When you install the sLB-1024 boards, start at the bottom of the chassis and work your way up
to avoid friction between components of adjacent boards.
These tips can assist you to insert boards into the chassis.
•
The ejectors have an integrated guide pin that slides into a groove in the chassis.
You may experience difficulty in locking the ejector handles in place if the guide pin
is not perfectly aligned with the groove. When this occurs, try to jiggle the ejector
handle until it locks into place.
•
It is recommended to tighten the screws in a "criss-cross" sequence (top right, bot-
tom left, top left, and then bottom right.)
•
When inserting the screws, make sure that they are inserted directly into their
groove, and that they slide in easily. It is recommended to start the insertion manu-
ally, to ensure that the insertion is correct.
When using a drill-like electric screwdriver to fasten the board screws in place, do not
use more than Torque 3 force (10 lb. in) as this could damage the screws.

Extracting/Inserting Boards
Line boards (sLBs), fabric boards (sFBs), and management boards (sMBEs) have a pair of ejectors
that lock the board in place and serve as a lever for seating or extracting.
When handling electronic boards, wear grounding wrist straps to avoid ESD damage to
the card. To avoid electric shock, do not touch the mid-plane with your bare hands or
any metal tool.
On each module, the blue hot-swap LED indicates when the board is ready to be removed from the
chassis.
The ejectors snap inward to lock the board into place and may include a red button to disengage
the lock and electrically notify the system that an extraction has been requested.
