是否可以停機那麼久來作維護
由於不想停機影響公司作業
所以已經習慣性的多買一些當備品
server容易掛的東西一定要成雙(HD,POWER,網卡)
一塊4mx 停電以後就找不到了 本人測試電池電壓4.88 另一塊2008年12月29號関機 2009年1月3號開機就報pci錯誤 4mx就抓不到了 我把4mx的電池拔掉就能認到 找了另一個x360機器上4mx 電池換過來也能認到 抓不到的4mx卡在x345的服務器上能認到 我暈死了 難道必須換電池還是我的卡的故障和你的不一樣 期待回復 mail:rtm009@gmail.com 本人在北京
本人看有關4mx電池的文章說x360 x365的機器會自動屏蔽故障卡 本人e文不好 不知道到底怎麽囘事兒
ServeRAID battery failures and their effect on host systems - Servers
RETAIN tip: H18443
Additional information
There are different ways in which systems behave when the battery is approaching its end of usable life. In
many cases, the battery no longer charges to its specified voltage as it reaches the end of its usable life.
This is detected by the ServeRAID controller and an alert is generated by the ServeRAID Manager to
indicate that the FRU battery needs to be replaced.
In other cases, as the battery fails, the charging circuit on the ServeRAID controller draws a short current
surge from the PCI/PCI-X Slot. The PCI/PCI-X current-limiting circuit on some servers, like the xSeries 360
and xSeries365, turns off power to the PCI Slot and the controller is no longer seen at POST.
This behavior can be confirmed by watching the controller in the Slot at power on. The Slot powers up,
indicated by the green power LED, then shortly after, powers off with the amber warning LED lit. On
systems without PCI-X "current limiting" circuitry, the controller may return a "controller failure" or "battery
failure" message during POST, depending on the status of the battery.

NVRAM Supervisor = Non-Volatile RAM 控制器
一般的 RAM 如果移除電源, 內容就會消失.
NVRAM 是指電源移除後, 這種 RAM 內部的資料仍會留存.(所以稱 "NV")
單顆的 NVRAM 是內部有 RAM 和 EEPROM.
當電源失效時, 會送出一個信號給 NVRAM, 它自己趕緊把內部的 RAM 內容寫到 EEPROM 內.
下次電源來了後, 再把 EEPROM 的內容填回 RAM 去. 宛如 RAM 內容未消失般.
(一般是 SAVE 和 RESTORE 兩個信號)
但 NVRAM 比較貴或容量不大, 所以 這顆 IC + 黃色電池 + RAM(需 CMOS 製程, 取其耗電小)
搭配起來就等同 NVRAM 了.

查了一下, 內部結構是:
很簡單, 就是一個鋰電池而已. 看規格是 2.8V, 120mAh.
如果壞了或沒電而且買不到, 換上一個 CR2025 (3V, 165mAh. 工程計算機常用) 的電池就可以.
