1. Produktet er slutview
The Juniper Networks QFX-EM-4Q is an expansion module designed for the QFX5100-24Q switch. It provides four additional QSFP+ ports, significantly increasing the port density and connectivity options of the host switch. This module is engineered for seamless integration and can be hot-inserted or hot-removed without disrupting the switch's normal operation.
Each QSFP+ port on the QFX-EM-4Q is configured as a native 40 Gigabit Ethernet (GbE) port, supporting high-speed data networking and optical network applications. It is a critical component for expanding the capabilities of your Juniper QFX5100 series switch infrastructure.

This image displays the module's faceplate, featuring four QSFP+ transceiver slots, various indicator LEDs, and two RJ45 Ethernet ports for management or other functions. The module also includes mounting screws on either side for secure installation into a compatible switch chassis.
2. Nøglefunktioner
- Enhanced Port Density: Adds four QSFP+ ports to the QFX5100-24Q switch.
- Højhastighedsforbindelse: Each QSFP+ port supports native 40 Gigabit Ethernet.
- Hot-Swappable: Can be inserted or removed while the switch is operational, minimizing downtime.
- Sømløs integration: Designed specifically as a companion module for the Juniper QFX5100-24Q.
- Data Networking & Optical Network Support: Ideal for high-bandwidth applications.
3. Installation og opsætning
This section provides instructions for safely installing the QFX-EM-4Q expansion module into a compatible Juniper QFX5100-24Q switch.
3.1 Sikkerhedsforanstaltninger
- Ensure the switch is properly grounded before installation.
- Wear an electrostatic discharge (ESD) wrist strap connected to a grounded surface when handling the module.
- Do not force the module into the slot; it should slide in smoothly.
- Refer to the QFX5100 switch documentation for specific chassis slot locations and power requirements.
3.2 Installationstrin
- Identify an available expansion module bay on the front panel of your QFX5100-24Q switch. The QFX5100-24Q has two such bays.
- If a blank panel is installed, carefully remove it by loosening any retaining screws and pulling it out.
- Orient the QFX-EM-4Q module so that the faceplate aligns with the switch's front panel and the module slides into the bay correctly.
- Gently slide the module into the bay until it is fully seated. You may feel a slight click as it connects to the backplane.
- Secure the module in place by tightening the captive screws on either side of the module's faceplate.
- Once installed, the switch should automatically detect the new module. Verify its status through the switch's command-line interface (CLI) or management interface.
4. Betjening
The QFX-EM-4Q module operates as an integrated part of the Juniper QFX5100-24Q switch. Once installed and detected, its QSFP+ ports become available for configuration and use.
4.1 Portkonfiguration
The four QSFP+ ports on the QFX-EM-4Q module are designed to operate as native 40 Gigabit Ethernet interfaces. They do not support channelization into multiple 10GbE links. Configuration of these ports, including IP addressing, VLAN assignments, and routing protocols, is performed via the Juniper Junos OS CLI or J-Web interface, similar to other ports on the QFX5100 switch.
Refer to the Juniper Networks Junos OS documentation for detailed instructions on configuring network interfaces and services.
4.2 Statusindikatorer
The module may feature LED indicators on its faceplate to provide visual status. Common indicators include:
- Status-LED: Indicates the overall operational status of the module (e.g., green for operational, amber for fault).
- Link/aktivitet LED'er: Per-port LEDs indicating link presence and data activity for each QSFP+ port.
Consult the QFX5100 switch hardware guide for a precise description of all LED behaviors.
5. Vedligeholdelse
The QFX-EM-4Q expansion module is designed for high reliability and requires minimal routine maintenance. However, proper handling and environmental conditions are crucial for its longevity.
5.1 Rengøring
- Keep the module's ports and connectors free from dust and debris.
- Use a lint-free cloth and, if necessary, a mild, non-abrasive cleaning solution specifically designed for electronic components.
- Ensure all power is disconnected from the switch before performing any cleaning that involves removing the module.
5.2 Miljøhensyn
- Operate the module within the specified temperature and humidity ranges of the QFX5100 switch.
- Ensure adequate airflow around the switch chassis to prevent overheating.
6. Fejlfinding
This section provides basic troubleshooting steps for common issues encountered with the QFX-EM-4Q expansion module.
6.1 Module Not Detected
- Re-seat the Module: Carefully remove the module and re-insert it, ensuring it is fully seated and the captive screws are tightened.
- Bekræft kompatibilitet: Confirm that the QFX-EM-4Q is compatible with your specific QFX5100 switch model and Junos OS version.
- Check Switch Status: Ensure the host QFX5100 switch is powered on and operating normally.
6.2 Problemer med portlink
- Tjek kabler: Ensure QSFP+ transceivers and fiber optic cables are correctly installed and not damaged.
- Verify Transceiver Compatibility: Use only Juniper-supported QSFP+ transceivers.
- Portkonfiguration: Confirm that the port is enabled and correctly configured in Junos OS.
- Peer Device Status: Check the status of the device connected to the QSFP+ port.
6.3 Persistent Faults
If issues persist after basic troubleshooting, consult the Juniper Networks technical documentation for the QFX5100 series switches or contact Juniper Networks technical support for assistance.
