Redundant Power Upgrade 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.
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. power controller board...
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 E CD-ROM supplied with the XPRESS UILDER server, or see the "Disassembly and Reassembly"...
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.

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.
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.

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. 10 Redundant Power Upgrade Kit 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).
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.
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.
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.
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.
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.
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.
