Chapter 3 Removing and Installing the PA-POS-1OC3

Replacing the SFP Optics Module

To remove the SFP optics module, perform the following steps:

Step 1 Attach an ESD wrist strap to your wrist and to the ESD connection socket on the chassis or to a bare metal surface on the chassis or frame.

Step 2 Disconnect the network fiber cable from the SFP optics module connector.

Step 3 Remove the SFP optics module from the slot.

a.Using your thumb and forefinger, grip the colored latching band on the front of the SFP optics module.

b.Gently push the latching band back toward the SFP slot. You may hear a click or feel the SFP optics module disengage from the holding latch.

Note Not all SFP optics modules have the same kind of latching mechanism.

c.While still holding the latching band, pull the SFP optics module forward and out of the slot.

Step 4 Set the SFP optics module aside on an antistatic surface.

Installing the SFP Optics Module

Use the following procedure to install the SFP optics modules:

Step 1 Attach an ESD-preventive wrist strap between you and an unpainted chassis surface.

Step 2 Verify that you have the correct SFP optics module for your installation.

a.Check the part number and distance information on the SFP optics module label.

b.If the distance information is not on the label, use the show controller pos x/y command to display the information after the SFP optics module is installed. See “Verifying the SFP Optics Module Installation” section on page 3-16for directions.

Step 3 Align the SFP optics module with the slot so that the label is facing away from the handle.

PA-POS-1OC3, PA-POS-2OC3 specifications

Cisco Systems has long been at the forefront of networking technology, providing solutions that empower organizations to enhance their connectivity and communication capabilities. Among its impressive lineup, the PA-POS-2OC3 and PA-POS-1OC3 modules stand out as significant components designed to optimize performance in service provider and enterprise environments.

The PA-POS-2OC3 and PA-POS-1OC3 modules are designed for use with the Cisco 7600 Series routers and are tailored for Packet Over SONET (POS) transport. Supporting the OC-3 speed of 155.52 Mbps, these modules provide reliable high-speed connectivity, enabling organizations to efficiently manage data traffic and ensure rapid data transfer across their networks. The PA-POS-2OC3 offers dual OC-3 capabilities, allowing for higher aggregate bandwidth and redundancy options, making it common in demanding network environments.

One of the main features of the PA-POS-2OC3 and PA-POS-1OC3 is their enhanced support for advanced networking protocols, including MPLS (Multiprotocol Label Switching). MPLS facilitates efficient data routing and improves bandwidth utilization by enabling multiple types of traffic to be consolidated over a single network. This is crucial for organizations looking to deploy services like VoIP, video conferencing, and other bandwidth-intensive applications.

The modules also offer robust error correction and monitoring capabilities, which are essential for maintaining service quality in mission-critical applications. Administrators can monitor performance and diagnose issues in real-time, enabling swift responses to potential concerns that could disrupt service.

Moreover, the PA-POS-2OC3 and PA-POS-1OC3 are designed with features that support enterprise-grade security and scalability. This is particularly beneficial for organizations expecting growth or requiring enhanced protection for sensitive data as it traverses the network.

In summary, Cisco's PA-POS-2OC3 and PA-POS-1OC3 modules represent essential building blocks for high-speed networking solutions. Their support for OC-3 connectivity, advanced routing protocols, and robust monitoring capabilities make them ideal for both service providers and enterprises. Through increased scalability, improved bandwidth management, and enhanced security, these modules allow organizations to adapt to the ever-evolving landscape of data communications effectively. With Cisco at the helm, businesses can trust in a networking solution that not only meets current demands but is also primed for future growth.
