Automatic Selection of Redundant Connections
NOTE – This feature is supported only on the Alteon 180 Series Web switches.
The Alteon 180 series’ unique dual-media configuration supports automatic bring-up and failover between the 10/100 Mbps and 1000 Mbps port-pairs. Order of precedence follows these
rules:
n If both the 10/100 Mbps and 1000 Mbps ports are inactive:
o
If the user activates the Gigabit Ethernet port first (by plugging a live cable into the
SC-jack), the port immediately becomes active.
o
If the user activates the 10/100 Mbps port first, it remains inactive for a user-selectable
timeout (default 1.5 seconds). If the Gigabit Ethernet port is activated prior to the timeout, it becomes the active port. Otherwise, the 10/100 Mbps port becomes active.
n If the active Gigabit Ethernet link fails, the 10/100 Mbps port will become the active port,
with minimally required software intervention.
n If the 10/100 Mbps link is active and the Gigabit Ethernet link becomes viable (either
because of a newly created connection or because of a repaired link), the 10/100 Mbps
link will remain active until one of the following conditions occurs:
o
The 10/100 Mbps link fails or is removed by the user.
o
The user forces the Gigabit Ethernet to become the active link from any management
interface.

Troubleshooting
This section contains information about possible problems that may occur or error messages
that might display if the switch is not properly installed or configured .
Link LED Does Not Light
Symptom
The green Link LED does not light. When you check the Link state using the console terminal
(see the Web OS sw itch software manuals), the status is reported as down.
Cause
n Port configuration mismatch. If the switch port is configured with a specific speed or
duplex mode (for example, 100 Mbps , full du plex) check to s ee that the other dev ice is set
to the same configuration. If the switch port is configured to auto-negotiate, verify that the
other device is also set to auto-negotiate. Refer to the appropriate Web OS switch software
manuals for more information about setting speed and mode.
n Cable problem. Make sure you are using the correct type of cable to connect the switch to
other devices. Refer to Figure 10 on page 21 for information about crossover cables for
connecting switches, hubs, or routers to Alteon Web switches.
Temperature Sensor Error Message
The following message is displayed on the console if the temperature of an Alteon Web switch
exceeds the threshold. Immediate attention is required.
Temperature at sensor xxx exceeds threshold
Current temperature is xx
Actions
n Make sure that the air circulation vents on the front, back, and sides of the switch are free
from obstruction by cables, panels, rack frames, or other materials.
n Make sure that all four cooling fans inside the switch are running. The fans are located
behind the ventilation grill at th e rear of the swi tch. The exhaust from all four fans should
be blowing outward with roughly equal air pressure (it is normal for the exhausts to have
different temperatures). You can also use a flashlight to check whether the fan blades are
moving. If any fan stops during switch operation, contact Customer Support.
