LCD Unit
The LCD unit consists of an LCD display panel, push button, and shelf-level LED indicators on the NCS
2006 system. A backup flash memory is fitted into the LCD unit to support the database (DB) and image
backup in the operation of the NCS 2006.
The shelf controller card (TSC, TSCE, TNC, or TNCE) powers the 16 x 2 character LCD screen. The LCD
screen displays the shelf name, shelf IP address, and software version currently used. The LCD screen also
provides slot-level and port-level information of all card slots, including the number of critical, major, and
minor alarms. The display contrast is automatically adjusted for a clearer view. The three accessible push
buttons (SLOT, STATUS, and PORT) on the LCD unit are used to set parameters at the slot-level and port-level.
There are three alarm LEDs (CRIT, MAJ, and MIN) on the LCD unit that indicate whether a critical, major,
or minor alarm is present anywhere on the NCS 2006 shelf. The shelf controller card controls the conditions
that result in triggering the LEDs. The LEDs can be overwritten by the shelf controller card (TNC, TNCE,
TSC, or TSCE) in all the three states (OFF/red/green). The LCD unit supports the lamp test procedure and
the LEDs changes its color or state.
Note If the LCD unit is removed from the shelf, wait for at least 5 seconds before plugging it back into the
shelf. In the event the LCD display appears blank, remove the unit from the shelf, wait for at least 5 seconds
and reinsert the unit into the shelf.
The LCD module must be present in the NCS 2006 shelf to:
• Provision the ECU module, fan-tray assembly, or power modules.
• Retrieve alarms from the ECU module, fan-tray assembly, or power modules.

While replacing the power modules, do not provision or install any line cards when the NCS 2006
chassis is in the mixed power mode. Card provisioning and installation must be done only after both
the slots have the same type of power modules.
