Readying the Cards

WarningBefore handling any cards, ground yourself by clipping the wrist strap that is supplied with

MGX 8220 shelf to a convenient metallic contact on the shelf and to your wrist. This simple procedure

prevents static electrical damage to the cards.

Systems may be shipped with empty slots with filler cards or with plug-in cards installed. If filler

cards are installed in any of the slots, they may need to be replaced with functional cards. Remove,

replace, and install front and back cards as necessary to obtain the correct configuration.

NoteBoth the front card and the back card of all card sets in the shelf must be present for proper

operation of the shelf.

If a back card is removed and reseated or changed for another back card, the associated front card

must be reset.

Removing and Installing the Front Cards

When seated, MGX 8220 front cards are retained by a mechanical latch attached to the card.

(See Figure7-21.)

until the latch springs open, approximately 10°. Continue to lift the insertion/extractor lever

to disconnect the connector.
