Installing equipment
1 Set jumpers on the following replacement cards the same as on the
card you removed:
NT8D14 Universal Trunk Card
NT8D15 E&M Trunk Card
To check settings, see Circuit Card: Installation and Testing (553-3001-211).
2 Insert the replacement card into the vacated slot and hook the locking
devices.

until the card is configured and enabled in software, then the LED goes
out. If the LED does not follow the pattern described or operates in any
other manner (such as continually flashing or remaining weakly lit),
replace the card.
