       Standalone Ethernet Board Description

  The PortMaster 4 supports two standalone Ethernet boards: a single-interface board and a dual-interface module. The single-interface board can be inserted into any slot--except slot 4, which is reserved for the manager module. The dual-interface standalone Ethernet module, which consists of two boards, must be inserted into slot 3 because slot 3 has more backplane width. A single PortMaster 4 can have only one dual-interface Ethernet module.

       Numbering of Standalone Ethernet Interfaces

  The interfaces on a standalone Ethernet board or module have two-digit numbers that correspond to the slot in which they are installed:

•  On a dual-interface Ethernet module, the interfaces are always numbered Ether30  and Ether31  because the module must be installed in slot 3.

    Although physically installed in slot 3, the Ether31 interface is monitored and reset thorough virtual slot 11.

•  On a single-interface Ethernet board, the interface can be have any of the following numbers because this board can be installed in any slot except slot 4: Ether00, Ether10 , Ether20, Ether30, Ether50, Ether60, Ether70, Ether80 , or Ether90 .

       Standalone Ethernet Characteristics

  The standalone Ethernet interfaces have the following characteristics:

•  Communicate with the manager board over the passive ATM backplane
•  Supported by a CPU for inbound data and a CPU for outbound data
•  Are generally used to configure network traffic

       Installing a Standalone Ethernet Board

  Follow these instructions to install a standalone Ethernet board.

  Note ¯ Because the Ethernet board is hot-swappable, you can install it while the PortMaster 4 is turned on and running.

 

Procedure

  Warning ¯ To avoid damaging the internal components of the PortMaster 4, follow antistatic precautions by wearing a grounding wrist strap. See "Grounding Wrist Strap Instructions" on page 2-3.

  1. Line up the edge of the board with the card guide in the appropriate slot.

  ¯ If you are installing a single-interface Ethernet board, you can use any slot except slot 4 (Figure 7-1).

  ¯ If you are installing a dual-interface Ethernet module, you must install it in slot 3.

  Slots are numbered 0 through 9 from left to right. Slot 4 is reserved for the manager module.

  Figure 7-1 Installing a Standalone Ethernet Board

  2. Insert the board in the slot and gently guide it into the slot.

  If you have trouble sliding the board into the card guide, gently wiggle it back and forth to help it slide in.

  3. When the board is completely inserted in the slot, close the top and bottom tabs so they are flush with the face of the chassis.

  Closing the tabs causes the board to connect with the backplane.

  4. After you finish installing boards or modules in the PortMaster 4, ensure that every slot contains either a working board or blank board.

  See "Cover Empty Slots with Blank Modules" on page 2-20.

       Connecting an 10/100BaseT Ethernet Cable

  A standalone Ethernet board has the following Ethernet connections:

•  10/100BaseT--The single Ethernet board has one RJ-45 interface (labeled Ethern0 in Figure 7-2), and the dual Ethernet module has two (labeled Ether30 and Ether31).
•  Media-independent interface (MII)--This interface is used to connect other wiring types (copper or fiber, for example) to the 10/100BaseT Ethernet. Devices attached to the MII interface must be MII-compliant. The single Ethernet board has one MII, and the dual Ethernet module has two (labeled alternative Ether30 and alternative Ether31).

  If both the RJ-45 interface and MII are connected, the PortMaster 4 uses the MII.

  Figure 7-2 Single-Interface and Dual-Interface Ethernet Board s

 

  Follow these instructions to connect an Ethernet cable to the Ethernet 10/100BaseT interface.

 

Required Equipment

  One of the following:

  o Category 5 twisted pair cable, as specified by the EIA/TIA-568-B wiring standard, with an RJ-45 connector (See "RJ-45 Cable" on page A-2 and "Ethernet Cable Specifications" on page A-3 for more information.)

  o MII cable with an MII connector

 

Procedure

  1. Remove the cover from the cable guide, if necessary.

  2. Run the cable through the cable guide duct until it is directly over the standalone Ethernet board or module.

  3. Pull the cable through the fingers of the cable guide duct as shown in Figure 7-3.

  Figure 7-3 Pulling a Cable through the Cable Guide

  4. Connect the cable to the Ethernet RJ-45 connector or MII connector (see Figure 7-2).

  5. Verify the following LED behavior:

  a. The PWR LED at the bottom of the board or module is solidly lit.

  b. The amber DIAG LED at the bottom of the board blinks three times per second during startup and then stays solidly lit with a 1-second interruption every 5 seconds.

  DIAG LED behavior might vary according to the version of ComOS you are running.

  c. The green link LED next to the RJ-45 interface is solidly lit for each Ethernet connection.

  d. The amber network LED next to the RJ-45 interface blinks when Ethernet traffic is present.

  See "Troubleshooting LEDs on a Standalone Ethernet Board" on page 7-5 if any LED fails to behave properly.

  6. If you have finished inserting modules and boards and connecting lines, replace the cable guide cover by squeezing the duct fingers together with one hand, and sliding the cover over the duct fingers with the other.

       Troubleshooting LEDs on a Standalone Ethernet Board

  Figure 7-1 identifies problem-indicating LED behavior on a standalone single-interface Ethernet board or dual-interface Ethernet module, possible causes of the behavior, and possible solutions.

  Table 7-1 Standalone Ethernet Hardware Problems and Solutions  

 

Problem	Possible Cause	Possible Solution
All LEDs fail to light.	Power is not present.	Check the power switch, power cable, outlet, and fuse. For instructions on checking and changing the fuse in the AC version, see "Replacing a Fuse" on page 4-10.  Contact Lucent InterNetworking Systems Technical Support if power is not present on the DC version.
Amber DIAG LED on a standalone Ethernet board does not light.	Board malfunction.	Contact Lucent InterNetworking Systems Technical Support.
During startup, the DIAG LED on a standalone Ethernet board fails to light, stays lit, or blinks three times per second continuously.	A hardware problem has occurred.	Contact Lucent InterNetworking Systems Technical Support.
During operation, the DIAG LED on a standalone Ethernet board stays solidly lit or does not light.	A hardware problem might have been caused by an external device.	If the LED stays solidly lit or does not light after you have removed all external devices, contact Lucent InterNetworking Systems Technical Support.
Link LED on a standalone Ethernet board is not lit when connected to a 10/100BaseT Ethernet hub.	There is no link integrity.	Check the connection to the hub.
Network (amber) LED on a standalone Ethernet board is solidly lit.	Heavy traffic can cause the network LED to blink so rapidly that it appears to be solidly lit.  However, if packets cannot be passed, you might have an incorrectly cabled network.	Verify that the network cabling is correct.
Network (amber) LED on a standalone Ethernet board is not lit.	If the PortMaster 4 is not receiving, or sending traffic, the network LED is not lit.	Verify that the network cabling is correct.
An undefined problem occurred at startup, but the cause cannot be determined from LED behavior.	Refer to the solution column.	Try booting in console mode, and observe the boot messages. See "Observing Boot Messages" on page 4-3. If the boot messages do not suggest a solution, record the information and contact Lucent InterNetworking Systems Technical Support.

       Replacing a Failed Board

  In the event of a board failure, you can replace a failed board with a functional one without having to reconfigure the new board. The configuration is attached to the slot in which the board resides. See "Replacing a Failed Module or Line Board" on page 4-7 for instructions. The configuration settings reside in the system manager board. Nonvolatile RAM is loaded when you insert the board and turn it on with the set Slot0 on command.
