Expansion Tower
Note
Before You Begin
CAUTION!
CAUTION! The SCSI
bus may be damaged if
you connect or
disconnect any units
when the power is on.
This expansion tower provides the additional bays for expanding
beyond the drives in the server tower. It includes a SCSI cable to
connect the two towers and an external active HP SCSI terminator
to be installed on a rear SCSI connector. SCSI IDs are set
automatically on HP CD-ROM drives based on their position in the
tower. The topmost position on this accessory tower is ID 0 on the
second SCSI bus "B", and the lowest position is ID 6 on the second
SCSI bus "B". All 14 drives are read by the server module located in
the server tower.
Consult the User's Guide accompanying the expansion tower for its
specific installation instructions. Complete the SCSI cable
connection to the server tower, the SCSI termination connection,
and the power cord connection as directed in that guide. The "Steps
to Connect the Towers" (below) include the steps needed to start up
both towers.
To install the expansion tower after the server tower has been
installed, you must switch off power to the server tower before
installing the expansion tower. After installing the expansion
tower, follow the "Steps to Connect the Towers" to restart the
server tower.

Steps to Connect the Towers

•
Verify with your network administrator that a 10Base-T
(Ethernet) or 100Base-TX (Fast Ethernet) network connection
is ready for the server tower. Locate the twisted-pair network
cable (with an RJ-45 connector).
•
Verify that the tower's power is off.
•
Verify that the power supply input voltage is set according to
the power standards in the country of use; set the voltage
switch on the rear of the tower (see the illustration on the next
page) to 115 volts or 230 volts. Also verify that the power cord is
appropriate for the country of use (see page 2-2).
•
If you are expanding the server tower (using its rear SCSI
connector illustrated below), you must complete all cable and
termination connections on both towers before you apply power.
Apply power to the expansion tower before you apply power to
the server tower. See also page 2-3.
