Replace an FPC in an M40e or M160 Router

Replace an FPC in an M40e or M160 Router

Do not leave a transceiver uncovered. The safety cap keeps the port clean and prevents accidental exposure to laser light.

Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

6.If you need to remove or replace PICs in an M40e-FPC1 or M40e-FPC2 or on an

M160 router, perform the removal or replacement now, before removing the FPC from the chassis. For instructions, see the M40e Internet Router Hardware Guide or

M160 Internet Router Hardware Guide. If removing or replacing PICs in an M40e-FPC, wait until Step 11.

7.Unscrew the thumbscrews at the top and bottom of the FPC.

8.Pull the ends of the ejector levers, which are adjacent to the thumbscrews, away from the face of the FPC until they are nearly perpendicular to it (see Figure 11, which shows an M160 router).

9.Grasp the FPC with both hands and slide it about halfway out of the chassis.

10.Place one hand under the FPC to support it and slide it completely out of the chassis. Set the FPC on the antistatic foam mat prepared in Step 1.

The weight of the FPC is concentrated in the back end. Be prepared to accept the full weight—up to 15 lb (6.8 kg)—as you slide the FPC out of the chassis.

Do not hold the FPC by the ejector levers, bus bars, or edge connectors. They cannot support its weight.

To avoid damaging any components, use extra care when laying an M40e-FPC component-side down on the antistatic mat, particularly if the mat is not made of foam.

Do not stack the FPC on top of or under any other component.

11.If removing or replacing PICs on an M40e-FPC, see the instructions in “Replace a PIC in an M40e-FPC” on page 20.

M40e, M40 specifications

Juniper Networks M40 and M40e are high-performance, modular routers designed to provide scalability, flexibility, and advanced capabilities for service providers and large enterprises. These platforms have made a significant impact in the networking industry due to their robust architecture and rich feature set.

The Juniper M40 was introduced as a key player in the routing landscape, emphasizing performance and reliability. It is based on the innovative Junos operating system, which enables operators to manage network resources effectively. The M40 router features a flexible modular design, allowing for the installation of various interface cards that support multiple protocols and speeds. This versatility is crucial for adapting to evolving network demands.

One of the standout features of the M40 is its high throughput capability, supporting up to 40 Gbps with exceptional performance under heavy loads. This is complemented by advanced queuing and scheduling options that ensure efficient traffic management. The M40 also implements sophisticated routing protocols, such as BGP, OSPF, and MPLS, enabling service providers to enhance their network infrastructure with robust routing features.

The M40e variant enhances the original model with additional features and improved performance metrics. It is built for even greater scalability, supporting more interface types and higher capacities. The enhanced hardware of the M40e allows it to process data packets with lower latency, ensuring optimized performance for real-time applications such as voice and video.

Both M40 and M40e routers utilize a redundant architecture, providing high availability and fault tolerance. This is crucial for mission-critical applications where downtime can lead to significant operational disruptions and financial losses. The routers also boast advanced security features, including support for IPsec and various access control mechanisms, ensuring data integrity and confidentiality across the network.

In summary, the Juniper Networks M40 and M40e routers represent a significant evolution in networking technology. Their modular architecture, high throughput capabilities, advanced routing protocols, and robust security features make them ideal choices for service providers and enterprises looking to build resilient and high-performance networks. With their proven reliability and performance, these routers continue to serve as a foundation for modern networking solutions.
