# Chassis Board table

Each boardEntry object in the Board table contains information about a single board in the chassis. This group of objects includes the board model, a textual description of the board model, a family identifier, the board's status, the trunk count, the board revision, the board's serial number, and the board's date of manufacture.

The boardIndex object, whose value is assigned by the NMS Chassis agent, identifies each boardEntry. New boardEntry objects are added to this table and configured for the OAM API when a board is added to the chassis.

If a board is physically extracted, entries in the Board table are removed. If a board is inserted, a new entry is added to the Board table using the next free index. Whenever a board is inserted or extracted, a trap is sent if traps are enabled.
