3.2 RTM8030
The RTM8030 is a single slot (6HP) ATCA Rear Transition Module. This RTM provides additional connectivity to
the Kontron AT8030 CPU board and the AT8404 10G AMC Carrier board. This chapter describes the RTM fea-
tures which are usable for the AT8404. For a general and AT8030 specific description, please refer to the
RTM8030 User's Guide.
The RTM8030 has a connector (P30) with 40 differential pairs which contact the corresponding counterpart
on the AT8404 (J30). The connector pinning can be found in section 3.1.8.
Following features are offered by the RTM8030 for operation with the AT8404:
• Hot swap mechanism
• Unit Computer RS232 management interface
• Unit Computer FE management interface
• One GbE SFP port (connected to the front board GbE switch)
• Two external SAS connections
• Optional SAS Hard Drive
Typical power dissipation of the RTM8030 is 10W. Operation of the optional hard drive increases power con-
sumption to 20W.
Note...
Not all of the front plate elements are used in combination with the AT8404. E.g., the
USB port and rotary switch are only used for operation with the AT8030.
WARNING
There is a risk of damaging the AT8404 or the AMC when enabling the
serial connection for an AMC that does not support this feature.
Note...
When using AT8030 RTM with AT8404 carrier, by default the serial connection
between RTM and AMC on carrier will not be granted.
Default E-Keying prevents such connection.
Default E-Keying behaviour could be change by the user in order to permit serial con-
nection between RTM and AMC on AT8404 ATCA carrier but the following limitation
will apply.
AT8030 RTM are equipped with rotary switch that permits to redirect RTM serial con-
nection to different AMC on carrier. There is a risk to damage AMC by changing the
selection with the RTM rotary switch. This risk is only present once serial connection
has been established between RTM and an AMC on ATCA carrier.
