Caution – It is critical that careful handling and seating of the carrier plate is
maintained during the insertion process. It is imperative that the simultaneous
insertion of the ejector screws be followed to avoid damage to the Sun Fireplane
interconnect connectors.
When inserting a carrier plate into the card cage:
Caution – Extreme caution must be used when inserting the board set into the
card cage of the Sun Fire E25K/E20K systems. The top-right leading edge of the
board set must be aligned properly in the card guide before insertion into the
system to prevent any component parts from being damaged if hit by the edge of
the carrier plate which can result in catastrophic failures to the system operation.
1. Hold the bottom edge of the carrier plate horizontally parallel and vertically
perpendicular with the top and bottom of the card cage and insert the bottom
edge into the bottom of the card guide, aligning with the top card guide avoiding
any angled insertion of the carrier plate (
