3 Servicing CRUs That Do Not Require System Power Off

This chapter describes how to remove and replace the hot-swappable components in Oracle Database Appliance. Hot-swappable means that these components can be replaced with the system powered on.

Note:

Hot-swappable components can also be replaced with the system powered off. If you choose this method, first power off the system as described in Chapter 2, Preparing Oracle Database Appliance for Service.

The following topics are covered:

Oracle Database Appliance X3-2/X4-2/X5-2 Server Node Hot-Swappable Components

This section describes replacing hot-swappable components for the Oracle Database Appliance X3-2, Oracle Database Appliance X4-2, and Oracle Database Appliance X5-2 for service. If you have Oracle Database Appliance (original version), go to Oracle Database Appliance (Original Version) Hot-Swappable Components.

Hot-swappable components are those that can be removed and installed while the system and the server nodes are running without requiring any administrative tasks. These are designated as Customer Replaceable Units (CRUs).

Refer to the following table for hot-swap component instructions for your appliance.

Servicing Fan Modules (CRU)

Each Oracle Database Appliance (original version) server node contains two fan modules. Each fan module contains a single, dual-motor, 80 mm, counter-rotating fan assembly that contains two fans. Each fan module is hot-swappable. For specific information about fan status LEDs, see Server Node Fan Indicators.

When a server node is removed from the system, the fans provide sufficient cooling for all 24 front disks and the server node. A door automatically closes off the vacant server node slot to ensure proper cooling. When the server node is replaced, its two fans also cool the 24 front disks and provide cooling to the second server node.

Caution:

Equipment damage. If a fan module fails, replace it as soon as possible.

The following topics are covered in this section:

Detecting a Fan Module Failure

The following LEDs are lit when a fan module fault is detected:

Front and rear Service Required LEDs located on each server node
REAR HDD/PS/FAN LED located on the front of each server node
Fan Fault Status LED located on the faulty fan module

The system over-temperature LED for a server node might light if a fan fault causes an increase in server node operating temperature. See Server Node Status Indicators for more information about server node LEDs.
