Preliminary Information
Features of the
American Power Conversion’s MasterSwitch™ Power
Distribution Unit (PDU) is a stand-alone, network-manageable
device that allows programmable control of eight power
outlets. MasterSwitch models AP9211 and AP9217 have
NEMA 5-15 outlets. MasterSwitch models AP9212 and AP9218
have IEC-320 C13 outlets.
You can remotely control a MasterSwitch PDU through its
Web, SNMP, or Control Console network interfaces.
Both MasterSwitch models have these additional features:
• For each outlet, independent control of the following:
– Power On Delay
– Power Off Delay
– Reboot Duration
• Power-up sequencing
• 16 independent Outlet User accounts
• Basic and MD5 authentication for password security.
• Three levels of user access accounts:
– Administrator
– Device Manager
– Outlet User
• An auto-configuration utility that you can use to create a
configuration file, which you can then download to
other MasterSwitch PDUs, individually or as a group.

• An event log that you can display through the Control
Console or Web interface to import into a spreadsheet
• Compact design that requires only one U of rack space.
• The ability to upgrade MasterSwitch firmware without
affecting outlet state.
Note: The MasterSwitch PDU does not provide power
protection. Therefore, APC does not recommend
plugging a unit directly into any unprotected
power source, such as a wall outlet.
The MasterSwitch PDU is shipped with the following items:
• A pre-installed Web/SNMP Management SmartSlot
• A null-modem cable
• A CD-ROM containing product documentation and the
Management Card Wizard
• Rack-mount brackets and self-tapping Phillips screws
• This Installation and Quick Start Manual
• A warranty registration card

The shipping materials are recyclable. Save them for later
reuse, or dispose of them properly.
Installing MasterSwitch
Mounting in a
You can place the MasterSwitch PDU on a desktop or mount it
in an enclosure. The procedure below instructs how to mount
the unit in an APC NetShelter® Premium enclosure. You can
also mount the unit into other EIA-310-D standard 19-inch
! Remove the rubber feet from the bottom of the unit.
" Attach the mounting brackets to the unit, using the two selftapping Phillips screws provided for each bracket.

Mounting in a
# Choose a location that will occupy one U of space in the
enclosure. (A notched hole on the vertical rail denotes the
middle of a U-space.)
$ Install a caged nut (provided with the enclosure) above and
below a notched mounting hole on each vertical mounting rail.
% Align the mounting holes of the brackets with the installed
caged nuts. Insert and tighten the screws.
Quick Configuration
You must configure the following network settings for the
MasterSwitch PDU before it can operate on a network:
• IP address of the MasterSwitch PDU
• Subnet Mask
• IP address of the default gateway
After you configure MasterSwitch network settings, no further
configuration is required. The remaining MasterSwitch
properties are pre-configured at the factory. However, you may
want to customize these properties for your application. See
“Managing the MasterSwitch PDU” in the User’s Guide on the
enclosed CD for more information.

• If you are using Windows 95, Windows 98, or Windows
NT, see “Through the Management Card Wizard” on
page 5.
• If you are not using a Windows-based operating system
or if you require direct serial configuration, see “Serially
through the Control Console” on page 6.
• If you are a network administrator using Address
Resolution Protocol (ARP), see “Over the Network by
ARP” on page 7
• If you are a network administrator using BOOTP, see
“Over the Network by BOOTP” on page 7.
Through the Management Card Wizard. On Windows 95,
Windows 98, or version 4.0 of Windows NT, use the
Management Card Wizard to configure all attributes quickly,
including TCP/IP settings, for the pre-installed Management
Card. Use the CD-ROM supplied with the MasterSwitch PDU
and follow the on-screen instructions.
The pre-installed Management card provides the network
interface for the MasterSwitch PDU.

TCP/IP settings,
Serially through the Control Console. If you are not using a
Windows platform, or you require direct serial configuration,
use the Serial Console port to configure the TCP/IP settings for
the Management Card, as follows:
1. Connect the supplied null-modem cable (APC part
number 940-0103) to an available serial port on your
computer and to the serial port on the front panel of the
MasterSwitch unit.
2. Disable PowerChute Plus, UNIX Respond, or other
service that may be using the serial port on the
3. Run a terminal emulator such as Windows
HyperTerminal. Configure the appropriate serial port
with the following settings: 2400 bps, no parity, 8 data
bits, 1 stop bit, and no flow control.
Note: Some terminal emulators, such as
HyperTerminal, require that you disconnect and
reconnect in order for the new serial settings to
take effect.
4. From your computer, press ENTER until the user name
prompt appears.
5. Enter the default user name and password: apc in
6. On the Main menu, choose Network.
7. From the Network menu, choose TCP/IP.
8. Within the TCP/IP menu do the following:
a. Disable BOOTP, and accept changes.
b. Set a valid IP address, Subnet Mask and default
gateway for your network, and accept changes.
c. Press ESC until the Main menu appears, then select
Note: The new settings take effect when you log out.

TCP/IP settings,
Over the Network by ARP. To configure the TCP/IP settings
of the MasterSwitch PDU using Address Resolution Protocol
(ARP), perform the following steps:
1. Set up the unit and connect it to the network.
2. From a command prompt on a computer connected to
the local subnet, type arp -s ip_addr_card
mac_card. For example:
arp -s 00-c0-b7-78-ad-90
Note: To obtain the MAC address, see the Quality
Assurance slip, look on the bottom of the unit, or
select the TCP/IP menu from the Control
3. Type telnet ip_addr. See the example below:
The default user name and password are both apc. Configure
the correct Subnet Mask and default gateway in the TCP/IP
section of the Network menu.
Over the Network by BOOTP. BOOTP is enabled by default.
Use a BOOTP server to configure MasterSwitch TCP/IP
settings and to perform the following steps:
1. Enter the MasterSwitch MAC address, IP address,
subnet mask, default gateway and optional boot-up file
Note: To obtain the MAC address, see the Quality
Assurance slip, look on the bottom of the unit, or
select the TCP/IP menu from the Control

TCP/IP settings,
2. The BOOTP server provides network settings to the
MasterSwitch PDU. If a boot-up file name was
specified, the MasterSwitch PDU attempts to transfer
that file from a TFTP or FTP server on the same
computer as the BOOTP server. The MasterSwitch
assumes all settings specified in the boot-up file.
Note: You must use the Management Card
Configuration Wizard to create the boot-up file.
Alternatively, you can configure the MasterSwitch PDU
remotely using the Telnet, Web, or SNMP interface.
Accessing the
You can access the MasterSwitch PDU through a Web browser,
Telnet, or SNMP interface, as described below.
Through a Web browser. Perform the following steps:
1. From your Web browser, enter the System IP address of
the MasterSwitch PDU, or enter its DNS name (if a DNS
name is configured).
2. Log on to the MasterSwitch PDU, using the default User
Name and Password apc (lowercase).
Through Telnet. Perform the following steps:
1. From your Telnet session, enter the System IP address
of the MasterSwitch PDU.
2. Log on to the MasterSwitch PDU, using the default User
Name and Password apc (lowercase).
Through an SNMP interface. Accessing the MasterSwitch
PDU using SNMP requires a Network Management Station,
running management software such as HP OpenView. The
default read-only community name is public. The default
read/write community name is private.
