7.1 SPARCcluster 1000 High Availability Server

For these procedures, the administration workstation may need to be installed (see the caution above). Refer to Chapter 9 Section 9.2.7.1, "Connecting the Administration Workstation" and to Table 9-3 for this procedure.

7.1.1 Powering Off a Server (Node)

---

Note - It is understood that the server in question is in the process of hardware installation. This system has no users nor data files to be concerned with. If this is not true, halt the system using the procedure found in the SPARCcluster High Availability Software Administration Guide, Sun part number 802-3511.

---

1. Turn the front panel key switch to (the standby position).

   This switch is behind the top vented panel. See Figure 7-1.

Figure 7-1

2. Turn the AC distribution unit power switch to OFF.

   The unit is at the rear of the cabinet. See Figure 7-2.

---

Caution - Turn off the power at the AC distribution unit power switch on the rear of the system before attempting to access the system cabinet.

---

Warning - Some users may elect to power internal cabinet components, like SPARCstorage arrays, the terminal concentrator, etc., from an external power source (a power circuit other than from the cabinet internal AC power distribution unit). These components, if plugged into an external power source will remain powered even after the cabinet AC distribution unit is turned OFF. Examine the system to verify that no component is externally powered before proceeding. If any component is externally powered, turn the component OFF using the ON/OFF switch at the rear of the component in question. Failure to turn off externally powered components poses a risk of equipment damage and/or personnel hazard from electrical shock.

7.1.2 Powering On a Server (Node)

1. Begin with a safety inspection.

   a. Ensure the AC power switch ON the cabinet rear is off. b. Verify the power cord is plugged into the correct facilities outlet.

2. Ensure the LOCAL/OFF/REMOTE switch is in the REMOTE position.

   Refer to Figure 7-2.

3. Ensure the key switch is in the (standby position).

   See Figure 7-3.

4. Turn the AC power switch on the rear of the cabinet to ON.

   Refer to Figure 7-2.

5. Turn the key switch to (the power-on position).

   See Figure 7-1. You will hear the fans spinning up.

---

Caution - Never move the system cabinet or the expansion cabinets when system power is on. Excessive movement can cause catastrophic disk drive failure. Always power the server OFF before moving cabinets.

7.2 SPARCcluster 2000 High Availability Server

For these procedures, the administration workstation may need to be installed (see the caution at the beginning of this chapter). Refer to Chapter 10 Section 10.2.8.1, "Connecting the Administration workstation" and to Table 10-3 for this procedure.

7.2.1 Powering Off a Server (Node)

Note - It is understood that the server in question is in the process of hardware installation. This system has no users nor data files to be concerned with. If this is not true, halt the system using the procedure found in the SPARCcluster High Availability Software Administration Guide, Sun part number 802-3511.

1. Turn the front panel key switch to (the standby position).

   See Figure 7-3.

2. Turn the AC distribution unit power switch to OFF.

   The unit is at the rear of the cabinet. See Figure 7-4.

---

Caution - Turn off the power at the AC distribution unit power switch on the rear of the system before attempting to access the system cabinet.

7.3 Powering On the Server/Storage Chassis

For proper power-on procedures for each chassis installed in the cabinet, refer to the appropriate installation and/or service manual for that chassis.

7.4 Reading POST Messages and Boot Messages

For each server system installed in the expansion cabinet, refer to the appropriate installation and/or service manual. Read the section covering Power-On Self-Test (POST) messages and Boot messages to interpret messages for that server.

Likewise, for each storage chassis installed in the expansion cabinet, refer to the installation and/or service manual for the server acting as node to that storage chassis. Messages presented by this server will encompass power-on and boot behavior of the storage chassis in question. In addition, refer to the installation and/or service manual for the storage chassis itself for any additional clarification.
