 Why not put a new UPS at one or two of the key terminals in each remote
location?  I'd see no reason to add a terminal in a dark closet.

Hi Folks,

We have 8 remote locations all tied back to our AS/400 here at corporate
via Frame Relay. The devices at each remote site consist of a Cisco
router, a Perle control unit with NIC card, etc. We use TCP/IP to
connect everything. Then there are either hubs or switches depending on
the size of the site. All of this is in a rack in a wiring closet and it
is all protected by an APC rack mount UPS.

The end user devices consist of dumb terminals and printers as well as
PC's with the Synapse emulation product.

So we take a power hit and ALL user devices drop - since there is no UPS
protection for any of them - but the communications stuff stays up. BUT,
the APPC sessions for the control unit(s) drop and eventually reset once
a user device comes back up power-wise.

So I assume in a configuration like this that the control until polls
for ANY device and all is OK if it finds one, otherwise it "drops" ?

I ask, because it would be REAL easy to stick a dumb terminal in the
wiring closet, attached to the UPS, etc. so there would ALWAYS have a
user devices with power (?).

This would eliminate the 10+ minute "recycle" time at the larger
branches when they have a power problem.

Can anyone confirm this ?

Thanks !
