Appendix
9H423-26 Module Specific
Information
Introduction
This appendix contains local management information that is specific to the
9H423-26 Fast Ethernet Switch Module.
The 9H423-26 Switch Module has 26 ports:
• 24 ports (two fixed RJ21 connectors)
• 2 ports (two fixed MMF SC connectors)
This module can operate in either full duplex or half duplex mode.
Auto-negotiation provides support for 10 Mbps and 100 Mbps speeds at both half
and full duplex. 100Base-FX supports 100 Mbps speed at both half and full
duplex.
Auto-negotiation allows the module to automatically use the fastest rate
supported by the device at the other end (either 10 Mbps or 100 Mbps at either
half or full duplex). This technology is similar to how modems negotiate
transmission speed to find the highest transmission rate. Similarly,
auto-negotiation determines the highest common speed between two devices and
communicates at that speed. If no common speed is detected, the device will be
partitioned.
Modifying Fields and User Privileges
To modify fields on this module, you must have read-write or super-user
privileges. If you have read-only privileges, you can view information; however,
you cannot modify any fields. For more information about user privileges and
community names, see the SmartSwitch 9000 Module Local Management User’s
Guide.

Port Configuration Screen
The 9H423-26 Port Configuration Screen (Figure 1), displays configuration
information about each port on the module (one port at a time).

Port Configuration Screen Fields
The following information briefly explains each Port Configuration Screen field.
Slot # (Modifiable)
Indicates the slot that the board occupies in the chassis.
Port # (Read-only )
Indicates the current port for which statistics are displayed.
PortType (Read-only)
Displays one of the following values:
• MMF SC
• RJ21
Link Status (Read-only)
Displays one of the following values:
• Link
• No Link
• N/A
Current Operation Mode (Read-only)
Displays one of the following values:
• 10Base-T
Operating standard 10 Mbps Ethernet over two pairs of UTP cable.
• 10Base-TFD
Operating Full Duplex 10 Mbps Ethernet over two pairs of UTP cable. Full
Duplex indicates the module is connected to a single device, and is not
listening for other transmissions or collisions when sending data. This allows
both devices on the link to send and receive data simultaneously over the link.
Theoretically, this provides the devices with twice the bandwidth of normal,
or half duplex, Ethernet.
• 100Base-TX
Operating Fast Ethernet over two pairs of Category 5 UTP or Type 1 STP
cable.
• 100Base-TXFD
Operating Full Duplex 100 Mbps Fast Ethernet over two pairs of Category 5
UTP or Type 1 STP cable.
• 100Base-FX
Operating 100 Mbps Fast Ethernet over two strands of multimode fiber cable.
• 100Base-FXFD

9H423-26 Module Specific Information
6
Operating Full Duplex 100 Mbps Fast Ethernet over two strands of multimode
fiber cable.
Desired Operation Mode (Toggle)
Displays one of the following values:
• Auto-Negotiation
• 10Base-T manual
• 10Base-TFD manual
• 100Base-TX manual
• 100Base-TXFD manual
• 100Base-FX manual
• 100Base-FXFD manual
Only the modes that the device is capable of using are displayed. The module
defaults to auto-negotiation. If the device connected to the module also supports
auto-negotiation, the devices self-configure to the fastest possible speed and
duplex. For example, if the other device does not support auto-negotiation, the
devices do a parallel detection and configure to either 10 Mbps or 100 Mbps, but
only at half duplex. If the device connected to the module is standard Ethernet
with no auto-negotiation support, and is configured for full duplex, the Desired
Operation Mode field must be set to 10Base-T Full Duplex.
Advertised Ability (2 Toggles)
Allows the user to specify the advertised ability for the chosen port. The ability of
each port is presented first, followed by the ability to enable/disable on each port.
Advertised Ability is applicable only when the Desired Operation Mode field is
set to Auto-Negotiation. Otherwise this field displays N/A and is read-only.
When in auto-negotiation mode, the module auto-negotiates to the highest speed
being advertised by both devices.
Port # (Modifiable)
Displays the current port for which configuration information is displayed. Use
the procedure in the next section to display configuration information for a
different port.
