10 Introduction
Table 1-3: Rear Panel Legend
C Remote Monitoring
Connector The D-sub9 connector acts as a remote
monitoring connector, when connected to a
remote computer
using a standard D-sub9 cable, with pin
assignments shown in Figure 1-7
Note: The remote monitor port is Rx-Tx/Tx-Rx
crossed, such that a RS-232 cable with Rx-Rx/
Tx-Tx connection must be used
D Inhibit/Voltage
Monitoring DB-9
Connector The DB-9 connector monitors the four main
voltage rails via digital multimeter
X voltage rail pin assignments
shown in Figure 1-7
X 10 kΩ current limiting resistors on
each voltage rail prevent acciden-
tal overload
X one Inhibit (active low) pin is pro-
vided to power the chassis on/off
when the Inhibit Switch is in the
MAN (manual) position, such that
chassis is powered on when
Inhibit pin is logic high or open,
and off when Inhibit pin is
grounded
E Inhibit Switch In the DEF (default) position, the front panel
power button turns the power supply on/off, and
in the MAN (manual) position, the INHIBIT pin
on the DB-9 connector turns the power supply
on/off
F Fan Switch In the HIGH position, fans operate at maximum
speed, and in AUTO, the fans run based on the
monitored chassis temperature
G Universal Power Inlet Accepts C19 power outlet-equipped connection
H Chassis Ground Lug The ground wire can be crimped to the ground
lug, using a crimp tool of the appropriate size,
with the other end connected to ground
