If you are attaching your network to the ESSNet hub, you also need to provide an
Ethernet cable and TCP/IP information to IBM. IBM will connect your LAN cable to
the ESSNet hub after the ESS and the ESSNet are installed and in operation.
You are responsible for firewall protection for the ESSNet.
You also need to provide a table or a stand for the ESSNet workstation at your site.
The workstation is a personal computer (PC) and a monitor. The weight and
dimensions for the PC are:
PC weight
PC height
PC width
PC depth
The approximate weight and dimensions for the monitor are:
Monitor weight
Monitor height
Monitor width
Monitor depth
The monitor has a 75 mm (15 in.) screen. The combined weight of the monitor and
the PC does not exceed 30 kg (65 lbs).
Power requirements
This section provides power and cooling requirements and environmental
information for the ESS.
Input voltages and frequencies
See Table 14 for the input voltages and frequencies that the ESS supports. The
values apply to both primary power cables on any expansion enclosure or any
model. Inputs are either single phase or balanced three phase depending on the
connector type as described in "Power cable connectors" on page 61. Also see
"Power features" on page 25 for information about power features.
Power consumption and environmental information
Table 15 on page 59 gives power consumption and environmental information on
the ESS.
