Power Supply
Each FR6822+ frame can house two redundant, modular, and fully self-contained power
supply units (PSU). All FR6822+ frames come with one AC or DC power supply, which can
support an entire frame load. An optional redundant AC or DC power supply can be
ordered separately. Power supply configurations can be a mix of AC and DC units.
Each PSU is hot-swappable, ensuring no disruption to frame operation. Other features of
both power supplies include the following:
Allows frame monitoring of PSU
Includes power switch on front of PSU unit
Maintains compatible output rails ±6.8 V for 6800 and 6800+ products
The 6822+AC auto-switches 90 to 240 V AC, at 47 to 63 Hz. “Power” and “Fault”
indicators are located on the front of the PSU.
The 6800+48V supports a -48 VDC input and provides DC PSU protections including input
fuse, inrush current limiting, input transient protection, short circuit protection on all
outputs, and reverse input voltage protection. It provides a Power Good green LED and an
Overheat red LED.
See Figure 1-2 on page 3 to locate the PSU units in the FR6822+ frame, or
Power Supplies on page 75 for a more detailed description.
6800+ETH
Resource
Module
If a frame has no resource module, no remote control will be available, and control of the
frame’s modules will be at the card edge only.
The 6800+ETH resource card allows communication between 6800+ devices and CCS™
software applications such Navigator™, and provides a communication interface between
CCS control panels such as NUCLEUS.
The 6800+ETH module provides 10/100Base-T Ethernet access, while the CCS software
application provides a graphical user interface (GUI).
Figure 1-5 is a top-front view of the 6800+ETH module. Descriptions of card-edge
components are found in Table 1-2.
