A Cisco SFP transceiver module providing one RJ-45 port for 10/100/1000Base-T Gigabit Ethernet over twisted pair, compatible with Nexus 7700 F3-Series, 9372PX and 9396PX switches
This Cisco SFP transceiver module provides a single RJ-45 port for 10/100/1000Base-T connectivity over twisted pair cabling. It operates at a 1 Gbps transfer rate for data networking applications. The module follows the mini-GBIC form factor for hot-swappable installation in compatible Cisco switching equipment. It is designed for network administrators expanding copper-port density.
The transceiver replaces 10/100 Mbps copper modules or populates vacant SFP ports to deliver gigabit speeds to endpoints. The jump is worthwhile when link negotiation must reach 1000Base-T across existing Cat5e or better structured cabling. It supports the TCP/IP protocol suite for standard LAN traffic. Network engineers typically deploy it when bandwidth demands exceed Fast Ethernet capacity.
Confirm the target switch accepts the GLC-TE part number; the manufacturer lists compatibility with Cisco Nexus 7700 F3-Series, 9372PX and 9396PX platforms. Ensure an SFP slot is available and that the link partner auto-negotiates 1000Base-T over the twisted pair medium. No other copper media types are supported by this module. Check the switch software release for transceiver recognition.

The module uses a standard SFP cage and a single RJ-45 port, so it fits any switch that accepts mini-GBIC form-factor transceivers.
The bail latch must click fully closed to seat the electrical contacts; a loose latch causes link flapping.
Persistent CRC errors, negotiated speed dropping to 100 Mbps, or a port that stays down after cable swap indicate the PHY is failing.
