Enable/Disable Switch; Led - Nortel Meridian 1 General Maintenance Information

Enable/disable switch

Some cards have a switch on the faceplate that enables or disables the
hardware for that card.
When you remove a card, whenever possible disable the software; then,
disable the hardware by setting the switch to Dis.
Hardware disable a card (set the switch to Dis) before you install it. After the
card is locked into position, set the switch to Enb; then enable the card in
software. Software disable and enable cards as described in the X11
Administration (553-3001-311).
Figure 4 on page 30 shows the typical location of an Enable/Disable
(ENB/DIS) switch.

LED

Many cards have one or more light emitting diodes (LEDs) on the faceplate.
The LED gives a visual indication of the status of the card or of a unit on a
card.
When a green LED is steadily lit, it indicates the card is operating normally.
When a green LED is off, it indicates the card is disabled or faulty.
When a red LED is steadily lit, it indicates the card, or a unit on it, is disabled
or faulty or unequipped. When a red LED is off and power is available to the
card, it indicates the card is operating normally.
Note 1: The shape of the LED (some are round and some are
rectangular) does not indicate a different function.
Note 2: In Options 61C, 81, and 81C, the red LEDs on the NT6D65
Core to Network Interface (CNI) Cards are lit when the associated Core
is inactive. This is normal operation.
