Parts Checklist

Before proceeding with the installation, go through this parts checklist and verify that all ordered parts are present and in good condition. If anything is missing or damaged, report it to a StrataCom Order Administration representative.

Check the cabinet for the following inventory:

Make sure all purchased cards are present. Check the number and type of cards shipped against the number and type of card purchased.

Correct number of ARIs

Note Several of the IGX 16/32 front cards can run in the IGX 8. This requires no modifications or re-configuration. The cards are the FRM, NTM, and CVM series cards.

An inventory list of the installed cards is shipped with the unit. The list includes each card’s serial number, revision number, and slot number (serial and revision numbers are also found on the solder side of each card). After verifying that the correct cards are present, tape a copy of the inventory list to the back of this manual.

Site Preparation

The IGX 8 site must satisfy the following requirements:

  • Space

The standalone IGX 8 requires a floor area 19.9 inches (50.5 cm) wide and 60 inches (180 cm.) deep. This depth allows for opening the front door. Sufficient clearance around the cabinet must also be provided for access to the front and back of the cabinet while the door is open. The rack-mount IGX 8 requires 24.44 inches of vertical space. In a rack-mount system, the mounting rail pattern follows an EIA standard of 56 inches or 32 rack-mount units.

  • Environment

The IGX operating environment should be as follows: Temperature and humidity range: 0 to 40 C (32 to 104 F). Up to 85% relative humidity, non-condensing. Shock: withstands 10 G, 10 ms. at 1/2 sine wave. Vibration: Withstands 1/4 G, 20 to 500 Hz.

  • Power

For AC power use, an AC power source must be available within 6 feet (1.8 m) of the IGX. For systems using a DC source, StrataCom does not supply the DC power cord, so the user or installer determines the cord length and the distance between the IGX and DC source. The appropriate wire is 10 to 12 AWG or 4 sq. mm.

  • Heat Dissipation

A fully loaded IGX 8 dissipates approximately 3,500 BTUs (1 KW hour) when AC powered and a maximum of 2720 BTUs when DC-powered.

  • Weight

A fully loaded IGX 8 with four AC power supplies can weigh up to 173 lbs (79 kgs). Note When moving a STRATM cabinet, do not push it at its sides. Push at the front or back. See «System Installation» section.

  • Flooring

Raised flooring with sufficient under-floor space to house the cables is recommended.

  • Mounting

The IGX 8 is either mounted in a rack or free-standing (in a stand-alone cabinet). The location of the IGX should accommodate the routing of the data cables and the termination of the telephone company’s or common carrier’s circuits.

  • Electrostatic Discharge

The IGX 8 has one mounted wrist strap at the front and one at the back of the cabinet. Personnel with access to the IGX 8 cards should put on a wrist strap before handling the cards.

Seismic Considerations

The only available anchoring for an IGX 8 is in a rack that can be anchored to the floor (or ceiling). In a STRATM cabinet, provisions are available for seismic anchoring. Holes exist in the upper and lower corners for 3/8″ or 1/2″ bolts. Also, an optional stability plate can be purchased with the STRATM cabinet. The stability plate is bolted to the floor, then the STRATM cabinet is bolted to the stability plate. The «STRATM Seismic Anchoring » section contains instructions for installing the seismic stability plate.

Safety Requirements

The following paragraphs contain general safety information and information on T1 and CEPT (E1) safety requirements.

General Requirements

The following safety requirements must be observed:

  • It is vitally important that connector pins correctly align with connectors. Before inserting a card, make sure the pins are straight and the connectors on the card and the backplane align with each other. Insert the card gently.

  • Only authorized personnel should have access to the IGX 8.
  • For the IGX 8 and peripheral equipment to function safely and correctly, use only the power cords, cables, and connectors that are specified for the equipment, and make sure they are in good condition.
  • Use the wrist strap at the front or the back of the IGX 8 cabinet when handling cards.

    Power and Grounding

    Installation

    This section lists the requirements that relate to electrical power and grounding. These requirements cover installations at Central Office (CO) and Private Enterprise locations.

    Electrical Power for AC Units

    An AC power source must be available within 6 feet (1.8 m) of the system and easily accessible. Before turning on the power, verify that the power supplied to the node comes from a dedicated branch circuit.

    The receptacles into which the IGX plugs must be of the grounding type. The grounding conductors that connect to the receptacles should connect to protective earth at the service equipment.

    Electrical Power for DC Units

    Only a -48 VDC supply that complies with the Safety Extra Low Voltage (SELV) requirements of EN 60950 can connect to the IGX DC input.

    For DC supply connections, consult local and/or national codes for proper conductor sizing. The conductors must be suitable for 20 Amps. Wiring that is 10 to 12 AWG (4 sq. mm) is adequate.

    Bonding and Grounding

    To maintain the full EMI and EMC integrity of this equipment, it must be bonded to an Integrated Ground Plane or an Isolated Ground Plane network. The purpose of this is to mitigate the damaging effects to equipment from Electrostatic Discharge and Lightning. Refer to the latest edition of ITU Recommendation K.27 or Bellcore GR-1089-CORE requirements to ensure that the correct Bonding and Grounding procedures are followed. As recommended in these documents, a frame bonding connection is provided on the StrataCom STRATM cabinet for rack-mounted systems and on the stand-alone cabinets.

    Refer to «Making the Frame Bonding (Ground) Connection » later in this chapter for information on the locations of the frame bonding connections and how to make a connection.

    Except for the AC power supply module, every module in a rack-mount system relies on the rack itself for grounding. Therefore, the rack must be properly connected to protective earth before operating the system.

    A DC powered IGX system must have grounding conductors connected at two separate locations, as follows:

    • The grounding conductor provided with the supply source must be connected to the appropriate terminal of the PEM. «DC Power Connections » section, later in this chapter, describes how to make this connection.

  • A grounding conductor as described in paragraph 1 of this section must connect to the appropriate terminal of a rack assembly or to the chassis of an IGX 8.

    CEPT Requirements

    These requirements may be relevant to a private network connected to the public switched networks in some international service areas.

    • The following port types on the IGX are approved to carry public-switched, non-voice traffic (OTR001, issue 3, port types 2DN):

    • BC-E1 ports (G.703 2048 Kbits per second).

  • SDI-RS-232, LDI-RS-232, BC-SR, SDI-RS-449, FRI-V.35 (approved for direct connection to V.35 leased digital circuit).
  • SDI-RS-449 (when connected via StrataCom RS449/X.21 interface cable).
  • The following port type on the IGX is approved to carry PSTN voice traffic:

    • BC-E1 ports (G.703 2048 Kbps, when connected to a CVM8 or NTM8 front card).

  • Note Cables must be attached so that their removal requires a tool.

    STRATM Seismic Anchoring

    This section describes installing the STRATM cabinet with the optional stability plate for seismic anchoring. If the stability plate is not present, go to the next section. To set up the STRATM cabinet with the stability plate:

    Step 1 Use the dimensions in Figure 1-3 to drill the holes for installing the stability plate.

    Step 2 Remove the stability plate from the base of the STRATM cabinet. Save these nuts and bolts.

    Step 5 Using the nuts and bolts from the shipping setup, secure the STRATM cabinet to the stability plate.

    Figure 1-1: Stability Plate Dimensions

    Figure 1-2: STRATM Installation Over Stability Plate

    IGX 8 Installation

    Installing an IGX 8 requires the following tools and equipment:

    • Box knife (or equivalent)

  • Flat blade screwdriver set
  • Phillips screwdriver set, which must include a No. 1 size for front card installation
  • Grounding wrist strap
  • A variety of wrenches, possibly including an adjustable wrench or channel locks, for raising and lowering cabinet feet (for example, a STRATM cabinet requires a 1 3/8″ wrench)
  • 5/32″ Allen wrench for opening the IGX 8 door (comes with the unit)

    Stand-Alone System Installation

    The installation steps consist of placing the stand-alone IGX 8 at its operational location, unpacking it, and verifying the structural and power connection integrity. Note that a stand-alone cabinet is 19.9″ wide.

    After the system resides at its operational location, follow the steps for connecting power. If the system has an AC power source, go to «AC Power Connections » section. If the system has a DC power source, go to «DC Power Connections » section.

    Rack-Mount Installation

    The rack-mount IGX 8 fits in a 19 inch (48.25 cm.) rack with a minimum of 17.75 inches between rails. For mounting the chassis in a rack, brackets are attached to the front of the chassis. A pair of mounting brackets are attached at the back of the chassis after it is placed in the rack. Brackets for a mid-rack mounting also come with the kit.

    Because of the weight of the IGX 8, StrataCom includes two temporary spacer brackets and a temporary mounting bracket to help with the installation. These pieces are removed after installation. The temporary spacer brackets stabilizes the rack, and the temporary mounting bracket together with the spacer brackets creates a partial shelf onto which the installers can slide the node. These pieces support the system while installers secure the permanent front and back mounting brackets to the rack.
