Redundant Power Upgrade Kit Installation Procedures This guide contains the information necessary to install, test, and troubleshoot (if necessary) the Redundant Power Upgrade. This guide is written for knowledgeable users, trained customer engineers, system analysts, service center personnel, and dealers. With the upgrade kit installed, the server will have power system redundancy that allows the system to operate with a single power supply failure.
NEC
The NEC Redundant Power Upgrade Kit contains the components necessary for adding system power redundancy capabilities to the NEC Express5800/120Mc2 and Express5800/120Mc3 Server Systems. The following items shown in the figure below are included in the kit.
Use the following installation information as a guide for installing the upgrade kit. Also, see the option installation instructions, which are located in the "Upgrading Your System" Chapter of the User's Guide that come with the online documentation on the NEC EXPRESSBUILDER CD-ROM supplied with the server, or see the "Disassembly and Reassembly" Chapter of the Service Guide.
Removing the Server Side Panels To install the redundant power upgrade in the server, the server side panels must be removed. Also, please note that the right side panel removes in the same manner as the left side panel. ! CAUTION For proper cooling and airflow, do not operate the system with the side panels removed. Always replace the panels before powering on the system. ! WARNING Before removing the server covers, turn off the power and unplug the system power cables.
Removing a Server Side Panel 6 Redundant Power Upgrade Kit Installation Procedures
Removing the Standard Power Supply and Rear Mounting Plate 1. Power off the system and unplug the power supply ac power cable. 2. Remove the right side panel as described earlier. 3. Disconnect the internal power cables from the power supply inside the chassis. 4. Remove the two screws securing the front of the power supply to the power supply retaining bracket that is attached to the inside of the chassis. 5.
Removing the Power Supply Retaining Bracket 1. Power off the system and unplug the power supply ac power cable. 2. Remove the right side panel and standard power supply (if not already removed) as described earlier. 3. Remove the screw (see figure below) that secures the power supply retaining bracket to the chassis. 4. Remove the power supply retaining bracket from the chassis. Note: The power supply retaining bracket is no longer needed.

Installing the Upgrade Components Install the following upgrade components: ! power controller board ! two jumpers ! LED/switch assembly ! interlock switches ! two redundant power supplies. See the following paragraphs for installation procedures.
Installing the Power Controller Board ! CAUTION Electrostatic Discharge (ESD) can damage electronic components. Install the new power controller board in the server as follows. 1. Align the power controller board (A) so that its side power supply connectors (J1, J3, J5, and J8) face the power supply slots (see the figure below). 2. Install and secure the power controller board to the chassis with the ten screws (B) and two tie wrap clamps (C) supplied with the kit.
3. Attach the main power cable (A) that comes from the system board power connector (see list below) to J9 on the power controller board (see the figure below). Secure the cable by threading a tie wrap (B) through tie wrap clamp (C) and around the cable, and tighten. Trim the plastic tie wrap. For 120Mc2 System Board use the power cable from power connector P23. For 120Mc3 System Board use the power cable from power connector P28. 4.
Installing Jumpers and Disconnecting the Intrusion Switches To disconnect the intrusion switches and install the two new jumpers perform the following procedures. 1. Remove the cable from connector J5 on the SCSI backplane (see the following figure). The cable will be reconnected when installing the Interlock Switches later in this Guide. Unplugging the Intrusion Switches on the SCSI Backplane 2.
Installing the LED/Switch Assembly Install the new LED and presence switch assembly in the server as follows. 1. Insert the top and bottom power supply LED/switch assembly modules as shown in the following figure. In the following two figures match A to A and B to B. Installing the Top and Bottom LED/Switch Assembly Modules 2. Cable the top and bottom power supply LED/switch assembly modules exactly as stated below and as shown in the following figure.
Note: When plugging in the Data cable connector (D) and the Top and Bottom LED cable connectors (C and E), pin 1 on these connectors must be positioned to line up with pin 1 on the corresponding connectors they are plugging into. For the location of pin 1 on these connectors, see the following figure. A Bottom power supply LED/switch assembly module. B Top power supply LED/switch assembly module. C Top PSU LED cable connector. D Data cable connector. E Bottom PSU LED cable connector.
Installing Interlock Switches To install interlock switches attach the cable connector previously removed from J5 on the SCSI backplane to J13 on the power controller board (see the following figure). Also, see step 1 in paragraph "Unplugging the Intrusion Switches and Installing Jumpers" for cable connector previously removed from J5 on the SCSI backplane.
Installing the Redundant Power Supplies Install the two redundant power supplies in the server as follows: Perform the following procedures for each power supply. 1. Attach the two power supply cables to the connector bracket on the back of the power supply carrier supplied with your kit (see the following figure). Attaching the Two Power Supply Cables 2.
4. Ensure that both power supplies have their line voltage selector switch set to the same voltage (see the following figure). ! CAUTION Before you plug the system power cord into an AC outlet, ensure the input line voltage setting for the power supply is correct. To use the system with line source voltages between 200 and 240 VAC, the line voltage selector switch on the power supply must be set to 230.
Installing the Server Side Panels Use this procedure to install the two side panels on your server. (See "Removing the Server Side Panels" earlier in this document for additional information.) Install the side panels as follows. 1. From the rear of the server align the locking tabs on each side panel with the corresponding slots in the chassis. 2. Slide each side panel towards the front of the chassis until it locks in place. 3. Secure each side panel with its thumbscrews.
Power up and test the server as follows. 1. Press the Power button on the front panel. 2. The server boots up. 3. Check the front system indicators for power alarms and abnormal power status. 4. If no messages appear on the monitor screen, turn off the server and see "Troubleshooting,"next. Troubleshooting After installation of the upgrade kit, during the server's initial power up sequence, if no messages appear on the monitor screen, check the following.
