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
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, the other 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 power supplies page.
Hard Disk
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 here
