Chapter 1: Overview of the SafeGuard Controller
Power Supplies
The SafeGuard Controller is available in either of the following power configurations:
■
Dual AC power supplies
■
One AC power supply and one DC supply input
The system is fully functional with one power cord connected; however, to ensure that
your system is operational at all times, install both power cords and make sure that both
power cords are connected to different circuits. When one power source fails, the
secondary power source becomes the new power source for the SafeGuard Controller.
For uninterrupted operation, it is preferred that one circuit have battery backup. In this
way, even if one circuit malfunctions, the system still remains operational with the help of
the power supplied by the secondary power source.
The AC power supply for the SafeGuard Controller has a voltage range from 100 to 240
VAC with a maximum current of 2.2 A at 100 VAC. The DC power input has a maximum
current of 3.1 A at 48 VDC.
With both AC power supplies connected, the maximum power that is drawn is no more
than 2.2 A at 100 VAC from an AC supply or 3.1 A at 48 VDC from a DC supply.
Small Form-Factor Pluggable (SFP) Modules
The SafeGuard Controller supports both fiber and copper SFP modules. You can mix and
match different types in the same unit.
The SafeGuard Controller uses any of the following types of SFP modules:
■
1000BASE-LX single-mode fiber
■
1000BASE-SX multi-mode fiber
■
10/100/1000BASE-T
18
CAUTION: The SafeGuard Controller has redundant power supplies. You
must disconnect both power cords to completely remove power from the
unit.
NOTE: SFP modules can operate at 10, 100, or 1000 Mbps in full-duplex mode
or 10 or 100 Mbps in half-duplex mode.
