3UPS Network Management Card 2 User’s Guide
Internal Management Features
Overview
Use the user 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.
For more information about the internal user interfaces, see “Web User Interface” on page 28 and
“Command Line Interface (CLI)” on page 8. See “SNMP” on page 58 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 Network Management Card. The priority for access, beginning with
the highest priority, is as follows:
1. Local access to the command line interface from a computer with a direct serial connection to the
Management Card
2. Telnet or SSH access to the command line interface from a remote computer
3. Web access, either directly or through InfraStruXure Central
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, and Read-Only User — and these are
protected by user name and password requirements.
• An Administrator can use all of the menus in the user interface and all of the commands in the
command line interface. The default user name and password are both apc.
• A Device User can access only the following:
– In the user interface, recent events on the Home tab; the menus on the UPS tab; and the menus of
the Logs tab including the event and data logs, accessible under the Events and Data headings.
(The event and data logs display no button for this user 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 apc.
• A Read-Only User has the following restricted access:
– Access through the user interface only.
– Access to the same tabs and menus as a Device User above, 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 for this user to clear
the log).
The default user name is readonly, and the default password is apc.
To set User Name and Password values for the three account types, see “Setting user access” on
page 51.
