Installation Guide

Installing optional features

The appliance has several optional features available.

Installing a storage unit

The Model 200 includes the option of installing up to three additional storage units, or Model EXPs. The internal hot-swap SCSI disks are connected internally to Channel 1 for both the ServeRAID-4H and ServeRAID-4L adapters. You cannot attach a storage unit to a Model 100 because ServeRAID-4L has only one channel connector.

Figure 3. ServeRAID-4H channel connector locations

Important:

When adding storage units to the Model 200, connect the first additional storage unit to Channel 2, the second to Channel 3, and so forth.

Notes:

1. The ServeRAID-4L and ServeRAID-4H adapters do not support configurations that use both the internal and external connectors on the same channel concurrently. For example, you cannot use both external Channel 1 and internal Channel 1.

2. The battery-backup cache protects the data stored in the ServeRAID cache memory during a power outage or failure when using the write-back mode.

3. The ServeRAID-4H controller uses the module (part number 38L3386) containing a lithium battery.

Statement 2

Caution:
When replacing the lithium battery, use only IBM Part Number 33F8354 or an equivalent type battery recommended by the manufacturer. If your system has a module containing a lithium battery, replace it only with the same module type made by the same manufacturer. The battery contains lithium and can explode if not properly used, handled, or disposed of.

Do not:

• Throw or immerse into water
• Heat to more than 100°C (212°F)
• Repair or disassemble

Dispose of the battery as required by local ordinances or regulations.

Note:

For translations of the safety notices that are included in this guide, refer to Safety Information.

To connect storage units to an external channel connector on the ServeRAID-4H controller:

1. Connect one end of a 68-pin very high density connector interface (VHDCI) SCSI cable to an external channel connector on the ServeRAID-4H adapter.

   Note:

   See Figure 3 for the channel connector locations.

2. Connect the other end of the SCSI cable to the storage unit. For detailed installation and cabling instructions for the storage unit, refer to the IBM TotalStorage IP Storage 200i Storage Unit Installation Guide.

Installing a hot-swap hard drive

Figure 4. Installing a hot-swap hard drive

Attention:

• To maintain proper system cooling, do not operate the appliance for more than two minutes without either a drive or a filler panel installed for each bay.
• You do not need to switch off the Models 100 and 200 or remove covers to install or replace hot-swap power supplies or hot-swap hard drives.
• Back up all important data before you make changes to hard drives.
• When you handle electrostatic discharge-sensitive devices (ESDs), take precautions to avoid damage from static electricity. For details on handling these devices, refer to Handling electrostatic discharge-sensitive devices.

To install a hard disk drive in a hot-swap drive bay:

1. Review the safety precautions in "Safety precautions".
2. Remove the filler panel from one of the empty hot-swap bays by inserting your finger into the depression at the left side of the filler panel and pulling it away from the appliance.
3. Install the hard disk drive in the hot-swap bay:
   1. Ensure the tray handle is open (that is, perpendicular to the drive).
   2. Align the rails on the drive assembly with the guide rails in the drive bay.
   3. Gently push the drive assembly into the bay until the drive connects to the planar.
   4. Push the tray handle toward the closed position until it locks the drive in place.
4. Check the hard disk drive status indicators to verify that the hard disk drives are operating properly :
   • When the amber LED is on continuously, the drive has failed.
   • When the green LED flashes slowly (one flash per second), the drive is being rebuilt.
   • When the green LED flashes rapidly (three flashes per second), the controller is identifying the drive.

Installing memory modules (DIMMs)

You can increase the amount of memory in your appliance by installing options called memory-module kits. Each kit contains one industry-standard, dual-inline memory module (DIMM). Your appliance uses a noninterleaved memory configuration.

Your appliance comes with one or more dual inline memory modules (DIMM) installed on the system board in the DIMM connectors.

This section describes how to replace a memory module. It consists of four steps:

1. Prepare to install the memory module (see Preparing to install a memory module).
2. Remove the cover (see Removing the cover).
3. Install the memory module (see Adding the memory module).
4. Replace the cover (see Replacing the cover).

Preparing to install a memory module

Read these notes before installing a memory module.

Note:

• Become familiar with the safety and handling guidelines specified under Handling electrostatic discharge-sensitive devices.
• The blue color on components and labels inside your Models 100 and 200 identifies touch points where a component can be gripped, a latch moved, and so on. The only exception to this is the power supplies, which are orange.
• Make sure that you have an adequate number of properly grounded electrical outlets for Models 100 and 200 and any other options that you intend to install.
• Have a small, flat-blade screwdriver available.
• Before you begin installing components, read the safety information found in Translated safety notices.
• For translations of the safety notices that are included in this guide, refer to Safety Information.
