Troubleshooting LAN/9000
100Base-T Checklist
• If the card is not an EISA 100Base-T card, set the card to
Auto-Negotiation mode. This can be done temporarily with the
command:
lanadmin -X AUTO_ON nmid/ppa
or permanently by removing any manual settings for this port in the
/etc/rc.config.d/ eisa configuration files. Refer to Table 3-3 for correct
configuration file.
• If problems persist, if a switch is used, manuallyset the switch port to
the desired speed and duplex.
• Manually set the card to the desired speed:
- for 100Base-T hubs: 100 Half Duplex
- for 10Base-T hubs: 10 Half Duplex
• Manual setting can be done temporarily with the command:
lanadmin -X speed/duplex nmid/ppa
• Manual setting can be permanently set by modifying the
configuration file in /etc/rc.config.d or by using SAM (recommended
way). Refer to Table 3-3 for correct configuration file.
• If problems persist: connect the card to a switch or hub that is known
to be good.
• If this connection works, contact the Response Center with
Switch/Hub information. This may be an IOP (Interoperability)
problem.
• If this connection fails, the card may be bad and may need to be
replaced.
