Learn to check hardware faults in the Cisco router Module

Many friends who use the Cisco router module have encountered many problems during use. Below are some basic solutions. More or less can solve some small problems. Problem description: The Cisco router module does not turn on the light, and does not turn on the light after it is turned on.

Answer: If the module is broken, I have encountered this situation. Check if you recognize this Cisco router module after it is started up. If you do not know this module, use the show diag command to check whether the slot knows this module or not, indicates that the module hardware is faulty. Try another one, and the slot of the machine is not ruled out. It may be that the ios version is too low. Troubleshoot the problem by yourself.

1. Check whether the Cisco router module is properly inserted.
2. Check whether your IOS Service supports this module on the Internet.
3. The show diag mentioned above can also be viewed!

"Cisco's Cisco2600 series, the most common and typical Router model, is used as an example. In earlier vrouters such as the Cisco2500 series, Cisco has fixed interfaces. Starting from the Cisco2600 series, Cisco has adopted modular interfaces, some interface interfaces and network modules) the customer will purchase the product based on their own needs, which makes Cisco router products highly scalable. Cisco's Cisco2600 series routers have enterprise-level versatility, integration, and scalability. With the emergence of new enterprise applications, the modular structure of this series can adapt to the changes in network technology, and can be upgraded by replacing the interface card and the network Cisco router module.

The Cisco2600 series is equipped with a powerful RISC processor that supports advanced service quality QoS), security, network integration, and other services. The Cisco2600 series and Cisco1600, 1700, And 3600 series share the Cisco router modular interfaces, provides comprehensive solutions for Internet, Intranet access, Voice/Data Integration, analog and digital dial-up access services, VPN access, ATM access, VLAN, and route management. This series of routers is currently the most used by small and medium-sized enterprises. They are fully capable of adapting to the evolving network application needs of small and medium-sized enterprises, although it is defined by Cisco as "used in the branches of small and medium-sized enterprises", users who do not have very high requirements often use it at the core of the network.

Cisco's Cisco2600 series include: 2610, 2611, 2613, 2620, 2621, 2650, and more Cisco has stopped selling globally) and 2610XM, 2611XM, 2612, 2620XM, 2621XM, 2650XM, 2651XM, and 2691 are on sale.) See Figure 1 ). Table 1 shows the basic configurations of the currently sold Cisco2600XM and 2612 and 2691 interfaces. In the Cisco2600 series, some interfaces are fixed, while some interfaces are Cisco router modular design.

Users can choose to install it in WAN Interface slots and network module slots. The fixed configuration interfaces include: Auxiliary Port AUX) and control port CON). The ETHERNET port of the state network port has one or two. The TR of the Ling ring has only one of Cisco2612 and Cisco2613. The others are interfaces, modules, and combinations of modules and interfaces. We will introduce them separately below. We can see their positions in the rear panel of the router in combination with the diagram.
