RTM overview
The ATCA-5400 RTM is an optional compatible rear transition module for the ATCA-4500 CPM
front module that supplies the CPM with additional data storage and connectivity options.
The RTM has an on-board SAS/SATA controller and can host an optional SAS hard disk drive
(HDD). The controller can access an HDD AMC if one is installed on the CPM. The RTM also
includes two rear panel SAS ports to allow cable connections to additional hard disk drives, such
as hard disk drives accessible from another RTM. The SAS/SATA controller supports RAID
(redundant array of inexpensive disks), including RAID 0 (striping) and RAID 1 (mirroring)
configurations.
For instructions on installing a hard disk drive, see Installing a hard disk drive on page 12. For
instructions on configuring a RAID, see Chapter 3, Configuring a Redundant Disk Array, on
page 15.
The RTM has two 1-gigabit Ethernet SFP sockets on its face plate that can facilitate external
connections through the RTM to the CPM. These rear Ethernet ports are usable when the
Ethernet controller on the CPM is configured to route the connections to the RTM. On the
ATCA-4500 CPM, a BIOS menu setting determines whether these connections are routed to the
CPM front panel or to the RTM. For instructions on installing SFP transceivers in the SFP sockets,
see Installing SFPs on page 11.
The RS-232 serial port on the RTM provides a management interface to the CPM. The RTM also
includes a USB 2.0 port that connects to the CPM.
A module management controller (MMC) provides intelligent management of the RTM
hardware, including its managed sensors. The MMC responds to reset signals from the CPM as
well as IPMI commands.

2 INSTALLING FRUS
Installing SFPs
The RTM has sockets that accept SFP (small form-factor pluggable) transceiver modules. If SFP
transceivers are installed, they can provide external connections to the Ethernet interfaces. The
sockets are located on the face plate of the RTM, as shown in Figure 4 on page 19.
SFP transceivers can be installed on the RTM at any time.
Configuration recommendations
The RTM supports up to two SFP transceivers, with filler plugs installed in unused sockets. For a
list of tested and qualified transceivers, see the Promentum Component Compatibility Report in
the AdvancedTCA downloads section of the RadiSys Web site at www.radisys.com/downloads.
Standard RTM configurations come with SFP filler plugs installed to protect the internal
components of the RTM.
Transceiver installation
The illustration shows the correct orientation for
inserting an SFP transceiver. The transceiver
may vary in appearance, but the same insertion
guidelines should be used.
1. Obey the ESD procedures in Electrostatic
discharge on page 7 and make sure you
are adequately grounded.
2. Remove the RTM and the transceivers from
their antistatic bags.
3. On the RTM face plate, remove the filler
plugs from the sockets where the
transceivers will be installed. For sockets
not being used, keep the filler plugs in
place. The plugs protect the sockets, control
airflow, and prevent electromagnetic
interference.
4. Make sure the latch on the cable end of the
transceiver is closed. This makes the SFP
snap into position when it is inserted into
the socket.

5. Hold the transceiver near the cable end and turn the connector side to the correct position
depending on the RTM orientation:
If the RTM is vertical, turn the transceiver so the connector side is on the right.
If the RTM is horizontal, turn the transceiver so the connector side is down.
6. Insert the connector end of the transceiver into the socket.
7. Once inserted into the socket, carefully slide the transceiver until its connector is fully seated
and the SFP snaps into position.
8. Repeat the previous steps for each transceiver being installed.
9. For transceivers with cable plugs installed on their cable end, keep the plugs in place until it
is time to connect cables to the transceivers. The cable plugs protect the internal
components of the transceivers from dust and foreign contaminants.
Note: If an SFP needs to be removed, open the latch and pull the SFP out of the socket.
Filler plug installation
If the SFP transceivers are removed, install either replacement transceivers or filler plugs to
protect the sockets, to control airflow, and to prevent electromagnetic interference.
Installing a hard disk drive
RadiSys ships the RTM without a hard disk drive (HDD) installed. A separate HDD can be
ordered from RadiSys and installed onto the RTM prior to installing the RTM into the shelf. For
information on suitable hard disk drives, see the Promentum Component Compatibility Report
in the AdvancedTCA downloads section of the Web site at www.radisys.com/downloads.
The RTM ships with a sled for sliding the HDD into the correct mounting position on the RTM
(see Figure 2 on page 13). To install the HDD on the RTM, first attach the HDD to the drive sled
with the provided screws and then mount the sled and HDD onto the RTM. The following
sections explain the installation procedure.
Before starting: Get a medium-size Phillips screwdriver and a suitable HDD.
Updating the drive information record
If you are installing a new hard disk drive or replacing an existing one, follow these steps to
ensure that the drive information record for the MMC has the correct hard disk drive type when
the RTM resets after it is inserted into the chassis.
1. Insert the RTM into the rear of the chassis in the slot corresponding to the associated front
module CPM.
2. Update the drive information record in the FRU data with data about the new hard disk drive
to be installed. Enter this rmcpta command:
setdriveinfo
3. Remove the RTM from the chassis and proceed to Attaching the drive sled to the HDD on
page 13.

Attaching the drive sled to the HDD
1. Obey the ESD procedures in Electrostatic discharge on page 7 and make sure you are
adequately grounded.
2. Place the drive sled on a static-free surface with the retaining screw (screw head up) at the
left. See Figure 2.
3. Place the hard disk drive (HDD) component side down on the drive sled with the HDD
SAS/SATA connector at the right.
4. Hold the HDD and drive sled together and turn them upside down to access the screw
holes.
5. Screw the four supplied M3 screws through the sled holes shown in Figure 2 and into the
corresponding holes on the HDD.
6. Turn the HDD and drive sled right-side up so the retaining screw head faces up.

Mounting the hard disk drive and sled onto the RTM
1. Align the four sled keyhole screws over the RTM keyholes and simultaneously guide all four
screws down into the keyholes.
2. Slide the sled along the keyhole slot toward the RTM face plate and then toward the RTM
SAS/SATA connector. See Figure 2 on page 13. The hard disk drive SAS connector mates
with the RTM SAS/SATA connector.
3. Secure the sled to the RTM by tightening the retaining screw with a screwdriver.
Inserting the RTM into the chassis
After the hard disk drive is installed, insert the RTM into the chassis. The MMC will report the
correct drive type because it was previously set in Updating the drive information record on
page 12.

3 CONFIGURING A REDUNDANT DISK ARRAY
This chapter explains the RTM’s support for RAID (redundant array of inexpensive disks) and
how to configure a RAID from the available hard disk drives. Hard disk drive arrays can be
configured in the SAS BIOS, which is the BIOS for the SAS/SATA controller. Some hard disk
drives must be connected to the RTM with cables before you can include them in an array.
Supported RAID configurations
The RTM’s SAS/SATA controller supports these RAID levels and configurations:
RAID 1 integrated mirroring (IM), which provides redundancy. Two hard disk drives (a
primary and secondary) must be identified to be used as exact copies. Up to two hot spare
hard disk drives can be included in case one of the copied hard disk drives fails. In case of
failure, the contents of the remaining good hard disk drive can be copied to a hot spare,
which also gets a copy of all new data. The available hard disk drive capacity is the same as
the smallest hard disk drive or spare in the array.
RAID 1 integrated mirroring enhanced (IME), which provides striping and one copy of
each stripe for redundancy. At least 3 hard disk drives must be used, with a maximum of 8
copies. Up to two hot spare hard disk drives can be included in case one of the participating
hard disk drives fails. The available hard disk drive capacity is the smallest disk capacity in
the array multiplied by the number of hard disk drives in the array, and then divided by two.
This is due to the mirrored stripes used in the IME array.
RAID 0 integrated striping (IS), which improves performance. At least 3 hard disk drives
must be identified to participate, with a maximum of 10 hard disk drives. The available hard
disk drive capacity is the capacity of the smallest hard disk drive in the array multiplied by
the number of hard disk drives in the array.
The SAS/SATA controller supports multiple arrays at once, including arrays of different types, as
long as the number of available hard disk drives is sufficient to support the arrays. For additional
information on the supported RAID options, see the Integrated RAID for SAS User’s Guide from
LSI Logic Corporation.

Configuring a Redundant Disk Array
16
Preparing hard disk drives to participate in an array
Table 1 identifies the locations of hard disk drives that can be used by the RTM SAS/SATA
controller in an array. It also shows the physical SAS connection that must be present before you
can include the hard disk drive in an array through a SAS BIOS configuration.
Tip: Before configuring an array in the SAS BIOS, you may want to make a copy of any existing
data on the hard disk drives. All existing data is deleted from the hard disk drives that participate
in an IS array. For a hard disk drive that will act as the primary hard disk drive in an IM or IME
array, the SAS BIOS configuration gives you the option to keep existing data on the hard disk
drive. For other hard disk drives in an IM or IME array, any existing data is deleted.

4. Select the RAID Properties option and press Enter.
5. Select the option for the type of RAID to create:
A. Select Create IM Volume to set up a RAID 1 mirroring volume.
Select two RAID hard disk drives to act as the primary and secondary mirror hard disk
drives, and optionally up to two hot spares in case the primary or secondary fails.
The first hard disk drive you select is the primary hard disk drive, which allows the option
to keep existing data. Data on a secondary hard disk drive is deleted.
B. Select Create IME Volume to set up a RAID 1E volume for mirroring with
enhancements.
Select at least three RAID hard disk drives to participate in the array, and up to two hot
spares in case a participating hard disk drive fails.
The first hard disk drive you select is the primary hard disk drive, which allows the option
to keep existing data. Data on each secondary hard disk drive is deleted.
C. Select Create IS Volume to set up a RAID 0 striping volume.
Select at least 3 hard disk drives to include in the array, with a maximum of 10. Data on
each hard disk drive in a striping array is deleted.
Note: When two pairs of RTMs and CPMs are cabled together, the hard disk drives are
identified in the SAS BIOS screens by slot number instead of the SAS/SATA port number.
The identification is as follows:
Slot 0: Local RTM hard disk drive (on the RTM controlling the RAID)
Slot 1: Local HDD AMC hard disk drive
Slot 2: Remote RTM hard disk drive (when a custom crossover cable is used)
Slot 3: Remote HDD AMC hard disk drive (when a custom crossover cable is used)
When a standard crossover cable is used, slots 1 and 2 remain the same but slots 3 and
4 identify an external hard disk drive array.
The slot numbers correspond to the SAS/SATA controller port numbers in Figure 3 on
page 17.
6. Complete the array configuration by pressing C.
7. Save the changes when prompted.
Note: When one array has been configured, use the Manage Array option to view, delete, or
modify the hot spares in the array. When multiple arrays have been configured, use the View
Existing Array option to select and manage an array.
For additional details about using the SAS BIOS screens to create an array, see the Integrated
RAID for SAS User’s Guide from LSI Logic Corporation.
