3.1.5 Help
DarkStar systems include a Help feature for all commands. To use this feature, enter
?
at any system prompt or command line.
Or, press tab at the end of incomplete commands.
3.1.6 Operating Modes
DXMOS offers two general operating modes: disabled and enabled. Disabled mode allows all users to display limited
information about a system. Enabled mode allows users with appropriate permission to reconfigure a system and display all
information about the system.
Configure mode is a particularly important subset of commands available in enabled mode. It is used to set up and manage
DarkStar systems and can be used to effect changes that impact customer traffic.
3.2 Configuration
3.2.1 Power-Up and Reboot
DarkStar systems boot when either of the two power supply modules are connected. DarkStar systems are designed for
continuous operation and therefore feature no power switch.
For IPv6 working, IPv6 addresses are assigned using IPv6 Stateless Address Autoconfiguration (see RFC 2462). This requires
that there be at least one IPv6 router accessible on the local link. The router should be configured so that the router adver-
tisement has the 'O' flag set and the 'M' flag cleared. The prefix-information option in the router advertisement should have
both the 'L' and 'A' flags set.
The side reset button shown in Figure 3.1 on page 22 cycles internal power and reloads software and gateware. Front-panel
LEDs display system status and can help to monitor this process. A comprehensive table of LED patterns and their meanings
can be found in LED Codes in Chapter 3 - Software.
To cycle power:
•
Use a non-conductive reset tool, such as the one provided with the system, to press and immediately release the side reset
button.
WARNING
!
Do not use a metal object (such as a paperclip) to depress the side reset button. Doing so
may expose the operator to hazardous voltage or damage the DarkStar system.
WARNING
!
Cycling power disrupts customer traffic. It should only be done if a system has crashed or
a hard reset of all hardware is desired.
