Features of the InRow RC/RD/RP (600 mm) cooling unit

The American Power Conversion (APC®) InRow RC/RD/RP (600 mm) cooling unit is a modular air
conditioning unit that is available in either a direct expansion (DX) model (ACRD500 series or
ACRP100 series) or a chilled water (CW) model (ACRC500 series or ACRP500 series). It is the width
of a standard enclosure (600 mm), and can be placed in a data-center row. It provides full management
capabilities over a network using HyperText Transfer Protocol (HTTP), Telnet, HTTP over Secure
Sockets Layer (HTTPS), Secure Shell (SSH), Simple Network Management Protocol (SNMP), File
Transfer Protocol, (FTP), Secure CoPy (SCP), and Modbus. The cooling unit provides the following
features:
• Group c ontrol
• Temperature monitoring
• Remote shutdown
• Output contact monitoring
• Event log accessible by Telnet, FTP, SSH, SCP, serial connection, the display interface, or a Web
browser
• SNMP traps and e-mail notifications sent in response to events
• Syslog events sent to configured Syslog servers
• Security protocols for authentication and encryption

Initial setup

You must define the following three TCP/IP settings for the cooling unit before it can operate on the
network:
• IP address of the cooling unit
• Subnet mask
• IP address of the default gateway
Note: Never use the loopback address (127.0.0.1) as the default gateway address for
the cooling unit. Doing so will disable the unit and will require you to reset TCP/IP
settings to their defaults using a local serial login.
To use a DHCP server to configure the TCP/IP settings for a cooling unit, see “TCP/
IP settings” on page 37.
To configure the TCP/IP settings, see the Installation Manual for your cooling unit,
provided in printed form and in PDF on either the Utility CD or on the APC Web
site, www.apc.com.
