1. Prior to Starting
MFR-41CPU is an optional redundant CPU card for MFR-4100 units.
MFR-61CPU is an optional redundant CPU card for MFR-6100 units.
The MFR-41CPU/MFR-61CPU is specifically designed for the MFR-4100/MFR-6100. A standard MFR-
4100/MFR-6100 comes with a single CPU card installed into one of its two CPU slots. The optional
MFR-41CPU/MFR-61CPU allows you to operate the MFR-4100/MFR-6100 continuously, even if one
CPU card fails.
CAUTION
Installing this option, which requires accessing the unit interior by opening the panel,
should only be done by qualified technical personnel.

2. Installation / Replacement of MFR-41CPU
2-1. How to Install a New Card (if only one card installed)
This section describes how to install a new MFR-41CPU and change the CPU from a standalone
configuration to a redundant configuration.
IMPORTANT
Do not touch any components on the MFR-41CPU to protect it from electrostatic damage.
The following procedure shows how to install the CPU2 card (MFR-41CPU).
(1) Unfasten four fixing screws on the front panel and detach the front panel.
(2) Insert a new CPU card (MFR-41CPU) firmly
into its slot.
(3) Tighten the fixing screw on the CPU card
(MFR-41CPU).
(4) Re-install the front panel.
(5) Insert LAN cables into CPU2 MFR-LAN and PC-LAN ports and connect the cables with
respective hubs.
(6) If necessary, configure the network settings
for CPU2 and the settings for the number
of CPU operating days.
(See “Main Unit Settings” for network
settings and “Warning of CPU Consecutive
Operating Days/ Automatic Reboot” in the
MFR-4100/6100 Web Control Operation
Manual.)
The card installation is now complete.
