    頂部護罩拆卸

    從3301機架上拆下RIM。從RIM上拆下頂部護罩。從RIM PWA上卸下原始固件IC。將升級固件IC安裝到RIM PWA上的插槽中。更換RIM頂部護罩。將RIM更換到3301系統(tǒng)中。使用3301機架配置軟件重新配置RIM。以下頁面提供了上面列出的一些步驟的詳細說明。請在繼續(xù)操作前進行全面檢查。頂部護罩拆卸1)頂部護罩。2) 對峙。3) 螺絲刀。步驟1.將大平頭螺絲刀放在頂部護罩下方和后支架的脊上,并向上提起螺絲刀,將蓋子從后支架上松開。步驟2.上下移動頂部護罩,使其從兩個前支架上松開。3301/40操作和維護5維護35原始固件IC拆卸步驟1.將小平頭螺絲刀插入IC兩端的唇部下方。該圖顯示了要移除的芯片的大致位置,但不一定是其方向。步驟2.用螺絲刀輕輕撬起芯片的一端。移動到芯片的另一端并重復(fù)。繼續(xù)此過程,直到芯片從插座上松開。5維護3301/40操作和維護36升級固件IC安裝將升級固件IC裝入PWA。確保IC的缺口端與插座的缺口端匹配。確保IC牢固地安裝在插座中。頂部護罩的更換更換頂部護罩。確保頂部護罩上的槽口位于模塊的左上角,如“頂部護罩拆卸”下的圖所示。

    將頂部護罩上的孔與支架對齊

    并在每個支架周圍向下按壓,直到它們卡入到位。5.3實時時鐘更換小心正確處理實時時鐘組件。不要焚燒!機架接口模塊上的實時時鐘組件使用內(nèi)部鋰電池,需要每3至10年更換一次。更換間隔取決于環(huán)境條件,如工作溫度。3301/40操作和維護5維護37放電的鋰電池可能會在機架斷電時導(dǎo)致操作信息丟失。實時時鐘組件采用插孔設(shè)計,便于更換。有關(guān)必須更換實時時鐘時顯示的消息,請參閱第6節(jié)中的系統(tǒng)事件列表消息。請聯(lián)系最近的本特利內(nèi)華達公司辦公室進行更換。為了替換實時時鐘,遵循第5.2節(jié)(執(zhí)行固件升級)中的說明,但以下情況除外:時鐘組件在Pwa上的大致位置如下所示:組件和插座排列如下:6故障排除3301/20操作和維護38 6故障排除本節(jié)描述了如何排除機架接口模塊或I/O的故障通過使用驗證屏幕、LED、系統(tǒng)事件列表和報警事件列表提供的信息。您可以使用機架配置軟件顯示驗證屏幕和兩個事件列表。6.1驗證執(zhí)行機架接口模塊的驗證:1.將運行機架配置軟件的計算機連接到3301機架(如果需要)。2.從機架配置軟件的主屏幕選擇實用程序。3.從實用程序菜單中選擇驗證。4.選擇機架接口模塊并選擇要驗證的通道。5.按下驗證按鈕。6.選擇前端口或后端口以獲取狀態(tài)。7.模塊OK(正常)狀態(tài)將顯示機架接口模塊的狀態(tài),通道OK(正常狀態(tài))將顯示通道的狀態(tài)。

    Top shield removal

    Remove the RIM from the 3301 rack. Remove the top shield from the RIM. Remove the original firmware IC from the RIM PWA. Install the upgrade firmware IC into the slot on the RIM PWA. Replace the RIM top shield. Replace the RIM into the 3301 system. Use the 3301 Rack Configuration Software to reconfigure the RIM. The following pages provide detailed instructions for some of the steps listed above. Please check thoroughly before continuing. Top shield removal 1) Top shield. 2) Confrontation. 3) Screwdriver. Step 1. Place a large flat head screwdriver under the top shield and on the ridge of the rear support, and lift the screwdriver upwards to release the cover from the rear support. Step 2. Move the top shield up and down to release it from the two front supports. 3301/40 Operation and Maintenance 5 Maintenance 35 Original Firmware IC Removal Step 1. Insert a small flat screwdriver under the lip on both ends of the IC. The figure shows the approximate location of the chip to be removed, but not necessarily its direction. Step 2. Gently pry up one end of the chip with a screwdriver. Move to the other end of the chip and repeat. Continue this process until the chip is released from the socket. 5 Maintenance 3301/40 Operation and Maintenance 36 Upgrade Firmware IC Installation Install the upgrade firmware IC into the PWA. Make sure that the notched end of the IC matches the notched end of the socket. Ensure that the IC is securely installed in the socket. Top Shield Replacement Top Shield. Make sure that the notch on the top shield is located in the upper left corner of the module, as shown in the figure under "Top shield removal".

    Align the holes in the top shield with the brackets

    Press down around each bracket until they click into place. 5.3 Replace the real-time clock. Carefully and correctly handle the real-time clock components. Don't burn! The real-time clock component on the Rack Interface Module uses an internal lithium battery and needs to be replaced every 3 to 10 years. The replacement interval depends on environmental conditions, such as operating temperature. 3301/40 Operation and Maintenance 5 Maintenance 37 A discharged lithium battery may cause loss of operational information when the rack is powered down. The real-time clock component adopts the jack design for easy replacement. For messages that appear when the real-time clock must be replaced, see System Event List Messages in Section 6. Please contact the nearest Bentley Nevada office for replacement. To replace the real-time clock, follow the instructions in Section 5.2 (Performing Firmware Upgrades), except for the following: The approximate location of the clock components on the Pwa is as follows: Components and sockets are arranged as follows: 6 Troubleshooting 3301/20 Operation and Maintenance 38 6 Troubleshooting This section describes how to troubleshoot a rack interface module or I/O fault by using the verification screen, LEDs, system event list, and alarm event list. You can use the Rack Configuration Software to display the verification screen and two event lists. 6.1 Verification Perform the verification of the Rack Interface Module: 1. Connect the computer running the Rack Configuration Software to the 3301 rack (if required). 2. Select Utilities from the main screen of the Rack Configuration Software. 3. Select Verify from the Utilities menu. 4. Select the Rack Interface Module and select the channel to verify. 5. Press the Verify button. 6. Select the front port or the rear port to get the status. 7. Module OK Status will display the status of the Rack Interface Module and Channel OK will display the status of the channel.
