I recently got a 4501 as part of a bunch of stuff a friend-of-a-friend was giving away rather than moving. Today I tried to fire it up.
Its console is a DE9, and, basd on what I've been able to find, it's supposed to use the same pinout as peecee DE9 serial ports. But it doesn't seem to; when I use a voltmeter (a fairly high-impedance one - a Fluke 87) to measure the voltage on pin 3 relative to pin 5, I get a voltage in the low tens of millivolts. It's not just dead power; when I plug power in, the "Power" and "Error" lights light, with the "Error" light going out after about seven seconds, and I plugged one of the Ethernets into a switch and got link. It's also not just a dead voltmeter; the same voltmeter, making the same measurement on a serial port on another machine, works fine, showing between 8 and 9 volts. I tried other pins and wasn't able to find any pair of pins showing more than .03V or so. I opened the case, in case it was a disconnected cable or some such, but the console port connector is soldered directly onto the board. I don't see any obvious damage, but I don't really know the 4501. Does this mean I've just got a fried unit? Or is there something else that could be wrong here? /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML [email protected] / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
