Remote Support Modem Configuration - HP 3000 Series Handbook

For HP Internal Use Only
13. When all memory SIMMs are installed on the CPU card, replace the CPU card into the
computer.
14. Replace the cover plate.
15. Re-attach the power cord that was removed.
16. Turn ON the computer. When the computer completes self-test, the amount of configured
and tested memory is displayed, note the displayed number and verify that all installed
memory is recognized.
The computer system is now ready to complete the boot process. The new memory is
automatically configured into the computer during the power up and self-test process.
Caution
I
During power on CPU selftest, PDC checks the memory configuration. If PDC
finds an invalid memory configuration it will issue a selftest halt code (hex
707C) and stop the boot process.
Remote Support Modem Configuration
This section contains information for connecting specific modems to the HP 3000 Series 9x8
Family and HP 9000 800 Ex5 Class system Multifunction I/0 (MFIO) modem interface
connectors. This section also discusses the signal line behavior of the Multifunction I/0
modem interface to aid in configuring modems that are not listed.
General rules for configuring modems:
• The modem must be set up to respond to DTR.
• CTS should follow RTS.
• DSR must follow OH, not DCD.
• For Bell mode, the modem should disregard RTS.
• Both modems should either be set to the same compression mode or both should be set to
no data compression. If you have problems connecting two modems, usually the fault is that
one is enabled for some MNP level and the other modem is set for no data compression.
If the modem sends up-modem dialog with all of the signals asserted, it is possible that the
user will be logged off immediately when a password is enabled for the Access Port (AP). Fix
this by setting the modem so it does not report connection status via the data path.
Note
V.22bis/V.25bis modes are not supported on the HP 9000 8x7 Multi-function
I/0 interfaces.
The supported modems are described below.
