Powering a Server On and Off |
This chapter provides instructions for powering a Netra CT server on and off, and it contains the following topics.
Note - You can power a Netra CT server on and off through the alarm card using software commands. Refer to the Netra CT Server System Administration Manual for information. |
One way to power your server on and off is to log in to the server either remotely, where you would log in to the Netra CT server as superuser through another server on the network, or directly, where you would connect a terminal console directly to your Netra CT server. A terminal console can be an ASCII terminal, workstation, or PC laptop.
For a direct login, the connection you use varies depending on the Netra CT server model you have, the type of terminal console you are using, and the board that you are connecting to:
To Connect Using an ASCII Terminal |
1. Get the appropriate cable and adapter, then make the necessary connections.
You might need one or more cables and adapters to connect the ASCII terminal to the server. The cables and adapters you need vary, depending on the model server you have and the board that you are connecting to.

2. Access the Set Up Menu of the ASCII terminal and bring up the serial communications section.
3. Set up the serial port communications parameters.
The default settings should match the values reported on the host serial port.
Verify that communication is established to the server and the keyboard/display of the ASCII terminal.
To Use a Solaris Workstation |
1. Obtain the cable and adapter and make the necessary connections.
You might need one or more cables and adapters to connect a Solaris workstation to a server. The cables and adapters you need vary, depending on the model server you have and the board that you are connecting to.

2. Check the /etc/remote file for the appropriate line.
To connect to the TTY A or COM 1 port on the workstation, check for:
3. Type tip hardwire at the prompt.
The word connected is displayed as the response.
To disconnect the tip window, type ~. (tilde period) at the prompt.
To Connect Using a PC Laptop |
1. Obtain the cable and adapter, then make the necessary connections.
You might need one or more cables and adapters to connect a PC laptop to a server. The cables and adapters you need vary, depending on the model server you have and the board that you are connecting to.

2. Set the following connection parameters:
To Power On a Server |
1. Verify that the power supply locking mechanisms on the server you are about to power on are in the locked (), or down, positions (FIGURE 7-1).
Make sure you lock both power supplies if you are powering on a Netra CT 810 server.
When the power supply locking mechanism is locked, the green LED on the power supply flashes, indicating that the power supply is powered on; however, the server is not powered on yet. The PDU LEDs on the system status panel should be as follows:
These states indicate that the power supply locking mechanisms are in the locked (down) position, and that the power distribution units are receiving power and functioning properly.
2. Locate the system status panel.
The location of the system status panel in a Netra CT 810 server and Netra CT 410 server are illustrated in FIGURE 7-2.
3. Locate the system power button on the system status panel, then press the system power button to power on the server.
FIGURE 7-3 shows the system power button location for a Netra CT 810 server, and FIGURE 7-4 shows the system power button location for a Netra CT 410 server.
When you first power on the Netra CT server, some or all of the green Power LEDs on the system status panel flash on and off for several moments.
4. Verify that the system power LED on the system status panel is on, indicating that the system is completely powered on.
FIGURE 7-3 shows the system power LED location for a Netra CT 810 server, and FIGURE 7-4 shows the system power LED location for a Netra CT 410 server.
5. Verify that the green power () LEDs on the power supplies are on, indicating that they are powered on and functioning properly.
6. If you have a Netra CT 410 server, connect an external DVD drive to your server.
See Appendix A for information.
7. Insert the Solaris OS DVD into the DVD drive.
See Connecting a Terminal Console to a Server for instructions on connecting a terminal to your server, if necessary.
9. Boot up the server through the DVD drive.
You can power off the Netra CT server one of three ways, depending on the terminal hookup and the state of the host CPU board:
To Perform a Graceful Software Power-Down |
1. In preparation for bringing down the operating system and powering down the server, ensure that all significant application activity is stopped on the server.
2. Log in to your server as root.
See Connecting a Terminal Console to a Server for information.
3. Determine if you are at the OpenBoot (ok) prompt.
When the server is finished shutting down, the ok prompt is displayed.
5. Go to the front of the Netra CT server and locate the power supply units.
6. Determine if the green power () LED on the power supply units are blinking.
7. If you want to completely power off the Netra CT server, push the purple power supply unit locking mechanisms up into the unlocked () position (see FIGURE 7-1).
Note - You must unlock the locking mechanism on both power supply units on the Netra CT 810 server to completely power off the server. |
The green power () LEDs on the power supply units go off (unlit), indicating that the system is now completely powered off.
To Perform a Graceful Hardware Power-Down |
1. In preparation for bringing down the operating system and powering off the server, ensure that all significant application activity is stopped on the server.
2. Go to the front of the Netra CT server and locate the system status panel.
The locations of the system status panels in the Netra CT 810 server and Netra CT 410 server are illustrated in FIGURE 7-2.
3. Locate the system power button on the system status panel.
FIGURE 7-3 shows the system power button location for a Netra CT 810 server, and FIGURE 7-4 shows the system power button location for a Netra CT 410 server.
4. Press the system power button and release it to go through a graceful hardware power-down.
This action starts the orderly power-down sequence in such a manner that no persistent OS data structures are corrupted. Applications in service might be abnormally terminated and no further services are invoked by the host CPU. The system power LED blinks for several seconds, then goes off.
5. Wait for several moments, then verify that the green power () LEDs on the power supply units are blinking, indicating that the system is in the standby mode.
FIGURE 7-3 shows the system power LED location for a Netra CT 810 server, and FIGURE 7-4 shows the system power LED location for a Netra CT 410 server.
6. If you want to completely power off the Netra CT server, push the purple power supply unit locking mechanisms up into the unlocked () position (see FIGURE 7-1).
Note - You must unlock the locking mechanism on both power supply units on the Netra CT 810 server to completely power off the server. |
The green power () LEDs on the power supply units go off (unlit), indicating that the system is now completely powered off.
