NOTE To prevent ESD events when handling this equipment, all personnel should utilize ESD shoes or wrist straps, or an ESD flooring must be present. Compliance Codes This product is intended to be installed in products providing a Type “B” or “E” enclosure, and in a Restricted Access Location. See Table 1. Table 1.

1. Flush-mount: For flush-mount systems, the Total Access 1500 shelf must be mounted from the rear of the rack, with mounting bracket flanges facing rearward. 2. Mid-mount: For mid-mount systems, the Total Access 1500 shelf must be mounted from the front of the rack, with the mounting bracket flanges facing forward. NOTE Other orientations will require either mounting from the front or rear, and depend on the rack type installed in the CO and the standard operating procedures established by your CO.

The power bus and frame ground route to all the cards in the shelf. The number of shelves that can be placed in a 7-foot central office rack depends on the type of service deployed and the number of access modules in the shelf. After connecting and checking the ground to the Total Access 1500 shelf, connect power to the shelf. Check to make sure your power source is providing the correct power and polarity to the shelf. To connect power to the shelf: 1.

Up to 14 dual LIU systems or 28 single LIU systems may be daisy chained to a single output from the timing source, so only one wire run is required from the timing source for an installation of up to 14 or 28 Total Access 1500 shelves. Use wire of the same type as was used for the wire run from the CO clock source to the Total Access 1500 shelf. The following steps provide instructions for connecting up to 14 or 28 Total Access 1500 shelves to a single external timing source. 1.

Connecting Alarm Outputs Depending on the vendor equipment employed at the CO, wiring external alarms from the Total Access 1500 shelf will vary slightly. The important consideration is whether the external alarm equipment requires a Normally Open (NO) or Normally Closed (NC) circuit to pass an alarm. After determining what the CO equipment requires, connection can be made to the equipment from the Total Access 1500 shelf, see Figure 5 for location of alarm contacts.
PAGE 10
Network Management Connections The Total Access 1500 shelf integrates onto the backplane several different management ports to allow for remote management of the shelf. The management interface is on the System Controller Unit (SCU) discussed in detail in the System Description section of the Total Access 1500 System Manual. Up to 16 shelves can be linked together on the RS-485 bus for management of those shelves from a single management interface.
