There are several types of redundant features that many of today’s networking products offer. These features are found in both hardware and software.
Power supplies One way to ensure uptime is to employ load sharing, redundant power supplies in switching, routing and media converter chassis. Most manufacturers offer these types of options for their chassis based solutions. Another way to ensure power redundancy is to use a backup UPS unit. Should the main power fail, your systems would stay powered via battery packs in the UPS unit.
Hot Swap Modules Many GBIC and switching or routing blades are designed to be hot swappable meaning they can be replaced on the fly while the main system/chassis is still powered up. This saves time when a component on a blade or module fails.
