specification for additional details.
1.6 Interfacing with the Environment
1.6.1 RTM (rear transition module)
The RTM8050 is a single slot (6HP) AdvancedTCA Rear Transition Module. This module provides additional
connectivity for AT8050 CPU front board.

• Compliant to SAS-1.1 Revision 10 / SFF-8470
• SAS signal integrity guarantee over a four meters cable
1.6.1.2 Serial Port Feature
• One (1) serial port available on the RTM face plate through one (1) RJ-45 connector
• RS-232 signals level at RTM face plate connector.
• Serial port speed capability is: 9.6kbits/s to 115.2kbits/s.
1.6.1.3 FRU Data EEPROM
• FRU Data EEPROM size is 32Kbit and it includes board identification and serial number.
1.6.1.4 Hot Swap
As a Hot Swappable Intelligent Managed FRU, the RTM8050 (FRU2) includes a Management Controller, the
AdvancedTCA Hot Swap indicator (Blue LED), and the standard AdvancedTCA handle switch.
The RTM8050 includes a PCI-Express SAS controller; proper PCI-Express Hot-Plug support is required in O/S
to complete hot-extract and hot-insert cycles.
As a Hot Swappable Non-Intelligent Managed FRU, the RTMHDD (FRU3) mezzanine adds support for SAS hot
swapping; it includes its own ejector latch and Blue LED, under control of the front board's IPMC.
WARNING
All the managements infrastructures are present for hot-swap, but the user must
take the proper action to protect its data under the OS installed on the Front Board
