Cabling the Server |
This chapter provides instructions for cabling the server. Topics include:
Note - Both AC and DC versions of the server must be installed in a restricted-access location. |
Caution - The Sun Netra T5220 must not be directly connected to Outside Plant cables. |
The following list describes the server’s cable connections and ports:
FIGURE 5-1 shows the connectors on the rear panel of the Sun Netra T5220 server.

To boot the server, you must connect and configure the network and serial ports. The procedures are given in the following sections.
The server also has serial and USB ports available for connections to optional devices (see Cable Connections and Ports).
Note - When you are finished connecting the cables to the server, ensure that the server can slide smoothly in and out of the rack without binding or damaging the cables. |
To Connect the Service Processor Serial Management Port |
The service processor serial management port is marked SER MGT (FIGURE 5-3). It is the leftmost RJ-45 port on the rear panel.
Note - The cable and DB-9 RJ-45 adapters are for the host serial port, and not for the server SER MGT port. |
FIGURE 5-3 Service Processor Serial Management Port - Rear Panel
Use this port for server management. This port is needed to set up the service processor network management port, as detailed in Enabling the Service Processor Network Management Port.
Note - Use the service processor serial management port only for server management. It is the default connection between the service processor and a terminal or a computer. |
Caution - Do not attach a modem to this port. |
Connect a Category 5 cable from the SER MGT serial management port to the terminal device.
When connecting either a DB-9 or a DB-25 cable, use an adapter to perform the crossovers given for each connector.
To Connect the Service Processor Network Management Port |
The service processor network management port is labeled NET MGT (FIGURE 5-4). It is located just to the right of the serial management (SER MGT) port on the rear panel.
FIGURE 5-4 Service Processor Network Management Port - Rear Panel
Note - This port is not operational until you configure the network settings (through the serial managment port), as detailed in Configuring the Service Processor Network Management Port. |
Note - If you have access to a DHCP server on the network, you can see the service processor get an IP address because the DHCP client is enabled by default. |
Note - The service processor network management port is configured by default to retrieve network settings with Dynamic Host Configuration Protocol (DHCP) and allow connections using Solaris Secure Shell (SSH). You might need to modify these settings for your network. Instructions are given in Chapter 6. |
Connect a Category 5 cable from the NET MGT network management port to your network switch or hub.
To Connect the Ethernet Network Cables |
The server has four network connectors, marked NET0, NET1, NET2, and NET3 (FIGURE 5-5). These connectors are RJ-45 Gigabit Ethernet.
FIGURE 5-5 Service Processor Ethernet Network Ports - Rear Panel
1. Connect a Category 5 cable from your network switch or hub to Ethernet Port 0 (NET0) on the rear of the chassis.
NET0 is the farthest left port in the 4-port network cluster in FIGURE 5-5.
2. Connect Category 5 cables from your network switch or hub to the remaining Ethernet ports (NET1, NET2, NET3), as needed.
Note - The LEDs located above each NET port are Link/Activity (left) and Speed (right) indicators for each port. |
To Connect AC Power Cables to the Server |
Powering on the system for the first time requires special preparation and procedures. For example, if you have not prepared a display before connecting the AC power cable, system messages might be lost.
Caution - Finish the hardware procedures in this chapter, but do not attach the AC power cable yet. |
Powering on the system for the first time requires special preparation and procedures. For example, if you have not prepared a display before connecting the AC power cable, system messages could be missed.
Caution - The server goes into Standby mode and the service processor initializes as soon as the AC power cable is connected to the power source. |
Go to Powering On the System for the First Time for instructions on connecting the server to AC power.
This section provides DC power cabling and requirements information.
TABLE 5-3 lists DC power source requirements for each power supply in the Sun Netra T5220 server, and TABLE 5-4 lists DC power source requirements for the server as a whole.
The server must meet the following:
The server must meet the following:
Note - Depending on the DC power source, the -48V (negative terminal) might be marked with a minus (-) symbol, and the -48V Return (positive terminal) might be marked with a positive (+) symbol. |
When attaching DC cables, keep the following requirement in mind:
Note - Overcurrent protection devices must meet applicable national and local electrical safety codes and be approved for the intended application. |
To Assemble the DC Input Power Cable |
1. Identify the parts that you will use to assemble the DC input power cable (FIGURE 5-6).
The following DC connection parts are required to assemble one or more DC power input cables. These cables connect the -48V DC input source(s) to the power supply units.
FIGURE 5-6 DC Connection Parts
2. Turn off power from the DC power source through the circuit breakers.
Caution - Do notproceed with these instructions until you have turned off the power from the DC power source through the circuit breakers. |
3. Get a DC input plug from the ship kit.
4. Locate the three wires coming from the DC power source that will be used in the connection to your unit:
Note - Depending on the DC power source, the -48V (negative terminal) might be marked with a minus (-) symbol, and the -48V Return (positive terminal) might be marked with a positive (+) symbol. |
5. Strip 5/16 inches (8 mm) of insulation from each of the wires coming from the DC power source.
Do not strip more than 5/16 inches (8 mm) from each wire. Doing so leaves uninsulated wire exposed from the DC connector after the assembly is complete.
FIGURE 5-7 Stripping the Insulation From the Wire
6. Open the cage clamp for this section of the DC input plug by taking one of the following actions:
FIGURE 5-8 Opening the DC Input Plug Cage Clamp Using the Cage Clamp Operating Lever
FIGURE 5-9 Opening the Cage Clamp Using a Screwdriver
7. Feed the exposed section of the appropriate wire into the rectangular plug hole in the DC input plug.
FIGURE 5-10 shows which wires should be inserted into each hole in the DC input plug.
FIGURE 5-10 Assembling the DC Input Power Cable
8. Repeat Step 6 and Step 7 for the other two wires to complete the assembly of the DC input power cable.
9. Repeat Step 4 through Step 8 to create as many DC input power cables as you need for your unit.
You need two DC input power cables for each of the power supplies.
If you need to remove a wire from the DC input plug, insert the cage clamp operating lever or a small screwdriver into the slot directly above the wire and press down (FIGURE 5-8 and FIGURE 5-9). Pull the wire from the DC input plug.
