Hardware Installation
This chapter provides procedures for installing a LightStream 2020 multiservice ATM switch
(LS2020 switch) in a networking environment. Installing an LS2020 switch involves several tasks in
two major categories:
1
Installing the LS2020 switch hardware
Separate sections in this chapter are devoted to the following topics:
— "Unpacking and Inspecting the LS2020 Switch Hardware"
— "Installing an LS2020 Switch in Rack"
— "Wiring a DC-Powered System"
— "Installing Fantails"
— "Attaching Data Cables"
— "Closing the Chassis"
— "Applying System Power"
Performing basic configuration procedures
2
The basic configuration tasks for the LS2020 switch are accomplished through configuration
scripts provided in this chapter.
Note
may not appear elsewhere in the LS2020 documentation set.
Unpacking and Inspecting the LS2020 Switch Hardware
When unpacking the LightStream 2020 switch, you should inspect the shipping container contents
to ensure the shipment is complete as well as check for damage that may have occurred during
shipment.
Step 1
Step 2
Step 3
Step 4
Refer to the LightStream 2020 Release Notes for important, release-specific information that
Check the shipping container before removing the LS2020 switch hardware from the
loading dock and inspect it for any signs of in-transit damage.
Transport the container to the systems area where the LS2020 switch is to be installed.
Cut the packing straps and lift the cardboard box off the LS2020 chassis. Remove the
packing material and bill of materials.
Check the bill of materials against the shipment received.

The exhaust is not located near the air intake of other equipment. Required Tools Ensure that you have the following items on hand before you begin installing the LS2020 switch: • A number 2 Phillips screwdriver for mounting the chassis. - Page 3 If your system is fully configured with function cards, you may also remove some or all of these cards to further reduce the weight of the chassis. (Refer to the LightStream 2020 Hardware Reference and Troubleshooting Guide for component removal instructions.) Put all removed electronic components in antistatic shielding bags or place them on antistatic mats.

This section applies only to systems with the DC power option. If you have a standard AC-powered system, skip to the section “Installing Fantails.” For general information on DC-powered LS2020 systems, see the LightStream 2020 Hardware Reference and Troubleshooting Guide. For power specifications, see the LightStream 2020 Site Planning and Cabling Guide. -
Page 7: Wiring Procedure
Ensure that the circuit breaker/power switch on each DC power tray is OFF. Step 2 Ensure that power to the circuit to which you will connect the LS2020 switch is OFF. Step 3 Connect the three system power wires to the LS2020 terminal block, using the slot-tipped screwdriver to secure the terminals. -
Page 8: Required Tools And Equipment
Fantails in the desired quantity (provided by Cisco Systems). • Required fantail cables (provided by Cisco Systems). • Fantail mounting screws, clip nuts, and washers (provided by Cisco Systems). If your equipment rack has metric-threaded rails, you must provide appropriate mounting screws. • A 5/16-inch slotted-tip screwdriver. - Page 9 For instructions on setting interface jumpers, see the LightStream 2020 Hardware Reference & Troubleshooting Guide. Select a position on the rack to mount the fantail. Attach the four clip nuts provided with Step 1 the fantail to the appropriate holes in the rails.

Page 10: Connecting Cables
If you are mounting an X.21 fantail, set the DTE/DCE switches for each port to the desired Note mode. (See the LightStream 2020 Hardware Reference and Troubleshooting Guide for more detailed instructions on configuring X.21 ports as DTEs or DCEs.) If you select a DCE interface, note that you must install a gender converter on each DTE port in order to change the female connector to a male connector. -

flow of cooling air through the chassis. Applying System Power You can power your LS2020 switch with either an AC or a DC power tray. In addition, you can equip your LS2020 switch with an optional (redundant) power tray of like type (see Figure 2-5). - Page 12 “Installing Modems.” If a yellow fault (FLT) LED stays lit on any card, indicating the existence of a problem, do either of the following: • Refer to the LightStream 2020 Hardware Reference & Troubleshooting Guide to determine why the FLT LED indication occurred and how to correct it. •...

Page 14: Required Configuration Information
Note If you experience a problem while performing basic configuration tasks, you may need to shut down and restart the system. Refer to the LightStream 2020 Hardware Reference & Troubleshooting Guide for instructions on performing an orderly shutdown. Required Configuration Information You need to have the following information available before beginning the basic configuration... - Page 15 Host Name You must assign a unique host name to each LS2020 node. Typically, a name can be chosen to reflect the node’s geographic location (for example, Tokyo2) or its function within an organization (for example, mfg3). The name may consist of any combination of letters and numbers up to 32 characters, but it must not begin with a number.

NP access cards remain unaffected in the current release, that is, these ports always pass IP traffic to the NP. For detailed information about configuring Ethernet port attributes, see the LightStream 2020 Configuration Guide. For detailed information about IP addresses, subnet masks, and network classes, see the LightStream 2020 Site Planning and Cabling Guide. -

- Page 21 For baud rate selection, this step requires that your LS2020 be equipped with a modem Step 7 attached to the same switch as the terminal and that you have the ability to dial in to the LS2020 chassis. If you can dial in to the LS2020 chassis, do so and continue with Step 8.
- Page 22 However, one difference to note is that the setsnmpconfig command checks for the presence of configuration files. (Normally, these files are not present during a typical installation of a new LS2020 switch.) If the system finds such files, it asks if you want to continue, as shown below: Configuration information already exists.
- Page 23 If you answer y (yes) to this query, the system overwrites the existing configuration files Caution for this particular LS2020 node, effectively deleting the files. If configuration files are present and you choose not to overwrite them, the setsnmpconfig script cannot continue.

If your LS2020 switch contains two NPs, ensure that their respective clocks agree to within Note 1 minute. If the clocks differ by more than 1 minute, the software that synchronizes files between the two NPs may not operate properly.
