Troubleshooting a Communications Port Connection

If the startup diagnostic message does not appear on your console when the hub

is reset or powered on, verify the following items:

• All hubs are powered on.

• The cable you are using is correct and is ﬁrmly seated in the correct ports.

To verify your cable, see “Communications Port” on page 1-6.

• Your device has been correctly conﬁgured for your console or modem.

If the diagnostic message displays, but the system test fails, replace the hub and

contact your point of purchase for service. For more help with installation and

conﬁguration of BayStack 100-series hubs, see “Bay Networks Customer

Support” on the inside front cover of this using guide.
