Description

GNP Computers RJ21/RJ45 Entry Panel 1-503582 Rev A 4-Port RJ45 Telco PCB

This is a telecom entry panel PCB that converts RJ21 (Telco 50-pin) connections to four RJ45 trunk ports. It was used in telecommunications and data center switching equipment to interface between legacy telco backplanes and modern Ethernet cabling.

Specifications & What's Included

  • Model: 1-503582 Rev A (Secondary: GNPO1990375C)
  • Rear connector: RJ21 (Telco 50-pin)
  • Front connectors: 4x RJ45 trunk ports (Trunk 0/2, 1/3, 4/6, 5/7)
  • Form factor: PCB / Card Module
  • Manufactured in United States
  • PCB only; no cables or mounting hardware included

Applications

This type of entry panel was standard in telecommunications switching systems, PBX equipment, and early carrier-grade networking infrastructure. It supported trunk line interfacing and was commonly used in Lucent, Nortel, and similar telco systems. The card bridges legacy 50-pin telco distribution with standard RJ45 cabling.

Condition: Used
This GNP Computers RJ21/RJ45 Entry Panel (PCB# 1-503582 Rev A) has been inspected and is in good used condition. The PCB is clean with no visible damage, cracked traces, or broken connectors. All four RJ45 trunk ports and the rear Telco 50-pin RJ21 connector appear intact. There is light surface wear consistent with prior installation.
