xii 2216 Maintenance Manual

Chapter 1. Problem Determination
Note: The 2216 service representative will need to have the diagnostics run
remotely by the operator at a station connected via the modem. Alternatively, the
servicer can run the diagnostics on site through an ASCII terminal connected
directly to the 2216.

2216 Power Supply
The power supply panel contains:
¹The power switch, which is used to power ON or OFF the 2216
¹The Overcurrent Reset switch, which resets all current-limit circuits for the
+12 V and -48 V outputs at the same time.
System Card LEDs
After power-on-reset (POR), the green and yellow LEDs will remain on until
successful completion of the power on tests (which will be under 2 minutes). The
green LED will begin blinking, which indicates that the code is being loaded into
memory. The green LED will be switched on to indicate that the system code is
operational.
Note: If the 2216 is waiting for the power-on password, the green LED is off. If
you do not have the console attached, you will not know that the system is waiting.
Looking at the LEDs may lead you to believe that you have a hardware problem.
 Copyright IBM Corp. 1997 1-1

LED Indicators The IBM 2216 has a number of light-emitting diodes (LEDs) that indicate how the
unit is functioning.
Figure 1-1. Power Supply, System Card, and Adapter Card LEDs
1-2 2216 Maintenance Manual

Power Supply Status
LEDs Meaning
Yellow
(Overcurrent) On - There is an overcurrent condition with the −48 V to one or more of the adapters (slots 1–8) or the +12 V to the fan tray.
Green DC On - +5 V, +12 V, and −48 V are OK.
Green AC On - AC source voltage is present and within tolerance.
System Card Status
LEDs Meaning
PCMCIA 1 or
PCMCIA 2
(Yellow)
On - PCMCIA device has a fault, is not installed, or is not seated
correctly.
Off - Device passed self-tests
OK (Green) On - Card hardware is operating normally.
Blinking - Loading from hard file
OK (Yellow) On - Card hardware has a fault.
Fault Hard Drive
(Yellow) On - Hard drive has failed.
Adapter Card Status
LEDs Meaning
OK (Green) On - Adapter is operational.
OK (Yellow) On - Adapter has a fault.
Wrong slot
(Yellow) On - Adapter is in the wrong slot.
The wrong slot LED is ON only when an adapter that is plugged into
the 2216 violates the plugging rules described in Appendix E,
“Adapter Plugging Defaults” on page E-1.
Green port1On - Port is operating normally (enabled and configured).
Off - Port is not configured or is disabled.
For the ESCON adapter:
Blinking - The optical power measurement test is running.
Yellow port1On - One or more ports has a hardware fault.
Blinking - One or more ports has a port I/O or network failure. Use
the Maintenance Analysis Procedures (MAPs) to isolate.
Off - No problem detected.
Important Phone Numbers
Contact Name Telephone Number
System Administrator:
Service Representative:
1The port LEDs of the multiport WAN adapters (FC 2282, FC 2291, and FC 2292) reflect the status of one or more of the ports.
Chapter 1. Problem Determination 1-3

Troubleshooting
Both hardware and software (operational code and configuration) problems can
affect the IBM 2216. Light-emitting diodes (LEDs), diagnostic programs, and error
messages provide information needed for problem determination. This manual is
chiefly concerned with diagnosing and correcting hardware problems. Chapter 3,
“Accessing the 2216” on page 3-1 has information about accessing the IBM 2216.
Diagnosing Hardware Problems
Generally, errors that occur before the operational code is loaded are
hardware-related. Light-emitting diodes (LEDs) on the front of the IBM 2216
indicate how the hardware components are functioning.
Go to “LED Indicators” on page 1-2 for LED status and indicators for the IBM 2216.
See “2216 FRU Exchange” on page 2-3 for information on removal and
replacement procedures for field-replaceable units (FRUs).
See Chapter 4, “Using 2216 Firmware” or Chapter 5, “Using Operational
Diagnostics” (depending on how you are connected to the IBM 2216) to run
hardware diagnostics
before the IBM 2216 has been configured.
Diagnosing Operational Code and Configuration Problems
Generally, errors that occur after the operational code is loaded indicate problems
with the operational code or configuration file.
Error codes and corrective action are described in the
Event Logging System
Messages Guide .
See Chapter 4, “Using 2216 Firmware” or Chapter 5, “Using Operational
Diagnostics” to run diagnostics
after operational code and configuration files have
been loaded.
