No. In example if you use a HP/Cisco DB-9 for a APC the UPS will restart direct. (as it will receive a signal on a pin reserved for a command) For other product most use the standard pinout, but be advised to watch yourselft on critical gear as it can produce un-wanted result.


It depends. You'll likely be able to use it on HP and Cisco gear, but there are some situations where the pinout is different or maybe you'll have a device with a DB-9->DB-9 requirement. If in doubt, use the manufacturer's cable.
