Installing an Expansion Card
The ECN main board includes two types of slots: system slots and expansion
slots. System slots contain system cards that are installed in the factory and
provide basic or pre-installed optional functionality for the ECN. Expansion slots
contain expansion cards that are generally installed before field deployment
(although some expansion cards can be factory installed) and provide additional
functionality for the ECN. For example, an expansion card can add a modem for
additional communications functionality.
There are six expansion slots (numbered 1 to 6), and five types of expansion card,
types A, B, C, D, and E. Each of these types has different electrical and
mechanical characteristics based on the type of functionality it is designed to
provide. See the Edge Control Node 7000 Series Expansion Card Developer’s
Guide for more information about each of the card types.
Important: The ECN hardware, operating system, and communications
software does not support plug and play or hot plug of expansion cards. Power
must be removed from the ECN before installing, or uninstalling, an expansion
card.
Installation for Card Types A and B
Access to expansion slots 1 and 2 can be made while the card cage is installed in
the outer enclosure:
1. Remove the enclosure cover
2. Remove the inner card cage cover
3. Remove the card retainer
Card guides are made available for each slot, which (along with the alignment
holes in the ECN main board) prevent expansion cards from being misaligned on
