Connecting the Chassis Grounding Cable

Before installing any other cable, you should first attach the chassis ground cable to the server's chassis grounding studs. Refer to the Chapter 5 for the site requirements for this section.

1. Obtain a chassis grounding cable from your site and two M5 nuts with lock washers from the ship kit.

2. Go to the back of the server and locate the two chassis grounding studs (see FIGURE 4-3).

3. Position and align the chassis grounding cable against the two grounding studs at the rear of the chassis.

  FIGURE 4-3 Location of Chassis Grounding Studs

Figure showing the location of the grounding studs and where to connect the grounding cable.

4. Tighten the two M5 nuts to secure the grounding cable to the two studs.

5. Secure the other end of the grounding cable to the earth ground in the building.

You can secure the grounding cable to a proper grounding point on the rack, as long as the rack is properly grounded to the earth ground in the building.

Caution - An electrical hazard is present if energized units are not properly grounded.




Connecting the Data Cables

This section provides information about the rear panel cable connections.



Note - See Chapter 5 for complete information about assembling and connecting the power cables.



Gigabit Ethernet Ports

The Netra 240 server has four autonegotiating 10/100/1000BASE-T Gigabit Ethernet system domain ports. All four Ethernet ports use a standard RJ-45 connector, the transfer rates for which are given in TABLE 4-2. FIGURE 4-4 shows the pin numbering of the ports, and TABLE 4-3 describes the pin signals.

Network Management Port

The server has one 10BASE-T Ethernet management domain interface, labelled NET MGT. For information on configuring this port for managing the server with ALOM, see the Sun Advanced Lights Out Manager User Guide for the Netra 240 Server
(
817-3174).



caution icon

Caution - If you are planning to use the network management (NET MGT) port, you must use a shielded Ethernet cable to maintain your server's NEBS compliance. The cable's shield must be grounded at both ends.

Serial Management Port

The serial management connector (labeled SERIAL MGT) is an RJ-45 connector that can be accessed from the back panel. This port is the default connection to the system, and you should use this port only for server management.



caution icon

Caution - You must use a shielded Ethernet cable to maintain your server's NEBS compliance. The cable's shield must be grounded at both ends.
