pinouts, refer to “Connectors and Port Pinouts” on page 102.
The default setting for the Management port is Auto-Negotiation with Auto
MDI/MDI-X. At the default setting, the port, which is IEEE 802.3u
compliant, sets its speed and duplex mode automatically with Auto-
Negotiation. You can disable Auto-Negotiation and set the speed and
duplex mode manually.
The wiring configuration of the port is set automatically with
Auto MDI/MDI-X to MDI or MDI-X, depending on the wiring configuration
of the end node. This allows you to use a straight-through twisted-pair
cable regardless of the wiring configuration of the port on the network
device. The Auto MDI/MDI-X feature is only available when the port is
using Auto-Negotiation. If the Auto-Negotiation feature is disabled with the
Switchblade x3112 Management Software, the port defaults to the MDI-X
setting.
NET MGMT LED
The Network Management (NET MGMT) port on the AT-SBx31CFC
Fabric Control Card has one Status LED as displayed in
Figure 8 and
described in Table 5.
Console (RS-232)
Port
You use this port for local management with a console or a PC with a
terminal emulation program. See
Figure 8. This port does not require the
AT-SBx31CFC Fabric Control Card to have an Internet Protocol (IP)
address and is referred to as local or out-of-band management because it
is not conducted over a network.
When initially configuring your SwitchBlade x3112 Switch, you first
connect to this port with an RS-232 Serial Management cable. The cable
is provided with the AT-SBx31CFC Fabric Control Card.
For instructions on how to start a local management session, refer to
Chapter 2, “Starting a Local Management Session” on page 87 or refer to
the Software Reference for SwitchBlade® x3100 Series Switches on the
ATI web site. Go to
“Where to Find Web-based Guides” on page 13 for
