Point
attach labels to the cables and make a note of connection origins and
destinations.
• The ETERNUS2000 has two LAN ports (10BASE-T/100BASE-TX,
MNT port and RMT port) for each controller.
- For device management via setting/maintenance program or
ETERNUSmgr, use MNT port.
- For remote support operation, use MNT port or RMT port. For
remote support on a different network to the customer network,
use the RMT port as the remote support port. For remote support
over the customer network, only the MNT port need be used.
- Operation using only the RMT port without the MNT port is not
allowed.
• The ETERNUS2000 LAN ports operate by default in Auto-Negotia-
tion mode, which recognizes 10BASE-T/100BASE-TX, and Full
duplex / Half duplex automatically.
- When connecting networking equipment such as hubs and rout-
ers, check the specifications and settings of the equipment to be
connected.
- When the LAN ports of the device to be connected operate in
Auto-Negotiation mode, the communication mode is set by the
specified algorithm.
- When the device cannot be recognized correctly, set both devices
to be connected in Fix mode.
• When hub has Spanning Tree Protocol (STP) function and it is
enabled, connection to the ETERNUS2000 may fail. If failed, disable
the STP function.
- When STP function is not necessary for network configuration,
disable the function for hub.
- When STP function is necessary for network configuration, dis-
able the function for the connected port of hub.
