Site Preparation

This chapter describes the safety and site preparation issues that you should be familiar with before you attempt to physically install your IE2100 Series system.

Warnings

You should observe the following safety guidelines when working with any equipment that connects to electrical power or telephone wiring. They can help you avoid injuring yourself and damaging the IE2100 Series.

Warning Read the installation instructions before you connect the system to its power source.

Warning The safety cover is an integral part of the product. Do not operate the unit without the safety cover installed. Operating the unit without the cover in place will invalidate the safety approvals and pose a risk of fire and electrical hazards.

Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Make sure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. and 240 VAC, 10A international are used on the phase conductors (all current-carrying conductors).

Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

Warning Ultimate disposal of this product should be handled according to all national laws and regulations.

Warning Before working on a system that has an On/Off switch, turn OFF the power and unplug the power cord.

Warning Read the installation instructions before you connect the system to its power source.

Warning The device is designed to work with TN power systems.

Warning The ports labeled "10BaseT", "100BaseTX", and "10/100" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Avoid connecting these circuits to telephone network voltage (TNV) circuits.

Warning There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions.

Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.

Working with Electricity

Follow these guidelines when working on electrical equipment:

• Locate the emergency power-off switch for the room in which you are working. If an electrical accident occurs, you can act quickly to turn off the system.

• Disconnect all power by powering off the system and unplugging the power cord before:

  • Installing or removing a chassis

  • Working near power supplies

• Do not work alone if potentially hazardous conditions exist.

• Never assume that power is disconnected from a circuit; always check the circuit.

• Look carefully for possible hazards in your work area, such as moist floors, underground power extension cables, frayed power cords, and missing safety grounds

• If an electrical accident occurs:

  • Use caution: do not become a victim yourself.

  • Power off the system.

  • If possible, send another person to get medical aid. Otherwise, assess the victim's condition, then call for help.

  • Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

• Disconnect all power and external cables before installing or removing a chassis.

• Never install equipment that appears damaged.

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

• Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

• Always use caution when installing or modifying telephone lines.

• Never perform any action that creates a potential hazard to people or makes the equipment unsafe.

Preventing Damage from Electrostatic Discharge

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs when electronic components are handled improperly and can result in complete or intermittent failures.

• Always follow ESD-prevention procedures when removing and replacing components. Verify that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, making sure that it makes good skin contact. Connect the grounding clip to an unpainted surface of the chassis frame to safely ground ESD voltages. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.

• Periodically check the resistance value of the antistatic strap, which should be between 1 and 10 Mohms.

Preventing EMI

When you run wires for any significant distance in an electromagnetic field, electromagnetic interference (EMI) can occur between the field and the signals on the wires.

Note that:

• Bad plant wiring can result in radio frequency interference (RFI).

• Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the system, and can even create an electrical hazard by conducting power surges through lines and into the system.

To predict and remedy strong EMI, consult RFI experts.

Covering Empty Slots

Ensure that all cards, faceplates, and covers are in place. Blank faceplates and cover panels are used to:

• Prevent exposure to voltages and currents inside the chassis.

• Help contain electromagnetic interference (EMI) that might disrupt other equipment.

• Direct the flow of cooling air through the chassis.

Preparing Your Site for Installation

Make sure your site is prepared properly before beginning installation.

Environmental

When planning your site layout and equipment locations, keep in mind the precautions described in this section to help avoid equipment failures and reduce the possibility of environmentally caused shutdowns. If you are currently experiencing shutdowns or unusually high errors with your existing equipment, these precautions will help you isolate the cause of failures and prevent future problems.

Use the following precautions when planning the operating environment for your IE2100 Series system:

• Always follow the ESD-prevention procedures described in the section "Preventing Damage from Electrostatic Discharge" to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.

• Make sure the chassis cover is secure. The chassis is designed to allow cooling air to flow effectively within it. An open chassis allows air leaks, which could interrupt and redirect the flow of cooling air from internal components.

• Electrical equipment generates hear. Ambient air temperature might not be adequate to cool equipment to acceptable operating temperatures without adequate circulation. Make sure that the room in which you operate has adequate air circulation.

Choosing a Site For Installation

Warning This unit is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock and key, or other means of security, and is controlled by the authority responsible for the location.

• Choose a site with a dry, clean, well-ventilated and air-conditioned area.

• Choose a site that maintains an ambient temperature of 50 to 95 degrees F (10 to 35 degrees C).

Grounding the System

Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

Creating a Safe Environment

Follow these guidelines to create a safe operating environment:

• Keep tools and chassis components off the floor and away from foot traffic.

• Clear the area of possible hazards, such as moist floors, ungrounded power extension cables, and missing safety grounds.

• Keep the area around the chassis free from dust and foreign conductive material (such as metal flakes from nearby construction activity).

AC Power

• The system is designed for connection to TN power systems. A TN power system is a power distribution system with one point connected directly to earth (ground). The exposed conductive parts of the installation are connected to that point by protective earth conductors.

• Ensure that the plug-socket combination is accessible at all times, because it serves as the main disconnecting device.

The IE2100 Series system has the following power requirements:

• Universal input: 100-120/200-240 VAC

• Frequency: 50-60HZ

• Maximum power: 65 watts

Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Make sure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. and 240 VAC, 10A international are used on the phase conductors (all current-carrying conductors).

Warning The device is designed to work with TN power systems.

Cabling

This section details the pinout information for these cables, so that you can purchase the correct cable for your network connection, and replace the console cable and adapters if that becomes necessary.

A structured wiring system provides a standardized way to wire a building for all types of networks for the IE2100 Series appliance to be installed. The main distribution frame links all the building's interior wiring and provides an interface connection to circuits coming from outside sources such as the local telephone company. Wiring hubs (peripherals for cabling installations) provide the connection logic unique to Fast Ethernet cables that the IE2100 Series uses. Unshielded twisted pair (UTP) copper wire is used to connect the IE2100 Series and distributes the network connections to wall jacks near each piece of network equipment.

Warning The ports labeled "10BaseT", "100BaseTX", and "10/100" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Avoid connecting these circuits to telephone network voltage (TNV) circuits.

Ethernet Standards

To connect the IE2100 Series to your network, you must use one of the following Fast Ethernet cables:

• An RJ-45 to RJ-45 straight-through cable to connect the IE2100 Series to a hub

• An RJ-45 to RJ-45 crossover cable to connect the IE2100 Series to another device

The Ethernet configuration using unshielded twisted pair (UTP) wire is known as 10BaseT because it uses 10 megabits per second (Mbps) signaling speed, direct current, or baseband, signaling, and twisted pair wire.This configuration includes a central wiring hub with special circuitry to isolate malfunctioning segments of the network. UTP wire uses an RJ-45 connector at each end of the wire. New signaling schemes such as 100BaseT and gigabit Ethernet use the same UTP cabling with upgraded hubs and adapters.

Use a CAT 5 UTP cable at minimum to connect to a 100BaseT network. Use a CAT 3 UTP cable at minimum to connect to a 10BaseT network.

Table 1-1 lists the pinouts for a straight-through 100BaseT cable.

Table 1-2 lists the pinouts for a crossover 100BaseT cable.

Console Cable and Adapter

The EIA/TIA-232 console port on the IE2100 Series is configured as data terminal equipment (DTE) and uses an RJ-45 connector. A console cable kit is provided with your IE2100 Series to connect an ASCII terminal or a PC running terminal emulation software to the console port. The kit contains an RJ-45 to RJ-45 rollover cable and one RJ-45 to DB-9 female DTE adapters.

Table 1-3 lists the pinouts for this configuration.

Rollover Cable

You can identify a rollover cable by comparing the two modular ends of the cable (Figure 1-1). Holding the cables in your hand, side-by-side, with the tab at the back, the wire connected to the pin on the outside of the left connector (pin 1) should be the same color as the pin on the outside of the right connector (pin 8).
