Hi Folks
I have an old telnet power switch. When I connect it directly to a Cisco Catalyst C2960X, I cannot ping it. When I put an unmanaged (dumb) switch in between, I can ping it. I tried a cross-over cable, but that did not help. I tried adding the extra config statements, beyond the vlan 52 lines, one at a time to no avail. Here is the config:
switchport access vlan 52
switchport mode access
switchport nonegotiate
power inline never
speed 10
duplex half
no mdix auto
spanning-tree portfast
How do I make a Cisco port act like a dumb switch?

Can you define what you mean by a "telnet power switch"?
Also, when you connect it directly to the C2960X, what is the interface status on the Cisco?

It is a WTI TPS-2 network power switch. We can telnet or ssh into the box to control the power of other devices. Those devices can be rebooted, powered off, or powered on remotely. After a power outage, there are settings that permit it to have a delayed start. From their website:
"Electronic equipment sometimes 'locks-up', requiring a service call just to flip the power switch to do a simple reboot. The TPS-2 Telnet Power Switch gives you the ability to perform this function from anywhere on the LAN/WAN..."
The status is up when connected to the Cisco directly. The logs did not provide any information either sadly.

Just checking, you tried connecting without all those other configs?
Only -
switchport access vlan 52
switchport mode access
spanning-tree portfast
If so, maybe try changing the the auto negotiation to allow only 10Mb
speed auto 10
duplex auto full (or half if you think that may work.)
