Holding Switch Fabric Boards
While removing an SFB from the router chassis, you should hold the SFB vertically until it is clear of the
router chassis. Then you should rotate the SFB 90 degrees and place it on an antistatic mat or in an
electrostatic bag for storage (see Figure 143 on page 246).
Figure 143: SFB
The proper method of holding an SFB is to:
1. Hold the SFB by the ejectors while you keep the SFB vertical, and slide the SFB about three-quarters
of the way out of the chassis.
2. Place one hand underneath the SFB to support it, and slide it completely out of the chassis.
CAUTION: Never hold an SFB by the connector edge. The connectors are fragile.
You cannot align and seat an SFB properly if the connectors are damaged.
