3. Installation / Replacement of MFR-61CPU
3-1. How to Install a New Card (if only one card installed)
This section describes how to install a new MFR-61CPU and change the CPU from a standalone
configuration to a redundant configuration.
IMPORTANT
Do not touch any components on the MFR-61CPU to protect it from electrostatic damage.
(1) Unfasten four fixing screws on the front panel and
detach the front panel.
(2) Insert a new CPU card (MFR-61CPU) firmly into its slot.
(3) Tighten the fixing screw on the CPU card (MFR-61CPU).
(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.
