Hardware Installation
3.5.1.
PSA-3000 / PVA-3000 / PSL-3000 Test Blade Installation
The chassis slots for the PSA-3x02, PVA-3102, and PSL-3x02 blades are numbered from 1-12 (left to right) in the
frame. Blades should generally be installed from left to right, however this is
not
a strict requirement for proper
operation of the instrument under software control. In PSA software, test ports are addressed generally by Slot
number and Port number.
Note: Test blade installation is not applicable to the PSA-3402, PSA-3002, PVA-3002, PSL-3x24, and PSA-3x48.
These models are fully populated with test blades as furnished.
3.5.2.
Rack Mounting Considerations
Chassis-based configurations may be operated stand-alone or mounted inside a 19-inch rack.
The top and bottom air vents and back-panel fans on the chassis provide required cooling for the test cards. Cooling
is especially important for PowerSync test blades as those have the capability to generate up to 100 watts of heat per
test blade. When rack mounting the chassis, a 1U (1.7”) spacing
must
be maintained above and below the
instrument, without front-side obstructions.
NOTE!
OBSTRUCTION OF THE TOP OR BOTTOM VENTS OR THE FANS COULD DAMAGE THE
HARDWARE UNDER HEAVY CURRENT PoE LOADS, AND WILL VOID THE WARRANTY.
3.5.3.
Powering Up PSA-3000, PVA-3000, and PSA-3402 Instruments
Connect the supplied AC cord to the back of the chassis, and then to a
properly grounded
AC outlet (see “Safety
Precautions”). Turn on the power switch on the back of the chassis. The test ports should all flash their LED’s for
about 2 seconds, and the PSA controller should then flash its LED indicators briefly. At this point, the instrument is
available for all testing operations.
NOTE!
The ground connection between the instrument and the AC outlet should never be removed or bypassed.
3.5.4.
Powering Up PSA-3002 and PVA-3002 Instruments
Connect the supplied modular power supply to the 5VDC input in the rear of the instrument and then to a properly
grounded AC outlet (see “Safety Precautions”). If provided, press the momentary power switch in the back of the
chassis. The test ports should all flash their LED’s for about 2 seconds, and the PSA controller should then flash its
LED indicators briefly. At this point, the instrument is available for all testing operations.
NOTE!
Use of a modular power supply other than the AC adapter furnished by Sifos is not recommended and may
have adverse consequences to either the test instrument and/or to measurement and testing results. Under no
circumstances should the GROUND connection on the modular power supply be removed or bypassed.
3.5.5.
IP Address Set-Up via Console Port
The instrument is typically shipped from the factory with an IP Address of
192.168.221.105
. (
PSA-3x48’s are
configured with addresses
192.168.221.105
and
192.168.221.106
.) Under typical situations, the user will probably
need to change this to an address that matches their local network settings.
Users may work with the
Console
port to re-configure IP address and IP mask bits. Newer
Console
ports are USB
while older
Console
ports are RS-232 DB9 connections on the PSA/PSL-3000 slot 0 controller blade. In either case,
the communication protocol is RS-232 and the
Console
port is treated as a Serial (“COM”) port in the host PC.
Terminal emulation software (e.g. HyperTerminal) may then be used to communicate from the host computer.
NOTE!
The PowerSync instrument’s console port is available exclusively for IP Address set-up and PSA Controller
firmware updates. Under normal use it should be left disconnected. IP address configuration and PSA Controller
firmware may also be performed from PowerShell PSA software without using the Console Port.
USB Console Connections
– PSA-3000 and PSA-3402
If the PSA-3000 controller includes a USB (type B) jack, then a USB connection should be made to the host
computer. Generally, both the host computer and the PSA/PSL instrument should be turned on before completing
the USB connection. Communication over USB to the Console port will require that host PC have driver software
required to recognize the
FTDI
RS-232 Serial to USB converter and then map that interface to a virtual COM port.
The required driver software depends on the instrument:
PSA/PSL/PVA-3000 Chassis:
ftdibus.inf
and associated files for 32-bit and 64-bit computers
PSA-3402:
psa3000port.inf
and associated files for 32-bit and 64-bit computers
