Update via Web interface
To update the NMC via the web interface, key in the kernel and file system image names and make sure those
files are available from a TFTP server. Click the "Set Parameter" button. To update the kernel click the "Flash
Kernel" button. To update the filesystem click the "Flash File System" button.
Image upload may fail due to memory fragmentation. In this case it is necessary to reboot the NMC before
performing an update. Click the " NMC Reboot" button. Upgrading or rebooting the NMC will not affect any card
transmissions.
Cards can also be upgraded online. Click the "Upgrade Line Card" button. More details are in the appendix for
each particular card. The update image for the card must also be on the TFTP server.
Time and Date Setting
The NMC supports time setting manually, by syncing to PC's clock or by SNTP network time protocol. To setup
the unit for automatic time adjustment, enter the IP address of the Time Server, adjust the time zone offset, enable
the 'automatic time adjustment' and then click the 'Set Parameters' button. Next click 'Sync. with NTP' button. The
'Current Date and Time' should now match the network Time Server's time.
Parameter Management
Parameter settings may be backed up off unit to a configuration file. This file can be used to restore settings
later or to copy to other racks with same configuration. There is also parameter copy/paste function to copy chassis
to chassis, slot to slot and local to remote.
3.2.2.4 System / Local Area
" Local Area " will display a graphic representation of all the cards inserted in the chassis and the real-time
status of all LEDs (this display is also the default 'Home' page of the web interface).
Link states are shown with green LEDs. Flashing LEDs also indicate that there is traffic on the interface. Alarm
LEDs are shown in RED. When any loop back test is being performed, the 'LB Test' LED will also be shown in RED.
When a 'Power' LED is not lit, it indicates that this converter has been disabled through software. You can click
on any card and be taken directly to its management page. Please refer to Appendix A for all the detailed
operation of the individual cards.
The graphic indicators at the bottom of the display show the real time status of the two Power Modules and the
two chassis fans. An error in any of these will result in the effected icon's LED blinking in RED.
