a card replacement. Card replacement should be performed when the card is
idle.
If the defective expansion card is on the far right of the Meridian Companion
set of cards, it can simply be removed and replaced with a new card. If the card
is in the middle of the card set, replace it by following these steps:
1. Disable the card from the Meridian 1 system and the Meridian
Companion system.
2. Open the door of the IPE or CE/PE Module or expansion cabinet.

Do not touch the printed circuit board or the
connector. The printed circuit board is a static-
sensitive device.
WARNING!
Each maintenance cable has a left plug and
a right plug. Switching the plugs will disable
the Meridian Companion system.
