MPORTAN

• The ETERNUS DX60/DX80/DX90 LAN ports operate by default in Auto-

Negotiation mode, which recognizes 1000Base-T/100Base-TX/10Base-

T, and Full duplex / Half duplex automatically.

- When connecting networking equipment such as hubs and routers,

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 ETERNUS DX60/DX80/DX90 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, disable

the STP function of the hub port or perform the Port-Fast setting only

for the ETERNUS DX60/DX80/DX90 connection.
