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

Online Insertion and Removal

Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter components or connector pins. (See Figure 3-1.)

Online Insertion and Removal

Several platforms support online insertion and removal (OIR) of port adapters; therefore, you do not have to power down routers when removing and replacing a PA-POS-1OC3 in the Cisco 7200 VXR routers, Cisco 7201 router, Cisco 7301 router, or Cisco 7401ASR router.

For the Cisco 7304 router, you must remove the Cisco 7304 PCI port adapter carrier card before removing or replacing port adapters.

For Cisco 7500 series routers, you must remove the VIP before removing and replacing port adapters.

For Cisco 7600 series routers, you must remove the FlexWAN module before removing or replacing port adapters.

It is wise to gracefully shut down the system before removing a port adapter or module that has active traffic moving through it. Removing a port adapter or module while traffic is flowing through the ports can cause system disruption. Once the port adapter or module is inserted, the ports can be brought back up.

Note As you disengage the port adapter from the router or switch, online insertion and removal (OIR) administratively shuts down all active interfaces in the port adapter.

OIR allows you to install and replace port adapters or service adapters (carrier cards, VIPs and FlexWAN modules) while the router is operating; you do not need to notify the software or shut down the system power, although you should not run traffic through the port adapter you are removing while it is being removed. OIR is a method that is seamless to end users on the network, maintains all routing information, and preserves sessions.

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.
