d. Save and Exit BIOS setup.
5. Does the 2074 operating system appear "hung"? The 2074 ships with an OS/2
screen saver that displays a color picture of a lighthouse after 20 minutes. The
2074 ships without a password. To clear this screen, just press "ENTER". If the
customer has added a password, you will need it. Ask the customer for the
password. If the customer doesn't remember the password or wants the
password removed, you will have to reload the 2074 code from the load CD.
Please refer to Chapter 3, "Service Procedures" to reload the 2074 code. If
you can't clear the logo because the 2074 appears "hung", please refer to the
section titled "Troubleshooting 2074 Hang Conditions".
6. Check the LAN adapters LEDs and the ESCON LED display. For the Token
Ring LEDs description see Table 2-2 on page 2-14. For the Ethernet PCI
adapter in slot 3, see Step 9 under "Token-Ring or Ethernet LAN adapter
diagnostics" on page 2-18.
Note: If more than one LAN adapter (NIC) is in use (cable attached to it),
question why they are doing this. Unless the customer "really"
understands networking and route statements, only one NIC should be
enabled. Unlike Windows
two NICs cannot be on the same subnet. Maybe this is the source of
the problem.
A quick guide is (only check LAN adapters that have cables attached):
v Token Ring adapters should have the green LED on solid. If lights are not
correct, go to network checkout "2074 LAN Adapter Diagnostics" on page
2-16.
v The on-planar Ethernet card should have the 'LINK ON' indicator on in the
rear RJ-45 connection. There is also a Transmit/Receive LED for this card
located on the Operator Information Panel. There is no LED indicating link
speed for the on-planar Ethernet. If you suspect there may be a problem
with this card, go to network checkout "2074 LAN Adapter Diagnostics" on
page 2-16.
v The Ethernet PCI adapter in slot 4 has both a Link status and a Link Speed
LED. If you suspect that there may be a problem with the Ethernet PCI
adapter to network, checkout "2074 LAN Adapter Diagnostics" on page 2-16.
v For ESCON1 cards, if the channel is online, the top and bottom LEDs
should be green. If not, refer to "ESCON Troubleshooting" on page 2-11
v For ESCON2 cards, the LED display should read "On-line". If not, refer
to"ESCON Troubleshooting" on page 2-11.
7. Using the steps outlined under "Determining Whether the 2074 Channel
Adapters Are Active" on page 3-3, verify that the states of the channel adapters
are correct.
8. From an OS/2 Window execute the command CHECKPCI. Did it pass? There
should be nothing in red. If no, verify why the PCI adapters aren't where they
belong. This will verify that unknown adapters aren't installed and that none
are missing. If adapters are missing, the LAN card numbering will be incorrect.
This is not acceptable.
Note: For the 2074 Model 003, Slot 1 should always be empty.
9. Now would be a good time to check for dumps:
Note: From an OS/2 window, type the command "DATE" and if this is different
from the actual, report this to the next level of service, prior to
correcting. Repeat for the "TIME" command. It is important to report
®
