Preface About this manual This manual describes the ATCA‐5400, a rear transition module (RTM) that is fully compliant with AdvancedTCA® (PICMG 3.0 Advanced Telecommunications Computing Architecture R3.0). The RTM is designed to mate with a compatible front module, such as the ATCA‐4500, ATCA‐4550, and ATCA‐4555 Compute Processing Module, in high availability (HA) Radisys platform systems. Use this manual as a reference for the operation and maintenance of the RTM.

Chapter 1 Product Overview This chapter briefly describes the ATCA‐5400 RTM. RTM overview The ATCA‐5400 RTM is an optional compatible rear transition module for the ATCA‐4500, ATCA‐4550, and ATCA‐4555 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.

Chapter 2 Installing FRUs Installing SFPs The RTM has sockets that accept SFP (small form‐factor pluggable) transceiver modules. These modules provide external connections to the Ethernet interfaces, and they can be installed on the RTM at any time. The sockets are located on the face plate of the RTM, as shown in Figure 4 on page 19. Configuration recommendations The RTM supports up to two SFP transceivers.
2 Installing FRUs 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.
2 Installing FRUs Figure 2. HDD installation Hard disk drive (HDD) SAS/SATA connector Retaining screw Drive sled Mounting screw Keyhole screw Keyhole SAS/SATA connector 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.
2 Installing FRUs Updating the drive information record If you are installing a new hard disk drive or replacing an existing one, use the rmcpta command to ensure 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. Important: To ensure compatibility with the commands in this procedure, use the version of rmcpta that is provided with the latest Radisys software release. 1.
Chapter 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.
Configuring a Redundant Disk Array 3 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. Table 1.

Configuring a Redundant Disk Array 3 Updating the drive information record to enable the secondary ports Use the rmcpta command to ensure the drive information record for the MMC has the correct hard disk drive type when the RTM is powered up in the chassis. Important: To ensure compatibility with the commands in this procedure, use the version of rmcpta that is provided with the latest Radisys software release. 1. Invoke rmcpta, specifying the Shelf Manager IP address: rmcpta ‐h 2.
Configuring a Redundant Disk Array 3 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.
Chapter 4 LEDs and External Interfaces Face plate interfaces The external interfaces on the RTM face plate include a USB port, two external SAS ports, an RS‐232 serial port, two SFP sockets, and a reset button. Figure 4 shows the location of the interfaces on the RTM face plate. Figure 4.

Face plate connectors Connector Purpose and usage Cable type USB port Provides USB 2.0 access to the CPM. USB type A cable. SAS connector (two) Extends disk arrays by connecting external hard disks to the RTM. The RTM’s SAS/SATA controller can include external disks in a RAID configuration.

4 LEDs and External Interfaces Zone 3 interface Two Zone 3 connectors (P30 and P31) provide the following connections to the RTM: • Two SAS lanes to provide access to a SAS hard disk drive on the CPM, connected to: • AMC Port 2 • AMC Port 3 • x4 PCIe Gen2 connection from the CPM (which serves the RTM’s PCIe Gen1 devices) • Two 1 GbE SerDes lanes from the CPM Ethernet controller • One reset input signal to pass a PCI reset from the CPM to the SAS/SATA controller • Reset button state passed from the RTM thro

Chapter 5 Components and Subsystems SAS/SATA controller The RTM includes an LSI Logic LSISAS1064E, which is a Serial Attached SCSI/Serial Advanced Technology Attachment (SAS/SATA) controller. The controller has four SAS/SATA ports that operate at 3 Gbps and connect to these components: • The RTM’s optional hard disk drive • The two rear SAS ports • An AMC installed in the CPM The controller also supports a PCI Express interface, which can be used as a single x1 or x4 lane to connect the RTM to the CPM.
5 Components and Subsystems Hardware management The RTM includes a module management controller (MMC), which enables the RTM to provide local IPMC functions for self‐control and monitoring. The ability to provide these functions makes the RTM an intelligent FRU. It connects to the CPM’s local IPMB and reports events from its managed sensors to the CPM, which sends them to the Shelf Manager. The MMC subsystem on the RTM consists of a ATmega128 microcontroller and non‐volatile (NV) memory.
Components and Subsystems 5 Hot swap The RTM can be hot swapped, and functions as the AMC module does during the hot‐swap process. The hot‐swap latch status is read by the MMC. Hot swapping means that the RTM can be removed or inserted without shutting down any other part of the CPM or the platform.
5 Components and Subsystems Upgradeable components Table 6 summarizes the programmable devices on the RTM and the content that can be upgraded. Table 6.
Appendix A Specifications Environmental specifications The RTM is designed to meet the following environmental specifications. The operating environment must provide sufficient airflow across the module to keep it within its temperature specification. Table 7.

IPMI Commands and Managed Sensors B Types of sensors The RTM implements the following types of sensors. • Discrete — A discrete sensor can represent up to16 states. The sensor is coded as a 16‐bit value with one bit true and the remaining bits false. • Digital — A digital sensor has two possible states, only one of which can be active at any given time. For example, a digital sensor monitoring the power may indicate whether the power is good (within an acceptable range) or not.
