硬件設置
硬件設置作為IS420UCSBH4A訂購信息的一部分，IS420UCBSH4A在出廠時由用戶指定的選項填充。CPU速度、RAM大小和閃存大小不可由用戶升級。要更改CPU速度或RAM/Flash大小，請聯系客戶服務以獲得退貨授權（RMA）。VMIC客戶服務電話：1-800-240-7782。或發送電子郵件至customer.service@vmic.comIS420UCSBH4A經過系統運行測試，并隨工廠安裝的收割臺跳線一起出廠。單板CPU跳線和連接器的物理位置如第27頁的圖1-1所示。CPU板跳線和接頭的定義包括在表1-1至表1-7中。注意：用戶可以更改或修改下表中標記為“用戶可配置”的所有跳線。用戶不應修改所有標有出廠配置的跳線。
使用方法
IS420UCSBH4A符合單插槽6U雙歐卡（雙高度）的VMEbus物理規范。它可以直接插入接受這種類型板的任何標準機箱。警告：通電時請勿安裝或卸下電路板。以下步驟描述了VMIC建議的IS420UCSBH4A安裝和通電方法：1.確保設備電源已關閉。2.選擇機箱插槽。IS420UCSBH4A必須連接到雙P1/P2 VME總線背板。如果IS420UCSBH4A是VME總線系統控制器，請選擇第一個VME總線插槽。如果不同的板是VME總線系統控制器，請選擇除插槽1之外的任何插槽。IS420UCSBH4A不需要跳線來啟用/禁用系統控制器功能。注：散熱器輸出側測得的空氣流量要求大于350LFM。
hardware setup
The hardware settings are part of the IS420UCSBH4A ordering information and are populated by user specified options at the factory. CPU speed, RAM size and flash memory size cannot be upgraded by users. To change the CPU speed or RAM/Flash size, contact customer service for a Return Authorization (RMA). VMIC customer service telephone: 1-800-240-7782. Or send an email to customer.service@vmic.comIS420UCSBH4A The system is run tested and shipped with the factory installed header jumper. The physical location of the board CPU jumper and connector is shown in Figure 1-1 on page 27. The definition of CPU board jumper and connector is included in Table 1-1 to Table 1-7. Note: Users can change or modify all jumpers marked as "User Configurable" in the following table. Users should not modify all jumpers marked with factory configuration
usage method
IS420UCSBH4A conforms to VMEbus physical specification of single slot 6U dual card (dual height). It can be directly inserted into any standard chassis that accepts this type of board. Warning: Do not install or remove the circuit board when it is powered on. The following steps describe the VMIC recommended installation and power on method of IS420UCSBH4A: 1. Make sure that the equipment power is turned off. 2. Select the chassis slot. IS420UCSBH4A must be connected to the dual P1/P2 VME bus backplane. If IS420UCSBH4A is a VME bus system controller, select the first VME bus slot. If the different board is a VME bus system controller, select any slot except slot 1. IS420UCSBH4A does not require jumpers to enable/disable system controller functions. Note: The air flow measured at the radiator output side is required to be greater than 350LFM.
