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 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

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.
