■LAN for remote support

Various failures that occur in the ETERNUS DX Disk storage system are notified to the remote

support center. Remote support connection can be separated from the LAN for operation man-

agement.

3.3 Power Supply Connection

Connect the power cords (AC cables) of the ETERNUS DX Disk storage system to the power

sockets, the UPS sockets, or the power control unit sockets.

Refer to "2.5 Outlet/Socket Specifications" (page 31) for details about the types and the number

of power outlets/sockets.

3.3.1 Input Power Supply Lines

Multiple power supply facilities in the building or UPS units are recommended for power supply

redundancy. When the ETERNUS DX Disk storage system power supply is redundantly config-

ured, business can continue even if one of the power lines fails.

To connect the ETERNUS DX Disk storage system to power supply facilities, use the following

configurations to improve the availability of the power supply facilities if a power supply facility

failure occurs.

•Connect the power cords of PSU#0 and PSU#1 to different lines.

•When a power distribution unit is used, separately connect it to line 0 (PSU#0) and line 1

(PSU#1).

Alternatively, optimal system design (including the server) may instead lead to the ETERNUS DX

Disk storage system being configured with only a single power supply facility or UPS unit. Which

configuration is selected will depend on system availability requirement considerations.

Figure 3.6 Dual-line power supply when connecting to power sockets

Two power supply units (PSU#0 and PSU#1) are installed in each enclo-

sure. Make sure that power cords are connected to both of the power sup-

ply units.
