Preparing for Installation 1-7

Caution – Do not make mechanical or electrical modifications to the server
cabinet. Sun Microsystems® is not responsible for the regulatory compliance if
the cabinet is modified.
1.3.2 Enterprise 4000 System
The 8-slot Enterprise 4000 system uses nominal input voltages of 100-120 VAC
or 200-240 VAC. Sun products are designed to work with single-phase power
systems having a grounded neutral conductor.
To reduce the risk of electrical shock, do not plug Sun products into another
type of power source. Contact your facilities manager or a qualified electrician
if you are unsure what type of power is supplied to your building.
1.4 Preparing the Air Conditioning
For the most reliable system operation:
• The room should have sufficient air-conditioning capacity to support the
cooling needs of the entire system.
• The air-conditioning system should have controls that prevent excessive
temperature changes.
1.5 Preparing the Ethernet Network
The Enterprise 6000/5000/4000 systems follow the IEEE standard for
10/100BASE-T Ethernet (twisted-pair) or MII (Media Independent Interface).
Twisted-pair cables used with Sun Microsystems products have RJ-45
connectors that resemble the smaller RJ-11 connectors used for modular
telephone cables. For twisted-pair cable length, see Chapter 2, Table 2-1 on
page 2-9.
A MII to AUI converter cable, available from Sun, enables the 10/100 Mbps
Ethernet interface to run over 10 Mbps coaxial Ethernet networks. Other MII
Ethernet connectivity products are available from third parties.
Figure 1-5 and Figure 1-6 illustrate types of network cables and possible
implementations of 10/100BASE-T Ethernet.
