[comp.protocols.appletalk] Vanishing Laser II NTX

EXZ@PSUVM.BITNET (06/22/89)

We've had a problem with LaserWriter II NTXs vanishing from the network;
suddenly they are no longer visible as network devices. Power cycling
the Laser brings it back.

Our configuration is as follows: PhoneNet-based AppleTalk internet
consisting of 4 networks, each in it's own zone, linked by InterBridges.
Starcontrollers are used to link nodes; each branch has 1-6 devices on it,
each branch is terminated with a resistor.

We have 2 LaserWriter II NTXs that are vanishing. No problem with NTs.

Has anyone seen this problem?  Please reply by email & I'll summarize.
