HP Integrity rx8640 Server E-Link Cable Installation
NOTE: This section describes the installation of the E-link cables between the SEU and the
server.
INSTALLATION NOTES BEFORE GETTING STARTED
• Before attaching the SEU, the server must be shut down. Schedule this with the customer
prior to beginning the SEU installation.
• The SEU is only supported with servers containing a minimum of three cell boards. The cell
boards must be loaded in the server in cell board slots 0, 1, and 2. Cell board slot 0 is the
top-most slot in the server chassis.
• The SEU ships with both core I/O cards installed.
• If the server only has one core I/O card installed, another core I/O card must be installed in
the server to support the SEU.
• When the SEU is installed in the same rack cabinet as the server, the SEU must be mounted
directly above the server. This could require moving existing products to another rack
cabinet.
• When the SEU is installed in an adjacent rack to the server, adhere to the following guidelines
for installation:
— Two SEUs can be installed in a single rack with proper anti-tip feet, system interlock
rod, and ballast.
— The two racks must be secured together with rack tie kits and the rear doors must be
removed. The racks must be either 41U or 33U. A 25U rack is not permitted for SEU
installation.
— The top of the SEU must be at the same level as the top of the host server to enable a
complete service loop accomplished by routing the cable out the back of one rack into
the back of the other rack so both the host server and the SEU can be fully extended in
the locked position simultaneously.
— The space above and below the SEUs may be used, but care must be taken so equipment
installed in this space does not interfere with the interlock mechanism or SBA cable
routing.
• The server operating system will need to be updated.
Shutting Down nPartitions
This section describes how to properly shut down an nPartition.
For complete details on system administration for nPartitions, refer to the HP System Partitions
Guide.
Shutting Down an nPartition
This procedure is for checking the boot status of an nPartition and, if needed, shutting down
HP-UX on the nPartition.
1. Advise the customer that the system (one or more nPartitions) must be shut down for repairs.
Ensure that the customer has a current backup, and inform the customer of the anticipated
downtime.
2. Login to the server MP.
3. Use the Virtual Front Panel (VFP) to view the current state of the nPartition that you will
shut down.
From the MP Main menu, enter VFP to access the Virtual Front Panel menu, and select the
nPartition whose boot state you want to view.
