Holding Line Cards and Control Boards
Pay proper attention to the way you are holding line cards and RCBs. Line cards and RCBs are installed
horizontally and it is best to hold them by the sides of the units when they are not in the chassis.
When walking with a line card or RCB:
1. Orient the line card or the RCB so that the faceplate is toward you.
2. Grasp each side of the unit firmly as you slide the unit out of the chassis.
3. Take care not to strike the unit against any object as you carry it.
CAUTION: Never hold the line card or RCB by the connector edge. The connectors
are fragile and the line card or RCB will not seat properly if the connector is damaged.
See Figure 187 on page 322.

4. If you must rest a line card or control board on an edge, place a cushion between the edge and the
surface.
CAUTION: Do not stack line cards or RCBs on top of one another or on top of any
other component.
5. Place each line card separately in an electrostatic bag or on an antistatic mat placed on a flat, stable
surface.
