Note – Multiplexer boxes require a transceiver when used with the Ethernet
applications described in this manual. Although these transceivers are
compatible with Sun equipment, Sun Microsystems does not guarantee the
performance of any component that was not purchased from Sun.
Many transceivers are compatible with both level-1 and level-2 Ethernet. To
operate these transceivers with Sun equipment, set the device for level-2
operation following the manufacturer’s instructions.
Sun equipment conforms to the Ethernet 10/100BASE-T standard, which states
that the 10/100BASE-T Link Integrity Test function should always be enabled
on both the host and the hub. If you have problems verifying connection
between Sun equipment and your hub, verify that your hub also has the link
test function enabled. See Section 3.4, “Failure of Network Communications,”
and refer to the manual provided with your hub.
1.6 Preparing the Area
1.6.1 Floorspace for the Enterprise 6000/5000 Cabinet Systems
•
The server cabinets require approximately four feet (122 cm) of space in
front and three feet (92 cm) in back for access by service personnel. See
Figure 1-7.
•
Allow two inches (5 cm) of space on the left for adequate air flow.
•
Allow two inches (5 cm) of space on the right for adequate air flow.
•
The server system (including expansion cabinets) should have a dedicated
AC breaker panel. The server system should not share this breaker panel
with other, unrelated equipment.
•
Keep power and interface cables out of the way of foot traffic. Cables can be
routed inside walls, floors, ceilings, or in protective channels. Interface
cables should be routed away from motors and other sources of
electric/magnetic or radio frequency interference.
