• RS-232 signal levels at RTM face plate connector.
• Serial port speed capability is: 9.6kbits/s to 115.2kbits/s.
1.6.1.3 Debug Video Feature
A header is present on the RTM to connect a debug video cable. This interface is suitable for low rate video,
not for HD or intensive use. Video signals are VGA standard signals. Custom video cable available on demand,
please contact Technical Support.
1.6.1.4 Hot Swap
The RTM 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 RTM806X is
removed. This procedure meets the AdvancedTCA AMC behavior.
1.6.1.4.1 Inserting the RTM 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
knowing the type of RTM inserted, the IPMC negotiates with the shelf manager in order to activate the +12V
payload power.
After RTM local voltages ramp up, the front board IPMC informs the shelf manager there is a functional RTM
blade present.
1.6.1.4.2 Removing the RTM from the slot
The RTM_EJECT signal goes HIGH by opening the RTM lower ejector handle. This indicates to the front blade
IPMC that a hot swap action is going to take place. The IPMC then negotiates the removal with the System
manager and if it is granted, it proceeds with the removal process.
The IPMC proceeds to the deactivation by disabling ekey governed links, the IPMC then turns OFF the payload
+12V power. When it is safe to remove the RTM blade from the slot, the IPMC turns the Blue / Hot Swap LED
ON. Front Blade IPMC turns OFF the management power only when there is no RTM detected. (RTM806X
removed from the slot)
1.6.2 Advanced Mezzanine Card
The AT8060 has one AMC bay. Using a mezzanine allows to add storage or I/O not provided on board.
1.6.2.1 AMC Expansion
The AMC slot provides an AMC.1 type 4, AMC.3 SATA. This means that the following signaling are supported:
• PCI-Express Gen2 X8 on AMC ports 4-11
