GENERALThis practice is used in association with the NIU3circuit card practice, P/N 61213075L2-5.The ADTRANÆ NIU3 3-Slot Shelf (P/N 1212073L1)installs in a standard 19-inch bay (23-inch mountingflanges also included) at a designated location conve-nient to the customer.Revision HistoryIssue 4 of this document provides the inclusion of acautionary statement concerning the bypass relays inthe Installation section on page 2.2. DESCRIPTIONThe NIU3 3-Slot Shelf is an all-metal constructionhousing that has slots for 3 NIU3 horizontally-mountedcircuit cards. Card guides direct the card to thebackplane edge connector. When properly inserted,thumbscrews on the NIU3 front panel align and fastento threaded holes on the shelf. Shelf slots are numbered1 through 3, left to right, looking at the front of the shelf.The backplane circuitry is protected by a metal coverthat has openings for BNC data jacks, pass-throughrelays, power terminal connections, and alarm pins.Removable covers provide security for power and alarmconnections, and pass-through and alarm relays. Allconnections are clearly labeled.FeaturesThe NIU3 3-Slot Shelf provides the following featuresand functions.ï Field replaceable pass-through relays ensure virtu-ally uninterrupted transmission during card replace-ment, failure, or power loss.ï BNC transmit/receive jacks provided for eachNIU3 card.ï Shelf alarm relay terminals provide alarm indica-tion.ï Dual −48 VDC or ±24 VDC power feeds provided.ï Sturdy metal construction with durable powder-coated enamel finish.ï Mounting and accessory hardware included.ComplianceThe NIU3 3-Slot Shelf is intended for installation in arestricted access, environmentally controlled, orprotected location only.See Table 1 for compliance codes.
