1.4 Compliance
This product conforms to the following specifications:
• PICMG3.0 R3.0 (Advanced TCA Base Specification)
• PICMG3.1 R1.0 (Ethernet/Fiber Channel over AdvancedTCA)
• PICMG3.1 R2.0 (AdvancedTCA Ethernet specification(Draft))
• HPM.1
• IPMI 2.0
1.5 Hot-Plug Capability
The AT8242 supports Full Hot Swap capability as per PICMG3.0 R3.0 for the board itself. It can be removed
from or installed in the system while it is on (without powering-down the system). Please refer to the
PICMG3.0R3.0 specification for additional details about Hot Swap.
1.6 Interfacing with the Environment
1.6.1 RTM (rear transition module)
The RTM8242 is a single slot (6HP) AdvancedTCA Rear Transition Module. This module provides additional
connectivity for AT8242 CPU front blade.
1.6.1.1 Standard Compliance
• PICMG3.0 R3.0 - Advanced Telecommunication Computing Architecture
1.6.1.2 Hot Swap
The RTM8242 supports hot swapping by using the switch connected to the face plate lower ejector. This
switch indicates the coming hot swap action. The insertion of the RTM to a slot is always done over a non
powered connector. During the extraction procedure, the management power is disabled only when the
RTM8242 is removed. This procedure meets the AdvancedTCA AMC behavior.
1.6.1.2.1 Inserting the RTM8242 into the slot
The presence of the RTM is indicated by one signal. The front blade IPMC recognizes the RTM insertion when
the signal is low. After recognizing the RTM, the IPMC turns the blue LED ON and enables the management
power to the RTM. Once the IPMB-L link is working, the IPMC accesses the MMC to retrieve FRU data. After
