Product Description
Features
The two UPS Network Management Cards (NMC) mentioned below are web-based, IPv6 Ready products that manage supported devices using multiple open standards such as:
- Hypertext Transfer Protocol (HTTP).
- Simple Network Management Protocol versions 1 and 3 (SNMPv1, SNMPv3).
- File Transfer Protocol (FTP).
- Telnet
- Secure SHell (SSH).
- Hypertext Transfer Protocol over Secure Sockets Layer (HTTPS).
- Secure CoPy (SCP).
The Network Management Card:
- Provides UPS control and self-test scheduling features.
- Provides data and event logs.
- Supports using a Dynamic Host Configuration Protocol (DHCP) or BOOTstrap Protocol (BOOTP) server to provide the network (TCP/IP) values of the NMC.
- Enables you to configure notification through event logging (by the NMC and Syslog), e-mail, and SNMP traps. You can configure notification for single events or groups of events, based on the severity level or category of events.
- Provides export ability to a user configuration (.ini) file from a configured card to one or more unconfigured cards without converting the file to a binary file.
- Provides a selection of security protocols for authentication and encryption
The Network Management Card 2 includes all Network Management Card features and the following:
- Provides two USB ports.
- Supports two universal input/output ports, to which you can connect:
- Temperature or temperature/humidity sensors.
- Relay input/output connectors that support two input contacts and one output relay.
IPv4 Initial Set up
Define two TCP/IP settings for the NMC before the NMC can operate on the network:
- IP address of the NMC.
- IP address of the default gateway (only needed if you are going off segment).
| NOTICE |
|---|
Do not use the loopback address (127.0.0.1) as the default gateway. Doing so disables the card. Then log on using a serial connection and reset the TCP/IP settings to the defaults. |
ReferenceFor detailed information on how to use a DHCP server to configure the TCP/IP settings at an NMC, see the "TCP/IP and Communication Settings" section in the, "Administration:Network Features" chapter of this manual.
IPv6 Initial Set up
IPv6 network configuration provides flexibility to accommodate the user requirements. Use the device "IP Configuration Wizard" for initial setup.
Network Management Features
These applications and utilities work with a UPS that connects to the network through an NMC.
Network Shutdown Utility - Provide unattended remote graceful shutdown of computers that are connected to UPSs
Management Information Base (MIB) with a standard MIB browser - Perform SNMP, SETs, and GETs and use SNMP traps
Device IP Configuration Wizard - Configure the basic settings of one or more NMCs over the network
Security Wizard - Create components needed for high security for the NMC when you are using Secure Sockets Layer (SSL) and related protocols and encryption routines
Internal Management Features
Overview
Use the web interface or the command-line interface to view the status of the UPS and manage the UPS and the NMC. You can also use SNMP to monitor the status of the UPS.
ReferenceFor more information about the internal user interfaces, see the, "Web Interface" chapter and the, "Command Line Interface" chapter in this manual. See the "SNMP" section in the, "Administration:Network Features" chapter for information about how SNMP access to the NMC is controlled.
Access Priority for Logging On
Only one user at a time can log on to the management card. The priority for access, beginning with the highest priority, is as follows:
- Local access to the command-line interface from a computer with a direct serial connection to the management card
- Telnet or SSH access to the command-line interface from a remote computer
Note: SNMP has Write + and Write access. Write + has top access and enables logging on when another user is already logged on. Write access is equivalent to web access.
Types of User Accounts
The NMC has three levels of access:
- Administrator
- Device User
- Read-Only User
All of which are protected by user name and password requirements.
- An Administrator can use all of the menus in the web interface and all of the commands in the command-line interface.
- A Device User can access only the following:
- In the web interface, the menus on the UPS tab and the event and data logs, accessible under the Events and Data headings on the left navigation menu of the Logs tab. The event and data logs display no button to clear the log.
- In the command-line interface, the equivalent features and options
The default user name is device, and the default password is cat.
- A Read-Only User has the following restricted access:
- Access through the web interface only.
- Access to the same tabs and menus as a Device User, but without the capability to change configurations, control devices, delete data, or use file transfer options. Links to configuration options are visible but disabled. The event and data logs display no button to clear the log.
The default user name is read-only, and the default password is cat.
ReferenceTo set User Name and Password values for the three account types, see the "Setting User Access" section in the, "Administration: Security" chapter of this manual.
How to Recover from a Lost Password
You can use a local computer that connects to the management card through the serial port to access the command-line interface.
- Select a serial port at the local computer, and disable any service that uses that port.
- Connect the provided serial cable to the selected port at the computer and to the configuration port at the management card.
- Run a terminal program and configure the selected port for 9600 bps, 8 data bits, no parity, 1 stop bit, and no flow control.
- Press "ENTER", repeatedly if necessary, to display the User Name prompt. If you are unable to display the User Name prompt, verify the following:
- The serial port is not in use by another application.
- The terminal settings are correct as specified in step 3.
- The correct cable is being used as specified in step 2.
- Press the "Reset" button. The Status LED will flash alternately orange and green. Press the "Reset" button a second time immediately while the LED is flashing to reset the user name and password to the defaults temporarily.
- Press "ENTER", repeatedly if necessary, to display the User Name prompt again, then use the default, cat, for the user name and password. (If you take longer than 30 seconds to log on after the User Name prompt is redisplayed, you must repeat step 5 and log on again.)
- At the command-line interface, use the following commands to change the User Name and Password settings, both of which are now cat:
user -an yourAdministratorName
user -ap yourAdministratorPassword
For example, to change the Administrator user name to Admin, type:
user -an Admin
- Type "quit" or "exit" to log off, reconnect any serial cable you disconnected, and restart any service you disabled.

Watchdog Features
Overview
To detect internal problems and recover from unanticipated inputs, the management card uses internal, system-wide watchdog mechanisms. When the NMC starts to recover from an internal problem, a System: Warmstart event is recorded in the event log.
Network Interface Watchdog Mechanism
The management card implements internal watchdog mechanisms to protect from becoming inaccessible over the network. For example, if the management card does not receive any network traffic for 9.5 minutes (either direct traffic, such as SNMP, or broadcast traffic, such as an Address Resolution Protocol [ARP] request), the NMC assumes that there is a problem with the network interface and restarts.
Resetting the Network Timer
To ensure that the management card does not restart if the network is quiet for 9.5 minutes, the management card attempts to contact the default gateway every 4.5 minutes. If the gateway is present, the gateway responds to the management card, and that response restarts the 9.5-minute timer. If your application does not require or have a gateway, specify the IP address of a computer that is running on the network and is on the same subnet. The network traffic of that computer will restart the 9.5-minute timer frequently enough to prevent the management card from restarting.
