Power-On Checkout
Step
1. The 8270 automatically performs diagnostics when it is connected to a
powered on. Diagnostics can last up to 8 minutes. You can get some
idea about the progress of the diagnostics by observing the OK (green)
and Fault (unlabeled) LEDs (amber) on the Token-Ring Processor Card.
During the diagnostic period, the OK LED and the Fault LED blink in
unison. If the diagnostics complete successfully, the Fault LED is off, and
the OK LED is on. In addition, OK is displayed in the 4-character status
display for 2 minutes.
Verify that the Fault LED (amber) on the processor card is off. If the
Fault LED is on, press the Reset button. If the Fault LED remains on,
the processor card is defective; contact your place of purchase.
Step
2. If a UFC has been installed and cabled, there are status LEDs that
should be observed and verified on the UFC faceplate. Refer to the
documentation provided with the UFC for information regarding the
operation and status of the UFC.
Table 2-2 summarizes the normal state of the Status LEDs on the power supply,
the Token-Ring Processor Card, and the UFCs after a successful power-on
sequence.
If the LEDs are not in the normal state, go to Chapter 5, “Troubleshooting and
Service.”
Note: UFC Slot 1 on the 8270-800 is intended for use with UFCs having two or
fewer ports. If a 4-port UFC is intentionally installed in slot 1, ports 3 and 4 will not
operate and the LEDs for those ports will not be on. In addition, the message S1X
is permanently displayed in the 4-character status display. All other ports will
operate correctly.
If diagnostics have been completed successfully and all of the LEDs are in the
normal state, physical installation of the 8270 is complete.
To continue with the installation, go to Chapter 3, “Setting up a Console Session.”
