Question on Perle 494 Control Unit/Communications...

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
