Site Preparation

Site Prep Checklist · Space Requirements · Electrical Requirements · Environmental Requirements · Unpacking and Inspecting the Hardware

This chapter tells you how to prepare your site for the installation of LightStream 2020 enterprise ATM switches. It includes information on the system's weight, dimensions, environmental and electrical requirements, and a site planning checklist.

LightStream switches can be installed in any area that meets the specifications outlined in this chapter. A dedicated computer room with raised floors, controlled temperature and humidity, and clean air is desirable, but is not required.


Site Prep Checklist

Use this checklist several weeks before the expected delivery date to ensure that your site is ready to receive LightStream hardware.

  1. Ensure that the area you select to house your LightStream system allows enough space for front and rear access to the LightStream chassis, as shown in Figure 2-1.

  2. We recommend that you develop a plan for managing external data cables. (This might involve running the cables under a raised floor, or through a dropped ceiling, or placing the system in a low-traffic area where cables won't be disturbed.)

  3. Ensure that the floor is strong enough to support the system. See the subsection entitled Weight for LightStream weights, and add the weights of the rack and cables.

  4. Calculate the heat dissipation of your LightStream system using the information in Table 2-6. Taking into account the heat generated by the LightStream switch and any other equipment installed in the same room, ensure that your HVAC system can maintain the temperature and humidity ranges outlined in Table 2-9.

  5. Ensure that each LightStream system has its own dedicated branch power circuit with circuit breaker and a grounded outlet. If you're installing a DC-powered LightStream system, you may wish to arrange to have an electrician present at installation time. An electrician or other qualified person must wire the chassis to a DC power source.

  6. If several LightStream switches will be installed at your site, develop a method for telling them apart. We recommend that you assign a unique name or number to each system and label each chassis clearly.

  7. Obtain an equipment rack for the LightStream system. (See Chapter 3 for rack guidelines.)

  8. To provide connectivity to each node in the case of network problems, consider obtaining modems for each switch card in your LightStream network. (Each switch chassis can have one or two switch cards.) Modems must be Hayes-compatible and able to operate at 2400 baud.

  9. Ensure that a Sun workstation is available to manage your LightStream network, and that the workstation meets all the hardware and software requirements listed in Chapter 4.

  10. Obtain IP addresses for each switch in your LightStream network. (See the LightStream 2020 Installation and Troubleshooting Manual for more information on IP addresses.)

  11. Order data cables. (See Chapter 5 for information about I/O connectors and selected cables.)

  12. Order the appropriate country power kit or DC mounting kit. (See Chapter 5 for information about the power cords included in kits.)


Space Requirements

Keep the following considerations in mind when choosing a location for your LightStream hardware:

Electrical Requirements

Each LightStream chassis requires a dedicated branch circuit. See Table 2-3, Table 2-4, and Table 2-5, which specify the power requirements and power ratings of LightStream systems.

The following notice applies to each LightStream switch:

The LightStream switch is designed to operate with all boards, bulkheads, filler panels, covers, and components (disks and blowers) in place and firmly screwed to the chassis frame. When all these items are in place, they form an enclosure that performs three important functions:

Caution Do not operate a LightStream switch without all boards, bulkheads, filler panels, covers, and components in place and firmly screwed to the chassis frame. You must operate the LightStream switch properly to limit access to hazardous voltages and currents, to contain EMI within the chassis, and to maintain the flow of cooling air through the chassis.

Environmental Requirements

The physical environment during operation, storage, and transport of the LightStream switch must meet the specifications outlined in Table 2-9.

Table 2-9 : Environmental Specifications

Operating temperature at sea level (760 mm Hg)1 41° to 104° F (5° to 40° C)
Relative operating humidity 10% to 90% noncondensing
Altitude1 Up to 10,000 ft (3048 m)
Nonoperating temperature -4° to 140° F (-20° to 60° C)
Nonoperating humidity 10% to 95% noncondensing
Air quality The LightStream switch is designed to run in a non- corrosive, relatively dust-free environment. The enclosure does not contain air filters; a relatively dust-free environment prevents accumulation of dust on the circuit boards and in the air flow inlet, internal flow paths, and exhaust openings.
Noise Emission 68 db(A) maximum

1 Reduce the maximum operating temperature by 15° F (.565 °C) for every 1000 ft (304.8 m) above 10,000 ft (3048 m) altitude.


Cooling Air and Hardware Placement

A LightStream chassis takes in cooling air through the bottom of the front panel and exhausts it at the top rear and the top right side. (The air vents on the right side can safely be covered with rack side panels, but should not be otherwise blocked.) To minimize thermal problems, position the chassis such that

  • the LightStream switch's air intake panel is not near the exhaust of other equipment

  • the LightStream switch's exhaust is not near the air intake of other equipment


Unpacking and Inspecting the Hardware

When it arrives, unpack the LightStream switch as follows:

  1. Before moving the shipping container from your loading dock, inspect it for any signs of in-transit damage.

  2. Transfer the container to the systems area.

  3. Cut the straps and lift the cardboard box off the chassis. Remove the packing material.

  4. Inspect all external surfaces for signs of damage. Pay special attention to any areas where you noticed damage to the shipping container.

  5. Document any damage noted during the inspections and notify your LightStream vendor.

  6. See the LightStream 2020 Installation and Troubleshooting Manual for instructions on installing the switch.
Caution Do not use the handles on the disk assemblies to lift the chassis. These handles are not designed to support the system's weight and will break off under stress.
Selecting a Rack

Selecting a Rack

Rack Characteristics · Rack Space: Height and Depth

This chapter provides guidelines on selecting an equipment rack for your LightStream 2020 enterprise ATM switch.


Rack Characteristics

The rack you use for your LightStream switch should be a TIA or EIA standard 19-inch (48.3 cm) wide rack that meets the specifications outlined below.

  • Rails with RETMA hole pattern. (Mounting screws, clip nuts, and dress washers are shipped with each LightStream system. If your rack has metric-threaded rails, you must provide your own metric screws.)

  • Leveling feet

  • Perforated top

  • Open bottom

  • Solid side panels

  • Front and rear doors are optional; if present, they must be fully louvered

Note For physical stability, when a LightStream chassis is installed in a rack, the combination should comply with UL Standard 1950, Par. 4.1.1, and IEC 950, 4.1.1.


Rack Space: Height and Depth


Chassis

A LightStream chassis needs 26.25 in. (15 rack units, or 66.7 cm) of vertical rack space.


Cables and Fantails

A LightStream rack should be at least 30 in. (76.2 cm) deep; 36 in. (91.4 cm) is recommended so there is comfortable clearance at the rear for fantails and cables.

If your system contains low-speed line cards, consider the system's fantails when you plan rack space. One LightStream switch using V.35 and/or RS-449 fantails can have up to 18 fantails---two per low-speed line card. (A system using only X.21 fantails can have a maximum of nine fantails---one per low-speed line card.) Each fantail is 1.75 inches (1 rack unit, or 4.45 cm) high; thus a switch fully loaded with fantails uses up to 31.5 inches (80 cm) of fantail space at the rear. (Medium-speed, packet, and cell line cards do not use fantails.)

Network Management Station Requirements

Network Management Station Requirements

Hardware Requirements · Software Requirements

To manage a network of LightStream" 2020 enterprise ATM switches, you need a workstation that meets the hardware and software requirements listed in this chapter.


Hardware Requirements

The network management system (NMS) workstation must be a Sun SPARCstation (Sun-4). Although LightStream management software is designed to run on any SPARCstation model that runs SunOS 4.1.x and HP OpenView, only the following models are supported and tested:

  • SPARCstation 10

  • SPARCstation 20

  • SPARCstation 2

  • SPARCstation IPX

  • SPARCstation IPC

The NMS workstation must have:

  • At least 32 MB of memory

Note 24 MB of memory may be sufficient if you choose not to run HP OpenView, or if you have a small network (fewer than eight LightStream nodes).

  • At least 32 MB of swap space, if you choose not to run HP OpenView. If you do run HP OpenView, you'll need to configure a minimum of about 90 MB of swap; consult HP OpenView documentation for more precise information.

  • A hard disk drive. LightStream recommends a hard disk of at least 500 MB for a stand-alone workstation that will not run HP OpenView, or a hard disk of at least 1 gigabyte for a stand-alone workstation that will run HP Openview. If you plan to load any software other than that described in the Software Requirements section below, you may need to increase the size of your hard disk.

  • At least 50 MB of free disk space to load LightStream's management software

Note You will need additional disk space to load Motif, X Windows, HP OpenView, and any other software you choose to install on the NMS.

  • An Ethernet port

  • A quarter-inch tape drive for installation of LightStream software

  • A color monitor to run LightStream's monitor software


Software Requirements

The NMS workstation must have the following software loaded:

  • SunOS 4.1.x/Solaris 1.1.x

Note The operating system version required for LightStream network management is not the default OS currently shipped with new Suns; you must ask for this OS specifically.

  • X Window System X11R5

  • Motif 1.2, or a compatible window manager such as the twm included with X11R5

In addition, you may choose to run HP OpenView version 3.3 network management software on your NMS workstation. For information on HP OpenView's requirements, see the HP OpenView Management Platform Performance and Configuration Guide, available from Hewlett-Packard. Cables and Connectors

Each FDDI port consists of two connectors, A (red) and B (blue). FDDI connectors are keyed to ensure proper connection of the cable to the access card.


FDDI Cable

Where used: To connect a LightStream switch's multimode FDDI access card to another FDDI device. LightStream Corp. does not provide this cable; it is widely available from other sources.

LightStream's FDDI interface operates at a wavelength of 1300 nanometers. Cables should conform to the following specifications:

  • Cabling: 62.5 micron core, graded-index fiber with an optical loss of 11 db and a maximum cable attenuation of 1.5 db/km at 1300 nanometers.

  • Connectors: MIC

  • Maximum path length (all cables in a connection, end to end): 2 km

Note Protective covers are provided for all FDDI access card and cable connectors. To shield connectors from dust and damage, put covers on any connectors that are not in use.

Ethernet 10Base-T Straight-Through Cable

Where used:

  • To connect an Ethernet access card on a LightStream switch to an Ethernet hub.

  • To connect an Ethernet access card on a LightStream switch directly to another device on the Ethernet, such as a workstation, when the workstation port has a built-in crossover function. (See the note under Ethernet 10Base-T Crossover Cable.)

LightStream Corp. does not provide this cable; it is widely available from other sources. See Figure 5-21.

Ethernet 10Base-T Crossover Cable

Where used: To connect an Ethernet access card on a LightStream switch directly to another device on the Ethernet, such as a workstation.

Note Some MAUs (medium access units) have a built-in crossover function, and therefore use straight-through cables instead of crossover cables. Ports on such MAUs are marked with the letter X.

LightStream Corp. does not provide this cable; it is widely available from other sources. See Figure 5-22.

Country Kits and Power Cordsets


Introduction

Several power cordsets are available for AC-powered LightStream ATM switches, both with systems and as spare parts. This section can help you choose the right cordset for your site.

Note The information in this section does not apply to DC-powered LightStream systems. A DC-powered system must be permanently wired to a DC power source; it does not use a detachable power cord. In place of a Country Power Kit, each DC-powered system is shipped with a DC Mounting Kit, order number 0104-48.

If you are specifying a cordset as part of a new system order, refer to the LightStream Price List or Product Catalogue and order the appropriate Country Power Kit. This ensures that you will also receive the appropriate labels and instructions for the country of destination.

If you want to check the cordset included in a specific Country Power Kit, use TableTable 5-1, which cross-references cordset product numbers and Country Power Kit models.

If you need to order a replacement cordset that is not part of a Country Power Kit, you must use the cordset's part number. (The part number (P/N) of each cordset appears above the cordset illustration, later in this section.)


LightStream Power Cordsets

An AC-powered LightStream chassis is equipped with a recessed male power inlet. The chassis connector follows IEC standard 320 C20 and requires a cordset with an IEC 320 C19 female connector. (All the cordsets offered for the LightStream switch have IEC 320 C19 female connectors.)

Table 5-1 summarizes the information in this section; it lists the countries of use, cordset rating, plug type, part number, and Country Power Kit for each cordset. Figure 5-26 through 5-26 illustrate the cordsets.
