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. Refer to Section 8.6.1, “Failure of Network
Communications,” in the Ultra Enterprise 3000 System Manual (p/n 802-6051),
and refer to the manual provided with your hub.
1.6 Preparing the Area
Use the following guidelines to prepare a location for your server.
•
The server unit requires approximately 1.5 feet (47 cm) of space in the front
and back for access by service personnel. See Figure 1-4.
•
A minimum space of 6 inches (16 cm) is required on both sides of the server
to afford adequate air flow.
Warning –
To avoid exhaust air recirculation, do not put systems or
peripherals next to each other, side by side.
•
Keep power and interface cables clear of foot traffic. Route cables inside
walls, under the floor, through the ceiling, or in protective channels. Route
interface cables away from motors and other sources of magnetic or radio
frequency interference.
