Re: Question on Perle 494 Control Unit/Communications... -- MIDRANGE-L

Chuck,

I haven't worked with Perle units in a while, well at least not since Wednesday!

The Perle itself will continue to communicate with the AS/400 as long as it can reach it. Even if no devices are on line it will maintain the APPC link (likely via ANYNET in your case) and the workstation controller should stay active. It's likely that once the power came back on the Perle rebooted and came alive, or possibly an infrastructure device (aka switch or hub) was NOT up (maybe plugged into the wall?) and the link was broken. Hubs/switches come up real fast so that could explain the quick return on power restoration.

Hi Folks,

We had our largest distribution center down this morning for about 30
minutes - no power.

We use a frame relay network. Adtran DSU/CSU, Cisco Router, Perle Control
Unit w/Ethernet card, Netgear Switch and APC rack mount UPS.

While they were without power I could ping the Cisco Router, telnet into it,
etc. but I could not successfully ping the Perle Control unit. Get the
Controller Failed messages on QSYSOPR, etc.

So not being a communications guru by any stretch, but does the Perle "poll"
for responding devices to keep it's connection alive or something ? Reason I
ask is that the minute they got power back to the devices there were back up
and they touched absolutely nothing in the wiring closet.

Thanks !

Chuck
