The IBM TotalStorage™is designed for workgroups, departments, and solution
providers that have storage area network requirements across heterogeneous
Microsoft
The Model 200 is a tower unit that requires only power and network connections for
setup. For the Model 200, a conversion kit is available to convert the tower for rack
mounting. The Model 225 can be mounted in a 5U rack drawer. The Model 225 has
external SCSI connections for up to three 5194-EXU storage units for a total rack
requirement of 14U.
As an appliance with redundant power supplies, the appliance is shipped with three
power cords. It does not come with a mouse, keyboard, or monitor. The appliance
is already configured; aside from initial configuration to determine the IP address,
you do not need to configure hardware or install for the base model configurations.
The Model 200 requires two connections: power and network.

Installing optional features
The appliance has several optional features available.
Installing a 5194-EXU storage unit
The Model 225 includes the option of installing up to three additional 5194-EXU
storage units, or Model EXUs. 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 5194-EXU storage unit to a Model 200 because ServeRAID-4L has
only one channel connector.

Figure 3. ServeRAID-4H channel connector locations
Important: When adding 5194-EXU storage units to the Model 225, 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.
Chapter 2. Installation procedures 11
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:
v Throw or immerse into water
v Heat to more than 100°C (212°F)
v 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 5194-EXU 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 on page 11 for the channel connector locations.
2. Connect the other end of the SCSI cable to the 5194-EXU storage unit. For
detailed installation and cabling instructions for the 5194-EXU storage unit, refer
to the IBM TotalStorage Network Attached Storage 5194-EXU Storage Unit
Installation and User’s Guide.
Installing a hot-swap hard drive
You can install up to three hot-swap drives in the Model 200. (The Model 225
already has the maximum number of hot-swap drives allowed without adding a
5194-EXU storage unit.)
Each hot-swap drive that you plan to install must have a hot-swap-drive tray
attached. The drive must have a single connector attachment (SCA) connector.
Hot-swap-drive trays come with the hot-swap drives.
v Models 200 and 225 support six slim (1-inch) 3.5-inch hot-swap hard disk drives
in the hot-swap bays. The Model EXU supports 14 slim (1-inch) 3.5-inch
hot-swap hard disk drives.
v The hot-swap bays connect to the planar. The planar is the printed circuit board
behind the bay.
v The planar controls the SCSI IDs for the hot swap drives.

or replace hot-swap power supplies or hot-swap hard drives.
v Back up all important data before you make changes to hard drives.
v 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” on page 76.
To install a hard disk drive in a hot-swap drive bay:
1. Review the safety precautions in “Safety precautions” on page ix.
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:
a. Ensure the tray handle is open (that is, perpendicular to the drive).
b. Align the rails on the drive assembly with the guide rails in the drive bay.
c. Gently push the drive assembly into the bay until the drive connects to the
planar.
d. 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 :
v When the amber LED is on continuously, the drive has failed.
v When the green LED flashes slowly (one flash per second), the drive is being
rebuilt.
v When the green LED flashes rapidly (three flashes per second), the controller
is identifying the drive.

Installing memory modules (DIMMs)
You can install additional memory modules to the Model 200, which includes one
256-MB DIMM.
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” on page 15).
3. Install the memory module (see “Adding the memory module” on page 17).
4. Replace the cover (see “Replacing the cover” on page 19).
Preparing to install a memory module
Read these notes before installing a memory module.
Note:
v Become familiar with the safety and handling guidelines specified under
“Handling electrostatic discharge-sensitive devices” on page 76.
v The blue color on components and labels inside your Models 200 and 225
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.
v Make sure that you have an adequate number of properly grounded
electrical outlets for Models 200 and 225 and any other options that you
intend to install.
v Have a small, flat-blade screwdriver available.
v Before you begin installing components, read the safety information found
in “Translated safety notices” on page 77.
v For translations of the safety notices that are included in this guide, refer
to Safety Information.

System reliability considerations: To help ensure proper cooling and system
reliability, make sure that:
v Each of the drive bays has either a drive or a filler panel installed.
v The cover is in place during normal operations, or is removed for no longer than
30 minutes while the appliance is operating.
Note: The front door (Model 200) can be removed permanently without affecting
system reliability.
v There is space around the appliance to allow the appliance cooling system to
work properly.
– For Model 200, leave about 127 mm (5 in.) of space around the front and rear
of the appliance.
– For Model 225, refer to the documentation that comes with the rack.
v A removed hot-swap drive is replaced within 2 minutes of removal.
v Cables for optional adapters are routed according to the instructions provided
with the adapters.
v A failed fan is replaced within 48 hours.
