Maintaining the LightStream 100 ATM switch involves adding additional LINF cards for connected additional devices, replacing LINF cards, upgrading the software and moving equipment. This chapter describes the following procedures you perform on your LightStream 100 ATM switch:
The procedures in this chapter are meant for the expert user. If you are not experienced with hardware setup or have not previously used this type of equipment, when necessary refer to the chapter "Installing the LightStream 100 ATM Switch" for more information and figure references.
This section provides the procedures for adding a LINF card to the line slot of the LightStream 100 switch main unit.
Have the following equipment available when you are adding a LINF card:
Perform the following steps to open the chassis:
Step 1 Provide protection against static electricity.
Step 2 Set the console terminal power switch to the OFF (O) position.
Step 3 Set the power switch on the back of the LightStream 100 main unit to the OFF (O) position. The Power LED goes OFF. Unplug the power cable from the power outlet.
Step 4 Remove all optical cables and the EIA/TIA-232 cable by grasping the connector from the LightStream 100 front panel. Mark the cables with their respective slot numbers to facilitate reconnection later.
Step 5 Remove the cover. (Refer to the section "Removing the Cover" in the chapter "Installing the LightStream 100 ATM Switch" for detailed instructions.)
Perform the following procedure to install the LINF card:
Step 1 Ensure the jumper switch on the LINF card (P-8X79) does not differ from its initial setting. If it does, return the switch to the initial setting indicated in Figure 3-7.
Step 2 Install the LINF card. See Figure 3-8 in the chapter "Installing the LightStream 100 ATM Switch."
Perform the following steps to replace the chassis cover:
Step 1 Replace the cover. (Refer to the section "Replacing the Cover" in the chapter "Installing the LightStream 100 ATM Switch" for detailed instructions.)
Step 2 Reconnect the optical cables removed earlier.
Step 3 Connect the optical cable for the new LINF card to the slot on the front of the LightStream 100 main unit.
Step 4 Connect the new optical cable to the other device (such as a router or terminal equipment).
Step 5 Reconnect the EIA/TIA-232 cable to the EIA/TIA-232 connector on the LightStream 100 front panel. Connect the other end to the console terminal. Make sure the communication parameters of the console terminal are set correctly. (Refer to the section "Setting Communications Software Parameters" in the chapter "Installing the LightStream 100 ATM Switch.")
Step 6 Reconnect the power cable to the power outlet.
Step 7 Set the power switch on the back of the LightStream 100 switch to the ON (|) position. The LightStream 100 switch will start to execute a self-diagnostic test.
Step 8 Confirm that no hardware configuration item indicates "NG" (no good) and that "Not Installed" is not indicated for a slot on which the LINF card is installed.
To set the system configuration data, follow these steps:
Step 1 Enter show interface to display data for LINF cards installed in the LightStream 100 switch.
Step 2 Confirm that the line number of the newly installed LINF card displays. If the line number does not display, either the LINF card is improperly installed or a LINF hardware error exists. Turn OFF the LightStream 100 switch power switch and check the card.
Step 3 Enter enable to enter privileged command mode. The system requests a password.
Step 4 Enter the privileged password. The prompt changes from > to #.
Step 5 If the LINF initial settings require changing, enter the following commands:
Step 6 Enter the pvc establish command to set a point-to-point PVC connection.
Step 7 If setting PVC multicast, enter the following commands:
Step 8 If using SVC service, enter the route add command to set the SVC.
Step 9 Enter the save command to save configuration data.
Step 10 Enter the exit command to exit the privileged mode and return to the normal mode. The prompt changes from # to >.
To verify that no error messages occurred during the process of changing the configuration data, enter the following commands:
Step 1 Enter the show alarm command to display all alarms occurring in the LightStream 100 switch. Ensure only the prompt displays at the console terminal; the output message displays only when an alarm is detected.
Step 2 Enter the show line command to display line interface alarms. Confirm that GOOD displays for each installed LINF card.
This section provides the procedures for increasing lines by connecting the LightStream 100 switch with another LightStream 100 switch or another device.
Have the following equipment available when adding a device:
When connecting the LightStream 100 ATM switch with another LightStream 100 switch or another device, designate one of the the LightStream 100 switches as either the master or slave to set the synchronization between the devices. With the master setting, the transmission data of the STS-3c/STM-1 LINF card installed in the LightStream 100 switch transmits after it is synchronized to the self-running clock generated in the device. With the slave setting, transmission data transmits after it is synchronized to the data received by the STS-3c/STM-1 LINF card installed in slot 0 of the LightStream 100 switch.
The following sections provide connection methods for a LightStream 100 switch designated as the master and for a device other than the LightStream 100 switch designated as the master.
When interconnecting switches, keep in mind that the LINF card passing clocking signals can be installed in any slot on the switch; the LINF card receiving clocking signals must be installed in slot 0.
Prepare the master LightStream 100 switch for interconnecting to a slave LightStream 100 or other device by performing the following steps:
Step 1 Provide protection against static electricity.
Step 2 Set the console terminal power switch to the OFF (O) position. Disconnect the EIA/TIA-232 cable connected to the console terminal from the switch's front panel.
Step 3 Set the power switch on the back of the main unit to the OFF (O) position. Unplug the power cable from the power outlet and then from the LightStream 100 switch.
Step 4 If connected, disconnect all the optical cables and the EIA/TIA-232 cable from the front of the main unit. Mark the cables with their respective slot numbers to facilitate reconnection later.
Step 5 Remove the cover from switch. (Refer to the section "Removing the Cover" in the chapter "Installing the LightStream 100 ATM Switch" for detailed instructions.)
Step 6 Install an STS-3c/STM-1 LINF card into any slot (except slot 0). This card can be used for connecting with other devices or another LightStream 100 switch. Make sure that the LINF card is securely fixed to the LINF stopper at the rear of the unit. Install an STS-3c/STM-1 LINF card for each direct connection to another device or LightStream 100 switch.
Step 7 Match the screw holes on the LINF card with the screw holes on the LightStream 100 units. Insert the screws and fasten them using the standard screwdriver.
Step 8 Remove the front panel (without the window) from the slot where the LINF card is installed.
Prepare the slave LightStream 100 switch for interconnecting to other LightStream 100 switches. The slave LightStream 100 switch can be directly connected to a master LightStream 100 switch (from which it receives clocking signals) or it can be indirectly connected to a master LightStream 100 switch. Indirect connection is achieved by connecting the slave LightStream100 switch to another slave LightStream 100 switch that, in turn, is connected to a master LightStream 100 switch.
Performing the following steps for each slave LightStream 100 switch that will be either directly or indirectly connected to a master LightStream 100 switch:
Step 1 Provide protection against static electricity.
Step 2 Set the console terminal power switch to the OFF (O) position. Disconnect the EIA/TIA-232 cable connected to the console terminal from the switch's front panel.
Step 3 Set the power switch on the back of the main unit to the OFF (O) position. Unplug the power cable from the power outlet and then from the LightStream 100 switch.
Step 4 If present, disconnect all the optical cables and the EIA/TIA-232 cable from the front of the main unit. Mark the cables with their respective slot numbers to facilitate reconnection later.
Step 5 Remove the cover from switch. (Refer to the section "Removing the Cover" in the chapter "Installing the LightStream 100 ATM Switch" for detailed instructions.)
Step 6 Make sure that the jumper switch on any installed LINF card (P-8X79) is in the initial setting. If it is not in this setting, return the switch to the initial setting indicated in Figure 3-7.
Step 7 If this switch will be connected to a master LightStream 100 switch or another slave LightStream 100 switch that will, in turn, be connected to a master LightStream 100 switch, install an STS-3c/STM-1 LINF card into slot 0. (See Figure 4-1.) Placing the STS-3c/STM-1 LINF card in this slot allows the switch to receive data syncronization clocking signals. Make sure that the LINF card is securely fixed to the LINF stopper at the rear of the unit.
Step 8 If this switch will also be connected to another slave LightStream 100 switch as the clocking provider, install an STS-3c/STM-1 LINF card into any slot (except slot 0).
Step 9 Match the screw holes on the LINF card with the screw holes on the LightStream 100 units. Insert the screws and fasten them using the standard screwdriver.
Step 10 Remove the slot cover (without the window) from the slot where the LINF card is installed.
Step 11 Orient the slot cover so that it is right side up. Install the slot cover (with the window) from the inside of the cover and fasten it.
Step 12 Replace the LightStream 100 cover. (Refer to the section "Replacing the Cover" in the chapter "Installing the LightStream 100 ATM Switch" for detailed instructions.)
Step 13 Reconnect any optical cables removed earlier from the master LightStream 100 switch.
Connect the cables as follows:
Step 14 Connect one end of the optical cable to any slot on the master LightStream 100 switch. Connect the other end of the optical cable to slot 0 on the slave LightStream 100 switch.
Step 15 If you are connecting a slave LightStream 100 switch to another slave LightStream 100 switch that is, in turn, connected to a master LightStream 100 switch, perform this step. Connect one end of the optical cable to any slot on the slave LightStream 100 that is, in turn, connected to the master LightStream 100 switch. Connect the other end of the optical cable to slot 0 on the other slave LightStream 100.
Step 16 If you are connecting to another device, such as a router or terminal equipment, connect one end of the the optical cable to any slot on the master LightStream 100 switch. Connect the other end of the optical cable to the appropriate port on the other device.
Step 17 Reconnect the EIA/TIA-232 cable to the EIA/TIA-232 connector on the LightStream 100 front panel. Connect the other end to the console terminal. Make sure the communications parameters for the console terminal are set correctly. (Refer to the section "Setting Communications Software Parameters" in the chapter "Installing the LightStream 100 ATM Switch.")
Step 18 Reconnect the master and slave LightStream 100 power cables and the console terminal power cable to the power outlet.
For this procedure, the LightStream 100 switch is a slave switch. Perform the following procedure when connecting the LightStream 100 switch to another device designated as the master switch:
Step 1 Provide protection against static electricity.
Step 2 Set the console terminal power switch to the OFF position (O). Then disconnect the EIA/TIA-232 cable connected to the console terminal from the LightStream 100 front panel.
Step 3 Set the power switch on the back of LightStream 100 main unit to the OFF (O) position. Unplug the power cable from the power outlet and then from the LightStream 100 switch.
Step 4 If present, disconnect all optical cables and the EIA/TIA-232 cable by grasping the connector from the front of the LightStream 100 main unit. Mark the cables with their respective slot numbers to facilitate reconnection later.
Step 5 Remove the cover. (Refer to the section "Removing the Cover" in the chapter "Installing the LightStream 100 ATM Switch" for detailed instructions.)
Step 6 If this switch will be connected to a master device, install an STS-3c/STM-1 LINF card into slot 0. (See Figure 4-1.) Placing the STS-3c/STM-1 LINF card in this slot allows the switch to receive clocking signals. Make sure that the LINF card is securely fixed to the LINF stopper at the rear of the unit.
Step 7 If this switch will also be connected to another slave LightStream 100 switch as the clocking provider, install an STS-3c/STM-1 LINF card into any slot (except slot 0).
Step 8 Match the screw holes on the LINF card with the screw holes on the LightStream 100 units. Insert the screws and screw them in.
Step 9 Remove the front panel (without the window) from the slot where the LINF card is installed.
Step 10 Install the front panel (with the window) from the reverse side of the cover and fasten it. Ensure the front panel is right side up.
Step 11 Replace the cover. (Refer to the section "Replacing the Cover" in the chapter "Installing the LightStream 100 ATM Switch" for detailed information.)
Step 12 To set the configuration data, perform the procedures in the section "Setting System Configuration Data," earlier in this chapter.
Step 13 If present, reconnect the optical cables removed earlier from the LightStream 100 switch.
Step 14 Connect the optical cable in slot 0 of the LightStream 100 switch to the master device (router or terminal equipment). If other LightStream 100 units are connected, connect an optical cable from any slot (except 0) on a slave LightStream 100 switch to slot 0 of another slave LightStream 100 switch.
Step 15 Reconnect the EIA/TIA-232 cable to the EIA/TIA-232 connector on the LightStream 100 front panel. Connect the other end to the console terminal. Make sure the console terminal communications parameters are set correctly. (Refer to the section "Setting Communications Software Parameters" in the chapter "Installing the LightStream 100 ATM Switch.")
Step 16 Reconnect the LightStream 100 power cable and the console terminal power cable to the power outlet.
