Blank Deflector (A900-IMA-BLNK-DEF)
The A900-IMA-BLNK-DEF is a special type of blank filler plate that can be used in empty interface module
slots. In addition to just acting as a filler for the empty slots in the router, this blank deflects additional air
towards the interface modules in the slot below it, thereby enhancing the cooling for the interface module.
The A900-IMA-BLNK-DEF module should not be used in slot 0 in the Cisco ASR 902 Router.
Caution
For slot 0, always use the filler blank (A900-IMA-BLANK) when a blank filler needs to be used.

Maximum Operating Ambient Temperature Support for RSP3 Modules
The router supports multiple fan trays with different cooling capacities. The maximum operating temperature
of the router using the RSP3 modules, depends on the fan tray and the interface modules used in the router.
