NetStructure™ 480T Routing Switch User Guide
How do I remove unused default and static routes?
• If you have defined static or default routes, those routes will
remain in the configuration, independent of whether the VLAN and
VLAN IP address that used them remains. You should manually
delete the routes if no VLAN IP address is capable of using them.
What if I forget my password and cannot log in?
• If you are not an administrator, another user having administrator
access level can log in, delete your user name, and create a new
user name for you, with a new password.
• Alternatively, another user having administrator access level can
log in and reset the device to factory defaults. This will return all
configuration information (including passwords) to the initial
values.
• If no one knows a password for an administrator level user, contact
Intel Customer Support. See “Intel Customer Support” on
page 461.
Port Configuration
What if no link light shows on a 100/1000 Base port?
• If patching from a hub or switch to another hub or switch, ensure
that you are using a CAT5 (Category 5) cable. A crossover cable is
recommended and is required for some configurations.
What if I’m receiving excessive RX CRC errors?
• When a device with autonegotiation disabled is connected to a
480T routing switch that has autonegotiation enabled, the switch
links at the correct speed, but in half-duplex mode.
The switch 100/1000 Mbps physical interface uses a method
called parallel detection to access the link. Because the other
network device is not participating in autonegotiation (and does
not advertise its capabilities), parallel detection on the switch is
only able to sense 100 Mbps versus 1000 Mbps speed, and not
the duplex mode. Therefore, the switch establishes the link in
half-duplex mode using the correct speed.
