To Clear a “Lost” Password
1) Remove power from the bridge/router.
2) Remove the screw securing the LAN / Console module to the rear of the
bridge/router. Be sure to grip the module only by the flange at the bottom of the
metal panel.
3) Unplug the LAN / Console module approximately 1/2 inch from the
bridge/router. Be sure to grip the module only by the flange at the bottom of the
metal panel. The module only needs to be removed slightly to disconnect the
module from the internal main board.
WARNING:
Because of the close proximity of the AC power from the power
coupler, do not insert anything into the LAN / Console opening while
the bridge/router is powered up.
4) Reattach the power to the bridge/router and wait for the power-up diagnostics to
finish. The Power LED will turn green.
5) Remove power from the bridge/router.
6) Re-install the LAN / Console module and secure it with the screw.
7) Power up the bridge/router.
8) Log into the bridge/router using the default password “BRIDGE” and change the
password as desired.
Changing LAN or WAN Interfaces
1) Remove power from the bridge/router.
2) Remove the screw securing the interface module to the rear of the bridge/router.
3) Remove the interface module from the bridge/router. Be sure to grip the module
only by the flange at the bottom of the metal panel.
4) Install the new interface module and secure it with the screw.
5) Power up the bridge/router.
Important: there must be a module in slot 1 (left side module position when viewed from
the rear of the unit) before a module in slot 2 (center position) will operate.
For IOLINK-520 models, if a LAN 2 module is installed it must go in slot 1. Note
in addition that installing a LAN 2 module will clear the IP address of LAN 1.
After installing a LAN 2 module, the IP address for both LANs must be entered.
Selecting MDI or MDI-X LAN Interface
For most LANs, where a number of devices are connected via a hub, this router will be
connected via the LAN cable to the MDI port. However, in locations where a single
workstation is to be connector to the router, the cable from the workstation should be
plugged into the MDI-X port. This eliminates the need for a hub at a remote site that has
only one LAN device.
