48 PCI ESCON Adapter Installation Guide
STEP
1. With your server powered on, check to make sure both LEDs arelit. Ifthe top
LED is Green and the bottom LED is Orange then the adapter has successfully
completed POST and loaded firmware. This is the normal condition prior to
starting the software. The adapter is operational. The bottom LED will remain
Orange until the server is varied online at the mainframe console.
Proceed to the troubleshooting section on ESCON configuration. If either LED is
off, power down your server, remove the adapter, and re-install it. Make sure the
adapter is properly seated in the slot. Power the server back on. If the LED(s)
remain unlit, contact your service provider.
2. When your server is first powered on both LEDs will briefly turn Red. When the
adapter starts running Power On Self Test (POST) the top LED will illuminate
Yellow. Once POST completes, the top LED will illuminate Green if POST was
successful or Red if POST failed.
Watch the top LED as your system powers up. Verify the top LED goes from
Red to Yellow to Green. If the top LED remains Red or turns Yellow and then
Red again the adapter is not working properly. Power down your server and re-
install the adapter. Power the server back on. If the condition repeats itself
contact your service provider.
If the top LED is Yellow and the bottom LED is Red wait for 5 minutesto s eeif
the status changes.
3. When the top LED turns Green,P OSThas completed. Theadapt er’s Intel960
processor will then load the device emulation (either 3172 or 3174). The bottom
LED indicates the status of the emulation.
When the adapter is first powered on the bottom LED should be Red. This is a
normal indication that the emulation has not loaded. The LED will remain Red
while POST runs. Once the top LED turns green, indicating POST has been
successful, the bottom LED should quickly turn Orange.
If the top LED is Green and the bottom LED is Red wait for one minute. If the
bottom LED remains Red, the emulation has not successfully loaded. Perform a
hardware reset (or Power Off / Power On) of your server. If the problem persists
contact your service provider.
4. If you have checked your software configuration and arestill not able to vary the
system online, check your ESCON cable. Make sure both ends are properly
seated. Unplug both ends. Plug them back in. Be sure you hear them click when
you insert them into the connector.
