They enable security, mobility, application performance, video, and energy savings over an infrastructure that supports resiliency, virtualization, and automation. Cisco Catalyst Series Switches provide borderless performance, scalability, and services with reduced total cost of ownership TCO and superior investment protection. The Cisco Catalyst Figure 1 has a centralized forwarding architecture that enables collaboration, virtualization, and operational manageability through simplified operations. With forward and backward compatibility spanning multiple generations, the new Cisco Catalyst E Series provides exceptional investment protection and deployment flexibility to meet the evolving needs of organizations of all sizes. Integrated resiliency in both hardware and software minimizes network downtime, helping to ensure workforce productivity, profitability, and customer success.

This process will take a couple of minutes and will have no negative impact on the R switch. Notice the software image the system is reporting for both Supervisor Engines.
Our current active Supervisor Engine is running version SG, while our standby Supervisor Engine is running version SG — the new IOS loaded! To initiate the Supervisor Engine switchover, use the redundancy force-switchover command as shown below: R redundancy force-switchover This will reload the active unit and force switchover to standby[confirm] Preparing for switchover.. Reason: Stateful Switchover. This is normal expected behaviour — do not be alarmed!
Apart from the switch cutting our telnet session, users will not notice any service disruption — the switchover will be completely transparent to them no matter the network load during the switchover. To reconnect to the switch, simply telnet back into the same IP address.
If connected via console cable it will be necessary to connect it to the new active supervisor engine in order to continue controlling the switch. Engineers who would like to monitor, via telnet or direct console cable connection to the new active engine , the reload progress of the Supervisor Engine can use the show module command. In addition the redundancy status of the first engine is Disabled — an expected result since the Supervisor Engine SE1 has not booted yet.
We also covered the IOS upgrade process for redundant Supervisor Engine configurations, how to force a Supervisor Engine switchover and monitoring the Supervisor Engine bootup and sync process.

Many might be aware of our first R article that covered the installation of a Cisco Catalyst R-E switch. Apart from these minor cosmetic changes the switch looks exactly the same as its predecessor. The dual power supplies are positioned at the top part of the switch and the specially designed grid allows adequate air to be pumped through the power supplies and out the back, with the help of the massive power supply fans. The fans used are extremely high quality with very little friction — when during our test run, we switched off the power supplies, the fans continued to spin for at least another 20 seconds before coming to a complete stop: Mounting a Catalyst into a rack can be a daunting experience, mainly due to its weight. To overcome the problem of installing the heavy switch, we decided to remove both power supplies and all cards from the chassis. The empty chassis made things much easier. Naturally, we had to capture this moment and here it is in all its glory: We should note that extreme caution must be given when removing and inserting the cards.
