System Installation
PART TWO
HP 32435A SERIES III COMPUTER SYSTEM INSTALLATION
WARNING
Prior to performing any installation procedures,
ensure that the three Power Control Module cir-
cuit breakers (located at bottom rear of the CPU
Bay) are set to their OFF positions and that the
main power cable is not connected to the power
source. Failure to comply may result in serious
injury or death and severe damage to equipment.
11-11. EQUIPMENT BAY INSTALLATION
The system equipment bay(s) are completely assembled and tested
at the factory prior to shipment. If the system to be installed
is a 2-bay model (Option 200), the two equipment bays must first
be mechanically and electrically connected in accordance with the
instructions contained in the HP 3000 Computer System Installa-
tion Manual, part no. 30000-90147. Once this is accomplished or
if the system to be installed is a I-bay model, simply position
the bay(s) as desired, extend and lock the anti-tip base exten-
sion legs in place, and lower the equipment bay feet located at
the end of the extension legs and at the rear of the bay(s).
11-12. Isolation Transformer Strapping
The computer system is shipped from the factory with its isola-
tion transformer pre-strapped for 208 VAC to GO-Hz sites and for
230 VAC to 50-Hz sites. However, to ensure proper system opera-
tion, check and, if necessary, restrap the isolation transformer
as follows:
a. Using a voltmeter, measure the actual steady-state voltage at
the AC receptacle that has been installed to provide power to
the computer system.
b. Refer to table 11-5 and check that the measured steady-state
voltage is within the limits specified for the rated voltage
the customer contracted for during his computer site prepara-
tion. If the voltage is within the limits specified in table
11-5, proceed to step c. If the voltage is not within the
limits specified for the contracted rated voltage, the com-
puter site has not been properly prepared. Do not proceed
with the system installation until the site has been properly
wired in accordance with the inst,r uctions conta ined in the HP
3000 Computer System Site Preparation Manual, part no. 30000-
90145.
c. As viewed from the front, remove the CPU equipment bay right-
side panel.
