page 8, “Local access to the control
console” on page 11, or “Remote access to the control
console” on page 11 to configure TCP/IP settings.
Note
The MAC address is on the bottom of the Rack PDU and
on the Quality Assurance slip included in the package.

You must use the APC Management Card Wizard to
create the bootup file. To create a bootup file, see the
BOOTP section in the Addendum.

DHCP. You can use a RFC2131/RFC2132-compliant DHCP server to
configure the TCP/IP settings for the Rack PDU.
1. The Rack PDU sends a DHCP request that uses the following to
identify itself:
– Vendor Class Identifier (APC by default)
– Client Identifier (by default, the Rack PDU’s MAC address)
– User Class Identifier (by default, the identification of the Rack
PDU’s application firmware)
2. A properly configured DHCP server responds with a DHCP offer
that includes all of the settings that the Rack PDU needs for
network communication. The DHCP offer also includes the Vendor
Specific Information option (DHCP option 43). By default, the
Rack PDU ignores DHCP offers that do not encapsulate the APC
cookie in the Vendor Specific Information option using the
following hexidecimal format:
Option 43 = 01 04 31 41 50 43
where
– The first byte (01) is the code
– The second byte (04) is the length
– The remaining bytes (31 41 50 43) are the APC cookie

This section summarizes the Rack PDU communication
with a DHCP server. For more detail about how a DHCP
server is used to configure the network settings for the Rack
PDU, see “DHCP Configuration” in the User’s Guide.
S
ee also
See your DHCP server documentation to add code to
the Vendor Specific Information option.
To disable the APC cookie requirement you can use a local
computer. See “Local access to the control console” on
page 11. To change the control console’s DHCP Cookie Is
setting, an Advanced option in the TCP/IP menu, use
Telnet or another remote accessing method. See “Remote
access to the control console” on page 11.

Local access to the
control console
You can use a local computer to connect to the Rack PDU to access the
control console.
1. Select a serial port at the local computer, and disable any service
which uses that port.
2. Use the configuration cable (940-0144) to connect the selected port
to the serial port on the front panel of the Rack PDU.
3. Run a terminal program (such as HyperTerminal) and configure
the selected port for 9600 bps, 8 data bits, no parity, 1 stop bit, and
no flow control, and save the changes.
4. Press ENTER to display the User Name prompt.
5. Use apc for the user name and password.
6. See “Control console” on page 12 to finish the configuration.
Remote access to the
control console
From any computer on the same subnet as the Rack PDU, you can use
ARP and Ping to assign an IP address to the Rack PDU, and then use
Telnet to access that Rack PDU’s control console and configure the
needed TCP/IP settings.
1. Use ARP to define an IP address for the Rack PDU, and use the
Rack PDU’s MAC address in the ARP command. For example, to
define an IP address of 156.205.14.141 for the Rack PDU that has
a MAC address of 00 c0 b7 63 9f 67, use one of the following
commands:
– Windows command format:
arp -s 156.205.14.141 00-c0-b7-63-9f-67
– LINUX command format:
arp -s 156.205.14.141 00:c0:b7:63:9f:67
2. Use Ping with a size of 113 bytes to assign the IP address defined
by the ARP command. For example:
– Windows command format:
ping 156.205.14.141 -l 113
– LINUX command format:
ping 156.205.14.141 -s 113
Note
After the Rack PDU has its IP address configured, you can
use Telnet, without first using ARP and Ping, to access that
Rack PDU.
Note
The MAC address is on the bottom of the Rack PDU and on
the Quality Assurance slip included in the package.

How to Access a Configured Rack PDU
Overview After the Rack PDU is running on your network, you can use the
interfaces summarized here to access the unit.
Web interface As your browser, you can use Microsoft® Internet Explorer 5.0 (and
higher) or Netscape® 4.0.8 (and higher, except Netscape 6.x) to access
the Management Card through its Web interface. Other commonly
available browsers also may work but have not been fully tested by
APC.
To use the Web browser to configure Rack PDU options or to view the
event log, you can use either of the following:
• The HTTP protocol (enabled by default), which provides
authentication by user name and password but no encryption.
• The HTTPS protocol, which provides extra security through
Secure Socket Layer (SSL) and encrypts user names, passwords,
and data being transmitted. It also provides authentication of
Network Management Cards by means of digital certificates.
To access the Web interface and configure the security of your device on
the network:
1. Address the Rack PDU by its IP address or DNS name (if
configured).
2. Enter the user name and password (by default, apc and apc for an
Administrator, or device and apc for a Device Manager).
3. Select and configure the type of security you want. (This option is
available only for Admininistrators.)
S

For more information on the interfaces, see the User’s
Guide, located on the supplied CD and on the APC Web
site: www.apc.com

ee also
See the chapter entitled “Security” in the User’s Guide
for information on choosing and setting up your network
security. Use the Web/SSL/TLS option of the Network
menu to enable or disable the HTTP or HTTPS protocols.

How to Access a Configured Rack PDU
14 Switched Rack PDU Installation and Quick Start
Telnet/SSH You can access the control console through Telnet or Secure SHell
(SSH), depending on which is enabled. An Administrator can enable
these access methods through the Telnet/SSH option of the Network
menu. By default, Telnet is enabled. Enabling SSH automatically
disables Telnet.
Telnet for basic access. Telnet provides the basic security of
authentication by user name and password, but not the high-security
benefits of encryption. To use Telnet to access a Rack PDU’s control
console from any computer on the same subnet:
1. At a command prompt, use the following command line, and press
ENTER:
telnet address
As address, use the Rack PDU’s IP address or DNS name (if
configured).
2. Enter the user name and password (by default, apc and apc for an
Administrator, or device and apc for a Device Manager).
SSH for high-security access. If you use the high security of SSL for
the Web interface, use Secure SHell (SSH) for access to the control
console. SSH encrypts user names, passwords, and transmitted data.
The interface, user accounts, and user access rights are the same whether
you access the control console through SSH or Telnet, but to use SSH,
you must first configure SSH and have an SSH client program installed
on your computer.
SNMP After you add the PowerNet MIB to a standard SNMP MIB browser,
you can use that browser for SNMP access to the Rack PDU. The
default read community name is public; the default read/write
community name is private.
S
ee also
See the User’s Guide for more information on configuring
and using SSH.
Note
If you enable SSL and SSH disable SNMP. Allowing SNMP
access compromises the high security environment of SSL
and SSH. Administrators can disable SNMP using the
SNMP option of the Network menu.

Switched Rack PDU Installation and Quick Start 15
FTP/SCP You can use FTP (enabled by default) or Secure CoPy (SCP) to transfer
new firmware to the Rack PDU, or to access a copy of the Rack PDU’s
event logs. SCP provides the higher security of encrypted data
transmission and is automatically enabled when you enable SSH.
To access the Rack PDU through FTP or SCP, the default user name and
password are apc and apc for an Administrator, or device and apc for a
Device Manager. In the command line, use the IP address of the unit.
Note
If you enable SSL and SSH, disable FTP. Allowing file
transfers using FTP compromises the high security
environment of SSL and SSH. Administrators can disable
FTP using the FTP Server option of the Network menu.

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

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 and infants), anesthesia ventilators,
