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.
Refer to Appendix A, “Specifications,” in the Ultra Enterprise 3000 System
Manual for environmental information.
1.5 Preparing the Ethernet Network
The Enterprise 3000 system follows 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.
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 1-2 and Figure 1-3 illustrate types of network cables and possible
implementations of 10/100BASE-T Ethernet.
Set up the network using Sun or third party components. To obtain the best
results, read any applicable manufacturer instructions. Be aware that Sun
Microsystems cannot guarantee the performance of any components that are
not purchased from Sun.
