RS-232 UPS Port Does Not Respond

The following are possible causes for the RS-232 port not responding on an MPE/iX or
HP-UX system:
• The version of the operating system is required to support UPS is not valid: HP-UX 9.04
(or later) or MPE/iX 5.0 (or later).
• The port is not configured correctly on the computer. It must be configured as a valid
serial port. Refer to these sections of this manual: "Connecting the Communications
Link" in Chapter 3, "Configuring HP-UX for the PowerTrust UPS" in Appendix C, and
"Configuring MPE/iX for the PowerTrust UPS" in Appendix C.
• The UPS port may not be in computer mode. This may require a patch in 9.04
(PHC0_3692).
• Although it appears to be a standard RS-232 cable, the wrong cable may be connecting
the UPS to the computer. It requires one of these special RS-232 cables:
5061-2575 DB9 9-pin male/DB9 9-pin female (2.5 meter)
5061-2569 DB9 9-pin male/DB25 25-pin male (2.5 meter)
5063-5352 DB9 9-pin male/DB25 25-pin male (4 meter)
