12 RTM-ATCA-SXXX
Installation
This chapter contains the procedures for installing and removing the RTM-ATCA-SXXX.
12.1 Installation and Removal of the Rear Transition Module
The RTM-ATCA-SXXX can be installed into an ATCA shelf (chassis) with a midplane
made for front and rear board installations. The module must be installed in the slot
directly behind the host ATCA node board. These back-to-back slots have common
pins to enable passing of signals via the Zone-3 connector complex.
12.2 Important Information about Your Chassis
Before installing the rear transition module, verify the module’s part number to
ensure that the correct rear transition module is being installed into the system. For
information on identifying the rear transition module, see Section11.6.
12.2.1 Safety Statement
The RTM-ATCA-SXXX is designed to comply with UL60950-1, and is intended to be
used with similarly tested ATCA products that have a user’s guide detailing user
installation of module accessories.
12.2.2 Observe Maximum Module Current Requirements
There are several manufacturing options for the RTM. The diskless version of the
RTM requires no power from the front ATCA node board, but may draw up to
200mA from the 3.3 V management power source. Be sure to validate that the host
chassis can supply the RTM slot with these maximum current requirements.
