The [[TMG7800]] was designed for high-capacity, high-performance and high availability in mind.

There are 3 features available for the [[TMG7800-CTRL]]

== TMG-CONTROL Redundancy ==

When dealing with a high capacity system, TelcoBridges recommends to use 2 [[TMG7800-CTRL]] units. The goal is to minimize down time in case of failure. When 2 [[TMG7800-CTRL]] units work in redundancy, 1 is considered as [[Active/Standby|Active]], the other [[Active/Standby|Standby]].

Here is an example [[TMG7800-CTRL]] unit switchover:

== Dual Power Supply ==

Each of the [[TMG7800-CTRL]] contains dual AC or DC power supplies. For more details, see the [[Redundancy_%26_High_Availability:Power_Supply|power supplies]] page.

== Hard Disk Redundancy ==

One of the most common failure for server are hard disk failure. Which is why all [[TMG7800-CTRL]] units are supplied with 2 hard disks setup in RAID1. It is important to mention that the hard disks are hot-swappable.

Procedure to replace a hard disk is available [[TMG:Replace_Hard_Disk|here]]
