Cabling the NET MGMT Port on the AT-SBx31CFC960 Card

The controller card must have access to your network to support the
management features in Table 22 on page 74. You can give the controller
card access to your network either by configuring the Inband Interface,
which allows the card to use the backplane and line cards to communicate
with your network, or connecting the NET MGMT port to a network device,
such as a switch, router, or workstation. (For instructions on how to
configure the Inband Interface, refer to the Software Reference for
SwitchBlade x3100 Series Switches.)
Note
The controller card has an Easy Startup application that lets you
perform the initial configuration of the chassis using a web browser.
If you plan to use the application, you should not connect the NET
MGMT port to your network at this time. Instructions in Chapter 10,
"Verifying the Hardware Operations of the Chassis" on page 209
explain how to use the Easy Startup application with the NET MGMT
port.
Here are the guidelines to using the NET MGMT port:
The cabling requirements of the port are the same as the ports on
the AT-SBx31GT24 Line Card, in Table 13 on page 54.
If the chassis has two AT-SBx31CFC960 Line Cards, connect the
NET MGMT ports on both cards to network devices so that the
inactive card can perform the management functions if it becomes
the active card.
The port uses Auto-Negotiation to set its speed and duplex. You
may not disable Auto-Negotiation. If you connect the port to a
network device that does not support Auto-Negotiation, it defaults
to 10 Mbps, half-duplex mode. To avoid a speed or duplex mode
mismatch, connect the port only to a device that also uses Auto-
Negotiation.
You may connect the NET MGMT port to a port on one of the
Ethernet line cards in the chassis so that the controller card
communicates with your network through the line cards. However,
you can achieve the same result by configuring the Inband
Interface instead, as explained in the Software Reference for
SwitchBlade x3100 Series Switches.
The wiring configuration of the port is set automatically with automatic
MDIX detection. You may not disable automatic MDIX detection. For
automatic MDIX detection to work successfully, the network device you
connect to the port must also support the feature. If it does not, the NET
MGMT port defaults to MDIX. This may entail the use of a crossover
