Used to find if input is present or not.

17

-48A ACB voltage

128

CPLD State

Discrete (0x6f), "OEM reserved" (0xde)

CPLD state sensor:

• 0002h - Local Healthy
• 0004h - Switchover Request Local
• 0010h - Switchover Status LED 1
• 0200h - Remote Healthy (Status of other ShMM; 1 = healthy, 0 = not healthy)
• 1000h - Local Presence (Status of ShMM; 1 = connected, 0 = not connected)
• 2000h - Active

Events generated when ShMM CPLD state changes (including redundancy state changes).

129

Reboot Reason

OEM Reserved (0xdd)

The state mask for the sensor indicates the cause of the last reboot. (The sensor reading is always 0 and does not have any meaning.)

• [1] The reboot was caused by a switchover operation.
• [2] The reboot was caused by a forced switchover operation.
• [3] The reboot was caused by the CLI command terminate.
• [4] The reboot was caused by loss of the HEALTHY bit.
• [5] The reboot was caused by loss of the ACTIVE bit.
• [6] The reboot of the Backup ShMM happened because the redundancy connection was broken but the Active ShMM was still alive.
• [7] The reboot happened due to an error during the Shelf Manager startup.
• [8] The reboot was caused by the ShMM hardware watchdog.
• [9] The reboot was initiated by software (a reboot() system call).
• [10] The ShMM has been power cycled.
