The mon-cxma program provides the following capabilities:
Use the following procedure to execute the mon-cxma program from SMIT.
Vital Product Data (VPD) is a collection of device information such as part numbers, serial numbers, and engineering change levels. This information is used by service personnel to determine compatibility of hardware components. The data is collected from the 128-port asynchronous subsystem and automatically added to the system configuration. Service representatives may find it necessary to view this information before making upgrade or replacement decisions concerning the 128-port subsystem.
The following figure illustrates the main panel for the monitor program.
On this screen, RANs are represented by [AC] if active, or (-) if inactive (turned off, defective). In this example, Adapter Line 1 has four directly attached RANs which are daisy-chained directly off the 128-port adapter. They are all active and assigned node numbers sequentially from 01 to 04 .Adapter Line 2 has two RANs attached. The first RAN, node 01 , is directly attached to the 128-port adapter while the second, node 03 , is connected to the first using EIA 232 modems.
You can move between the Adapter Lines or RANs by using the up and down arrow keys. If you press Enter on an Adapter Line, the ADAPTER CONFIGURATION screen for that adapter is displayed.
The ADAPTER CONFIGURATION screen shows the adapter's line configuration as well as the configuration string stored in memory during system startup. This string is used during initialization to determine line speeds and connection types between the 128-port adapter and RAN. It is useful for diagnosing configuration problems.
This screen is updated at half second intervals and shows the current status of the selected port.
The box in the center of the screen shows the state of the EIA 232 signals TD, RD, CTS, DSR, CD, DTR, and RI, plus input and output flow control status (IFC and OFC) for the selected port.
An inactive signal is indicated by a dash (-) under its name. An active signal is indicated by a block under its name. If data is currently being transmitted or received for the selected port, a blinking "X" will appear under the signal name (TD or RD, respectively).
The status of the RAN is represented at the right-hand end of the box with [AC] if the connection to the host adapter is good.
Beneath the line status box are the input, output and control modes for that port. These are terminal attributes with descriptions.
Loop Back Test Passed.
