DCE server administration settings

Automatically schedule or manually create backup files for your server's configuration data, or its configuration and repository data, and use a backup file to manually restore the server data, if needed. Note: If a server backup fails, an email is sent to the Data Center Expert Administrator users that include an email address as part of their user credentials.   Backup entries are listed by Destination Server, with information about each entry.   Backup Type: what data will be saved in backup files:   Full: all server data (configuration and repository) will be saved in every backup file.   Synchronized: only changes to server data (configuration and repository) will be saved after the initial backup file.   Configuration: only server configuration data will be saved in every backup file. You can add a backup to the list, or edit, remove, or manually start the backup entry selected in the list. Click Stop Backup to stop a manually-started backup. An backup-cancelled email will be sent to the Data Center Expert Administrators that include an e-mail address as part of their user credentials.   CIFS (Windows) mounts do not work when FIPS mode is enabled. MD5 authentication is required for CIFS, which is not supported in FIPS mode. FIPS mode is supported in DCE 8.2.0 and newer.

Define the settings the server uses to communicate on its public and private local area networks (LANs), and the settings used while discovering devices on the private LAN. The server is not a multi-homed server.   Note: To apply changes in the Public LAN1 or Private LAN2 tabs, you must click OK when asked if you want to restart the server. You can log on after the server finishes rebooting, which can take a few minutes.   Private (LAN2) tab   Private (LAN2) DHCP Discovery tab   Define settings the server will use when discovering SNMPv1 devices, or devices that use the APC DCal1 protocol, on its private Dynamic Host Configuration Protocol (DHCP) LAN, Network A.   Note: Changes are applied without a Data Center Expert server reboot.   Private Discovery Settings   Enable Private DHCP Discovery: Select to enable the Data Center Expert server to automatically discover any SNMPv1 devices, or devices that use the APC DCal1 protocol, on the private network. All other private network devices can be discovered by a device discovery process that searches the private network's IP addresses.   Read Community Name: Define the name to be used to discover SNMPv1 devices (public is the default).   Trap Registration   On Discovery, Register for Priority Scanning (SNMP Trap Directed Polling): select to register the Data Center Expert server as a trap receiver at a selected APC SNMPv1 device. This allows for faster reporting of errors at that device by the server: as a trap receiver, the server will poll the device as soon as it receives an SNMPv1 trap from that device; as a non-trap receiver, the server reports device alarms during normal scan intervals only.   Note: Only APC SNMPv1 devices discovered after this option is selected have the Data Center Expert server registered as a trap receiver.   Write Community Name: define the name that can be used to register the Data Center Expert server as a trap receiver at discovered APC SNMPv1 devices (private is the default).   Reset APC Devices   Click to reset private LAN APC devices, on Network A only, to use new IP addresses.   Note: The Write Community Name is used to reset the APC devices.   Private (LAN2) Network A tab   Define the settings the server will use to communicate on the private LAN, the port for which is labeled 2 on the server.   Note: Changes are applied only in response to a Data Center Expert server reboot.   When Reset APC Devices is selected on the DHCP Discovery tab, only the devices on Network A, defined by the Data Center Expert server IP address and subnet mask, will be reset.   The Data Center Expert server is not a multihomed server. The private LAN (LAN2) is a private network used to communicate with devices monitored by the Data Center Expert server only. Integration with other network configurations, such as routing to a public LAN or redundant links, is not supported.   IP Address: The private network address of the Data Center Expert server.   Subnet Mask: The TCP/IP subnet address for the local network segment. When Enable Private DHCP LAN is selected, the Subnet Mask selection defines this address; otherwise, type in the subnet mask's IP address.   Enable DHCP on Network A: Select to use the Data Center Expert server as a Dynamic Host Configuration Protocol (DHCP) server for the devices on the private LAN, Network A, enabled by default.   Private LAN Settings   Starting and Ending IP Address: Define the range of IP addresses available to the DHCP LAN. The first two parts of the four-part IP addresses are defined by the IP Address value, while the last two parts are initially defined by the Subnet Mask selection. You can edit the last 2 IP address values, except you cannot increase the Ending IP Address value: Total available addresses changes to Invalid IP range if you do.   Subnet Mask: A list of subnet mask addresses, each providing a different Starting and Ending IP Address range.   Total Available Addresses: Identifies how many addresses are available, based on the Starting and Ending IP Address range.   Private LAN Time Settings via DHCP   Apply server time zone offset on Private LAN: Check the box to assign the Data Center Expert server's time zone offset to the devices on the private LAN.   Private (LAN2) Network B tab   Define the settings the server will use to communicate on the private LAN, the port labeled 2 on the server. Devices with static IP addresses can be discovered on Network B on the private LAN.   Note: Changes are applied only in response to a Data Center Expert server reboot.   When Reset APC Devices is selected on the DHCP Discovery tab, devices on private LAN Network B, defined by its IP address and subnet mask, will not be reset.   The Data Center Expert server is not a multihomed server. The private LAN (LAN2) is a private network used to communicate with devices monitored by the Data Center Expert server only. Integration with other network configurations, such as routing to a public LAN or redundant links, is not supported.   Enable Network B on Private LAN: Select to use Network B on the Data Center Expert server private LAN for devices with static IP addresses.   IP Address: The private network address of the Data Center Expert server private LAN Network B, 192.168.16.1 by default.   Subnet Mask: The TCP/IP subnet address for the private LAN network B segment, 255.255.255.0 by default; otherwise, type in the subnet mask's IP address.   Public (LAN1) tab   Define the settings the Data Center Expert server will use to communicate on the public LAN, the port for which is labeled 1 on the server.   Note: Changes are applied only in response to a Data Center Expert server reboot.

Define the settings the server must use to communicate through a proxy server.   A Data Center Expert server needs to use the internet to communicate with APC to download firmware updates, for example, or to communicate with the StruxureOn server.   Select Use Proxy to enable the proxy settings. Identify the hostname or IP address of the proxy server, the port the Data Center Expert server will use to communicate with the proxy server, and the username and password to access the proxy server.
