Follow all warning notices provided with this product, as well as the safety procedures established by your company.
Follow all caution notices provided with this product, as well as the general equipment safety procedures established by your company.
Mechanical handling considerations
WARNINGRisk of personal injuryDue to the weight of the subrack, the mounting of the subrack in the rack requires two installers for safe working.
Take care when working near the top of the Station Interface Area that your hands do not scrape on the honeycomb screen.
CAUTIONRisk of damage to EMC meshThe EMC mesh on the subrack must not be placed onto an uneven surface or be placed on any protruding objects.
CAUTIONRisk of damage to equipmentWhen inserting a plug-in unit, ensure that the plug-in unit is inserted in the black card-guides and not the grey front panel locator guide to the right of the required position.

323-1061-200 Release 7 Standard
Electrical safety considerations
Optical safety
Note: The subrack should not be powered until after the installation is completed.
CAUTIONStatic sensitive devicesThe plug-in units contain static sensitive devices. These devices are sensitive to static electricity and must be protected by special handling and packaging. Refer to the static sensitive handling procedures in ÔDocumentation Overview and Safety, NTP 323-1061-090Õ.
Before removing the TN-1X subrack from the inner carton of the packaging, personnel must wear conductive bonded wrist straps conforming to BS CECC 00015 Part 1. The straps must be connected to an available earth point in the absence of an ESD bonding point on the equipment.
WARNINGPower to the subrackThe subrack should not be powered-up until the installation procedures are completed and the subrack is ready for commissioning. If the parent rack is already powered, the relevant rack fuses must be removed before the power connector is connected to the subrack.

Optical connector/Þbre handling
Nortel TN-1X Installation Procedures
The following precautions must be taken when working with single-Þbre optical cables:
¥ Safety glasses must be worn when installing optical Þbres.
¥ Small bits of glass Þbre are almost invisible. After handling single Þbre cables, hands should always be wiped clean or washed before making any contact with the eyes.
Handle optical Þbres carefully and always position them in a safe and secure location during installation.
¥ Do not handle pieces of cut Þbre with bare Þngers. Use tweezers, or the sticky side of a piece of vinyl tape, to pick up and discard any loose Þbre ends.
¥ All Þbre cuttings should be placed in a plastic bottle provided for that purpose.
end of chapter
CAUTIONOptical connectorsClean all optical connectors by an approved method before making any optical connection.
When making an optical connection, do not rotate the optical connector unnecessarily.
When not connected, Þt all optical plugs and couplings with captive caps.
CAUTIONDamage to optical ÞbresWhen dressing Þbres, take care not to exceed the minimum bend radius (typically 35 mm) and do not overtighten tyraps used for dressing as damage may result.
When connecting connectors, ensure that the optical Þbres are not trapped by the protective cover on the unit before sliding the unit in position.
WARNINGDanger from glass chipsIf there is any suspicion of a glass chip in the eye, seek medical attention at once.

Nortel TN-1X Installation Procedures
This chapter describes the procedures to be used when a Nortel TN-1X subrack is delivered to the customer as part of a supply-only contract.
Off-loadingThe consignment is the responsibility of the delivery vehicle driver until it has been off-loaded to the installation or storage area. Off-loading must therefore be supervised by the driver.
Only authorised lifting equipment and slings must be used unless a reciprocal agreement for use of the customerÕs equipment is in force and is valid.
Package handlingIdentify the top face of the container, identiÞable by packing labels, and keep the top face uppermost at all times.
The package contents are to be considered fragile at all times.
If packages are to be handled in wet weather conditions, adequate waterproof covering must be used to protect the package.
StorageIf the TN-1X equipment is to be stored before installation, the following storage conditions must be applied:
¥ Do not remove the equipment from its protective packaging.
¥ Store the equipment in an environment which is dry and controlled to prevent the formation of condensation.
¥ Whenever possible, store packages at a height which eases handling, i.e. between waist and shoulder height.
¥ Do not store the packages near sources of heat.
¥ Do not place heavy objects, e.g. wooden transit cases, on top of the package.

Receiving and unpacking
Unpacking
323-1061-200 Release 7 Standard
Tools requiredThe following tools are required to remove a TN-1X subrack from its primary and secondary packaging:
¥ Sharp pointed blade knife
¥ Conductive bonded wrist strap conforming to BS CECC 00015 Part 1
Packaging removalThe removal procedure is detailed in Figure 1-1.
Packaging disposalThe packaging may be disposed of as waste material. The customer may, however, Þnd it advantageous to retain the packaging which may then be used to return the equipment to Nortel should the need arise.
Checking contentsCheck the package contents against the Customer's Advice Note and ensure that the range of plug-in units Þtted to the supplied matches the TN-1X variant speciÞed on the order.
Figure 1-2 shows the layout of the plug-in units and interface modules of a typical equipped subrack.

Procedure 2-1Installing trafÞc cables to rack
Step Action Reference
ÑendÑ
1 Determine the routing of the traffic cables depending on the number of 2 Mbit/s and 34 Mbit/s tributary cables required and the cable entry (top or bottom) to the rack.
Table 2-8Table 2-9
2 For top cable entry, run the cables into the rack and leave at least 850 mm below the designated top fixing position of the subrack. This allows sufficient cable for dressing and termination.
3 For bottom cable entry, run the cable up the rack and leave at least 250 mm above the designated top fixing position of the subrack.
4 To assist in laying the cable in, Figure 2-4 illustrates the dressing layout after the cords have been terminated.

Installation of subrack into the rack
Nortel TN-1X Installation Procedures
Procedure 2-3 details the mounting of the TN-1X subrack into an NT ETSI rack, a 19" rack, or a BT 90/91 rack. The installation involves Þtting the subrack mounting brackets to the subrack and Þtting captive nuts to the parent rack. In the case of the ETSI rack, Þbre turning devices are also Þtted to the subrack and slide mounts may be used as a subrack mounting aid. For the BT racks, Þbre turning devices are Þtted, but slide mounts are not used.
The item numbers in Procedure 2-3 refer to Table 3-1 to Table 3-5 in Appendix A.
