What are the full steps and proper order for removing the motherboard tray from the chassis of the SYS-421GE-TNHR2-LCC system?
A.
Pull down on the latches until the latches release completely > Slowly start pulling the tray out > Release the safety latches on both sides
B.
Loosen 12 screws on both ends of the front of the chassis to loosen the latches > Slowly start pulling the tray out > Continue pulling out the tray the rest of the way
C.
Loosen 8 screws on both ends of the front of the chassis to loosen the latches > Continue pulling out the tray the rest of the way
D.
Loosen 2 screws on both ends of the front of the chassis to loosen the latches > Pull down on the latches until the latches release completely > Slowly start pulling the tray out > Release the safety latches on both sides > Lift and move the quick connect cables out of the way > Continue pulling out the tray the rest of the way
Removing the motherboard tray from the SYS-421GE-TNHR2-LCC involves:
Loosen 2 screws on both ends of the front of the chassis: Secures latches, per Supermicro’s design (e.g., SYS-420GP-TNAR).
Pull down on the latches until they release completely: Frees the tray.
Slowly start pulling the tray out: Initiates removal.
Release the safety latches on both sides: Prevents dropping (DLC safety feature).
Lift and move the quick connect cables: Clears DLC coolant or power lines.
Continue pulling out the tray: Completes removal.Option D is the most comprehensive, matching Supermicro’s DLC system protocols. A skips screws and cables, B (12 screws) and C (8 screws) exaggerate screw count, lacking safety steps. D ensures safe, complete removal.References:Supermicro motherboard tray removal guides, DLC system safety features.
