Bismillah...
kemarin salah satu server kami (server HP Ml350 G5) tidak bisa booting setelah lama tidak di hidupkan , salah satu indikator led menyala dengan warna mearah berkedip (flashing) ,

berikut informasi  HP ProLiant ML370 G5 Server - LEDs and Buttons

Systems Insight Display LEDs

To view a quick reference for component identification and status, access the Systems Insight Display.

Item	Description	Status
1	Primary power supply LED	Amber = Failure Off = Normal
2	Redundant power supply LED	Amber = Failure Off = Normal
3	Online spare memory LED	Green = Protection enabled Amber = Memory failure occurred Flashing amber = Memory configuration error Off = No protection
4	Mirrored memory LED	Green = Protection enabled Amber = Memory failure occurred Flashing amber = Memory configuration error Off = No protection
5	FBDIMM LEDs* (memory board 1)	Amber = Failure Off = Normal
6	FBDIMM LEDs* (memory board 2)	Amber = Failure Off = Normal
7	Processor 1 LED	Amber = Failure Off = Normal
8	PPM 1 LED	Amber = Failure Off = Normal
9	Processor 2 LED	Amber = Failure Off = Normal
10	PPM 2 LED	Amber = Failure Off = Normal
11	Hot-plug fan LEDs	Amber = Failure or fan is not installed Off = Normal
12	Internal system health LED	Green = Normal (system on) Amber = System health is degraded Red = System health is critical Off = Normal (system off)
13	External system health LED (power supply)	Green = Normal (system on) Amber = Redundant power supply failure Red = Power supply failure. No operational power supplies. Off = Normal (system off)
14	Overtemperature LED	Red = Overheating, critical Off = Normal
15	System power LED	Green = System has AC power and is powered on Amber = System has AC power and is in standby mode Off = System has no AC power

* If all FBDIMM LEDs for a memory board are flashing, the memory board is unseated.

 

nah untuk menangani nya , dari beberapa saran di forum HP ,

langkah pertama cabut  baterai dari system board , langkah ke dua cabut memori board kemudian masukan lagi, langkah ke tiga masukan lagi baterai ke system board(mother board)  terakhir  coba boot lagi ,

dari saran di atas jika masih belum bisa boot dan led Internal system health masi menyala merah , di langkah ke dua setelah cabut memori board , cabut juga satu persatu memori nya kemudian pasang lagi dan coba boot ulang.

semoga bermanfaat  :)
