LEDs on the rear M.2 interposer
Figure 25. Rear M.2 interposer LEDs
The normal status of the LEDs on the interposer is that activity LED blinks and status LED remains off.
LED Status and description
1 Activity LED
(green)
On: The M.2 drive is idle.
“Off: The M.2 drive appears de-asserted.” on page 46
Blinking (about four flashes per second): The I/O activity of the M.2 drive is in progress.
2 Status LED
(yellow)
On: A drive fault occurs.
Off: The M.2 drive is working normally.
Fast blinking (about four flashes per second): The M.2 drive is being located.
Slow blinking (about one flash per second): The M.2 drive is being rebuilt.
Rear M.2 drive de-asserted problem
1. Hot-swap the two side-by-side M.2 drive assemblies with each other to see if the problem persists.
2. If the problem persists:
• Scenario 1: activity LED remains off, replace the interposer. If replacing interposers does not work, it
can be a power or PSoC fault, collect FFDC file and contact Lenovo Support.
