Power Supply Module Installing a Power Supply Module 31 To install a power supply module: 1 Orient the module so that its sides enter the guides on either side of the chassis slot. 2 Slide the module into the chassis until the face panel is flush with the enclosure. 3 Secure the screws on either side of the front panel. 4 If a redundant power supply is not installed in the second power supply slot, cover the slot with a blank panel for safety.
CHAPTER 4: INSTALLING AND CONNECTING C OREBUILDER M ODULES Figure 3 Hot-Swapping a Redundant Power Supply Switch Module The CoreBuilder 7000 family ATM switch provides for a redundant switch module to ensure continued operation should the main switch module fail. For more information on the operation of the redundant switch module, see Chapter 10 in the Operations Guide.
Switch Module 33 3 Insert the card into the chassis by placing it between the guides of the selected slot and sliding the card until it stops. 4 Grab both inject handles and push them inward. This locks the card into the chassis. You may have to apply considerable pressure to the handles. An audible “click” indicates that the connectors have engaged. 5 Tighten the card’s securing screws. You are now ready to connect cables to the appropriate ports.
CHAPTER 4: INSTALLING AND CONNECTING C OREBUILDER M ODULES Figure 4 Hot-Swapping a Switch Module or Interface Module Setting up Switch Module Redundancy This section describes procedures for installing and setting up both a main and redundant switch module together. Two different setup procedures are described. The first procedure covers setting up the main and redundant switch module hardware redundancy without setting up LANE redundancy. This procedure only requires operating the LMA.
Switch Module Setting up Switch Module Hardware Redundancy 35 Use the following procedure to set up the switch module hardware redundancy. 1 Designate and mark the main and redundant switch modules. 2 Insert the switch module you marked as “redundant” in slot 2. Do not insert the switch module you marked as “main” yet. 3 Turn on the CoreBuilder 7000 family ATM switch. The switch module in slot 2 becomes active. 4 Run the Integrated Fast Setup procedure (see “Integrated Fast Setup” on page 56.
CHAPTER 4: INSTALLING AND CONNECTING C OREBUILDER M ODULES General Description of the Procedure The following is a general description of the procedure for orientation purposes only. When you perform the procedure, use the detailed steps in the following sections. 1 Install both switches in chassis and run CFGFRMAT.BAT on each one. Connect Ethernet ports of each switch module and install at least one interface card in the chassis.
Switch Module 37 2 Verify that at least one interface card of any type is installed in the CoreBuilder chassis in any interface card slots 3-6. Data is transferred between switch modules via a communications chip on an interface card. 3 Verify that the Ethernet management ports in both switches are connected to the NMS station.
CHAPTER 4: INSTALLING AND CONNECTING C OREBUILDER M ODULES e Transfer the RS-232 cable to the service port of the redundant switch module. f Repeat step d) g Transfer the RS-232 cable to the console port of the main switch module. Hardware Redundancy Setup 2 Set up the main switch module using the Integrated Fast Setup (see “Integrated Fast Setup” on page 56). Do not reboot the switch from the Integrated Fast Setup procedure (answer “no” to the prompt). The main menu appears.
Switch Module 39 ELAN names you have selected. You will need them for setting up the other switch module. 13 When finished, close the Backbone and Services window. 14 Wait one minute to allow the LECS order database to transfer to the other switch module. The LECS ELAN database does not transfer automatically. 15 Reboot the switch using the LMA menu sequence: (1) SYS / (7) RBO. The purpose of this step is to make the first switch module active in order to set up the LANE services there.
CHAPTER 4: INSTALLING AND CONNECTING C OREBUILDER M ODULES This item could be done through the LMA but it is preferred to do so through the NMS since the LMA will not show any redundant LES that exists. 22 Reboot the switch using the LMA menu sequence: (1) SYS / (7) RBO. The purpose of this step is to make the second card active in order to check the LANE services there. 23 After the second switch module boots, verify connectivity with the NMS station as in step 8).

D CABLING REQUIREMENTS This appendix addresses many aspects of installing optical fiber cabling to support the CoreBuilder® 7000 family ATM switch environment. It also deals with modem cables and Ethernet and control cables for management.
APPENDIX D: CABLING R EQUIREMENTS ■ make changes quickly ■ isolate faults in the distribution system Consult the cabling system plan to set up the cable labeling and record keeping system best suited to the environment. Also consider the following recommendations: ATM Cabling ■ Identify cables by securely attaching a label to the ends of all cables. ■ Draw a floor location grid matrix using the building floor plans. For easy reference, use this grid when assigning location numbers to cables.
ATM Cabling 111 3Com supports multi-mode fiber (MMF-PMD) 62.5/125 µm and Category one (1) single mode fiber (short reach) (SMF-PMD). When deciding whether to use multi-mode or single mode fiber, determine the maximum interstation distance (the distance from the CoreBuilder 7000 to any potential end station): Caring for Fiber Optic Transceivers ■ If the maximum interstation distance is less than or equal to 2 kilometers (1.25 miles), use multi-mode fiber (MMF-PMD).
APPENDIX D: CABLING R EQUIREMENTS Multi-mode Fiber Standards The MMF-PMD standards define the requirements for an ATM cable plant to support an interstation distance of up to 2 kilometers (1.25 miles) of multi-mode fiber. The cable plant includes all fiber optic components between any two communicating ATM devices and their associated “station-to-network” connectors at each end.
ATM Cabling 113 Table 25 Standard Multi-mode Fiber Specification (continued) Maximum distance between nodes 2 km Output power (from transmitter) 19 dB minimum 14 dB maximum Receive power 30 dB minimum sensitivity 14 dB maximum sensitivity *Maximum attenuation includes cable attenuation and the loss induced by other components such as connectors, splices, and the mating of unlike fiber types. Although some 2 km cable plants have a total attenuation of less than 11.

ATM Cabling 115 Because the resulting value, 7.85, does not exceed the maximum attenuation value, no adjustments are needed in the types of fibers joined or how they are connected. The link meets all of the specifications of the MMF-PMD. Verifying Modal Bandwidth The bandwidth of an optical fiber is the lowest frequency where the magnitude of the baseband frequency response has decreased by 3 dB compared to the magnitude at zero frequency.
APPENDIX D: CABLING R EQUIREMENTS between any two communicating ATM devices and their connectors at each end. To determine whether the cable plant complies with the SMF-PMD standard, do the following: 1 Compare the specifications of the fiber you are using to standard specifications, as described in Table 29. 2 If you mix equipment supporting Category 1 and Category 2, verify the maximum attenuation between the equipment, as described in Table 30.
