ERIFICATION
10.3.1
Frame Control Verification Overview
Frame control verification is required to verify Cheetah chassis component operations and isolate
abnormalities prior to connecting peripheral equipment to the system. To assist the user, this
verification sequence uses a graphic user interface (GUI) that is communicating directly with the
chassis Matrix Frame Controller (MFC) for the diagnostic portion of the sequence. The following
equipment/documentation is required:
•
PC with preloaded PESA Switching Systems, Inc. ViewPort software.
•
Null-modem serial cable (length determined by distance the PC will be from the chassis)
•
ViewPort Manual (P/N 81-9059-0558-0)
•
Customer’s Cheetah chassis packing list or specification sheet.
10.3.2
Frame Strobe Setting Verification
While referring to the appropriate Chapter for the frame that is being verified, document and archive
the frame’s present strobe settings as follows:
1)
Access the MFC compartment. If necessary, remove the top-most MFC module and blank
cover to expose the strobe switches for viewing.
2)
Document each strobe switch setting and archive. (Archiving should include an electronic file
and hard-copy for ease of future retrieval. This information is invaluable when communicating
with the PESA Customer Service group.)
3)
Re-install the components that were removed in Step 1.
10.3.3
Frame Control Verification Procedure
Perform the following sequence:
1)
Perform the chassis pre-start verification checks and startup sequences as outlined in Sections
10.1 and 10.2 in this Chapter.
2)
With the chassis energized (ON) and while referring to the ViewPort manual, carefully connect
the null-modem serial cable to the MFC, DB-9 serial connection port and the PC’s serial port.
If there are any errors noticed while performing the sequential steps in the
Frame Verification Procedure, perform troubleshooting sequences to
correct the problem(s) prior to proceeding to the next step.
3)
At the PC, access the ViewPort software program and establish communication with the MFC
(the module’s
RX
and
TX
LEDs will be flashing green and yellow, respectfully).
