A cooling unit is On when the state is normal and in Standby when the state is not normal. Output State.
Cooling Group Configuration Use the cooling group configuration settings to add cooling units to the group and to define group operation. The system automatically assigns the state of Backup to units in the group. A unit whose Role Override setting is set to ON will automatically be set as a Primary cooling unit. A unit in the Standby or Failed state is not considered a potential backup unit. The system periodically reviews the state of the units to maintain the proper number of ON and Backup units.
Availability. Redundancy (Backup Units), Runtime Balancing and Load Assist modes are only supported in Spot, HACS and RACS configurations. • Backup Units: The display will show the range of units assigned to the backup function, for example: 1 - X. The cooling unit is not running but is ready to run if a unit fails, is unable to cool or needs cooling assistance. • Load Asst (Load Assist): Enabled/Disabled.
Control the Environment The primary function of the cooling unit is to capture the heat generated by IT equipment and neutralize it before it mixes with the room. The control strategies employed by the cooling unit depend upon the deployment strategy of the cooling group. In an in-row environment, the cooling unit supplies constant-temperature supply air to the common cold aisle. The fan speed is modulated to ensure that the required volume of air reaches the IT equipment.
PID settings Path: Main > Set Group PID The Proportional plus Integral plus Derivative (PID) loop controls the output of the fans. Caution: This procedure is to be performed by APC authorized personnel only. Improperly set PID controls could result in equipment damage. There are two sets of PID coefficients stored in the unit. One set is used when the unit is programmed for Spot (Proportional) mode and the other set is used when the cooling unit is programmed for InRow mode.
Tune the PID loop A qualified service technician must tune the PID loop to optimize the performance of the cooling group. Caution: This procedure must be performed by APC authorized personnel only. The PID loop must be tuned after the equipment in the room is installed and running. The loop should be tuned periodically to account for changes in the room load. 1. Adjust the integral and derivative constants to zero and the proportional constant to 1.0. 2.

Network Management Card Quick Configuration The cooling unit is shipped with a Network Management Card that enables the cooling unit to be managed over a network. Configure the Network Management Card to control this cooling unit through a network. Overview You must configure the following TCP/IP settings before the Network Management Card can operate on a network: • IP address of the Network Management Card • Subnet mask • Default gateway Caution: Never use the loopback address (127.0.0.
APC Device IP Configuration Wizard You can use the APC Device IP Configuration Wizard at a computer running Windows 2000, Windows Server 2003, or Windows XP to configure a Network Management Card. Note: Most software firewalls must be temporarily disabled for the Wizard to discover unconfigured Network Management Cards. To configure one or more Network Management Cards from a user configuration file, see the User’s Guide on the Utility CD. 1. Insert the Utility CD into a computer on your network. 2.
BOOTP. For the Network Management Card to use a BOOTP server to configure its TCP/IP settings, it must find a properly configured RFC951-compliant BOOTP server. 1. In the BOOTPTAB file of the BOOTP server, enter the MAC address of the Network Management Card, the IP addresses of the subnet mask, default gateway, and an optional bootup file name. For the MAC address, look on the nameplate of the InRow RD or on the Quality Assurance slip included in the package. 2.
DHCP. You can use a RFC2131/RFC2132-compliant DHCP server to configure the TCP/IP settings for the Network Management Card. This section summarizes communication between the Network Management Card and a DHCP server. For more detail about how a DHCP server can configure the network settings for a Network Management Card, see “DHCP Configuration” in the User’s Guide. 1.
Remote access to the control console From any computer on the same subnet as the Network Management Card, you can use ARP and Ping to assign an IP address to a Network Management Card, and then use Telnet to access the control console of that Network Management Card and configure the needed TCP/IP settings. Note: After the IP address of the Network Management Card is configured, you can use Telnet without first using ARP and Ping to access that Network Management Card. 1.
Control console After you log on at the control console, as described in“Local access to the control console” on page 30 or “Remote access to the control console” on page 31: 1. Choose Network from the Control Console menu. 2. Choose TCP/IP from the Network menu. 3. If you are not using a BOOTP or DHCP server to configure the TCP/IP settings, select the Boot Mode menu and then select Manual boot mode. 4. Set the System IP, Subnet Mask, and Default Gateway address values.
Access a Configured Network Management Card Overview After the Network Management Card is running on your network, you can access the configured Network Management Card through the following interfaces: • • • • • Web interface (HTTP or HTTPS protocol) Telnet or Secure SHell (SSH) SNMP FTP or Secure CoPy (SCP) to upgrade firmware Modbus For more information on the interfaces, see the User’s Guide. Web interface Use Microsoft® Internet Explorer® (IE) 5.
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 InRow RD’s control console: 1. At a command prompt, use the following command line, and press ENTER: telnet address As address, use the IP address of the Network Management Card 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 User).
Simple Network Management Protocol (SNMP) SNMPv1 only. After you add the PowerNet® MIB to a standard SNMP MIB browser, you can use that browser to access the Network Management Card. All user names, passwords, and community names for SNMP are transferred over the network as plain text. The default read community name is public; the default read/write community name is private. SNMPv3 only. For SNMP GETs, SETs, and trap receivers, SNMPv3 uses a system of user profiles to identify users.
Recover From a Lost Password You can use a local computer (a computer that connects to the Network Management Card through the serial port) to access the control console. 1. Select a serial port at the local computer, and disable any service that uses that port. 2. Connect the provided RS-232 configuration cable to the selected port on the computer and to the RS-232 console port at the Network Management Card. 3.
