SSG 20 Hardware Installation and Configuration Guide
Antennae Types
The SSG
Diversity antennae — The diversity antennae provide 2dBi directional coverage and a fairly uniform level of signal strength within the area of coverage and are suitable for most installations. This type of antennae is shipped with the device.
External omnidirectional antenna — The external antenna provides 2dBi omnidirectional coverage. Unlike diversity antennae, which function as a pair, an external antenna operates to eliminate an echo effect that can sometimes occur from slightly delayed characteristics in signal reception when two are in use.
External directional antenna — The external directional antenna provides 2dBi unidirectional coverage and is appropriate for locations like hallways and outer walls (with the antenna facing inward).

2.Save the files from the USB storage device to the internal flash storage on the device with the save {software config
3.Before removing the USB storage device, stop the USB port with the exec
4.It is now safe to remove the USB storage device.
