These cards are hot swappable.
IMPORTANT:
•
Before installing a card in the chassis, make sure the connectors on the card are not broken or
blocked to avoid damaging the backplane.
•
To ensure good ventilation, install a filler panel in an empty slot.
•
Before you install a card that has a protection box, remove the protection box from the card as
follows:
a. Loosen the captive screws that secure the card to the protection box.
b. Pull the ejector levers of the card outwards.
c. Pull the card out of the protection box.
To install a card:
1. Wear an ESD wrist strap, and make sure it has good skin contact and is reliably grounded. For
more information, see "
Attaching an ESD wrist strap ."
2. Remove the filler panel (if any) from the slot to be used. Keep the filler panel secure for future
use.
3. Rotate out the ejector levers on the card.
4. Hold the card by the front panel with one hand and support the card bottom with the other (do
not touch its circuit). Slide the card steadily into the slot along the guide rails until you cannot
push the card further.
5. Rotate in the ejector levers on the card.
6. Fasten the captive screws on the card.

In case of dual grid inputs, make sure the amplitude, phase, and frequency of the input voltage of
the two grids are the same.
•
Provide a circuit breaker for each power module.
