Preparing the terminal for new interface cards
To prepare the terminal for a new interface card:
1.
Remove the terminal from service by first switching off the terminal power. For an AC powered
terminal, remove the AC power connector. For a DC powered terminal, switch off the DC circuit
breaker or supply fuse.
2.
Remove all other cables from the terminal, marking their locations first, if necessary, to aid later
restoration. The safety earth connection must be the last cable removed.
3.
Ensure you have unobstructed access to the top and front of the terminal. Remove the terminal
from the equipment rack, if required.
4.
Remove the top cover of the terminal by removing two socket screws from the rear.
Note: The top cover slides back towards the rear of the chassis.
5.
Remove the front fascia by removing the four front panel socket screws.
Note: The front fascia first hinges out to clear the antenna connector and earth stud, and is then
removed by unclipping from the chassis and sliding downwards. See illustration below.
