2-Port 10 Gigabit Ethernet SFP+ Interface Module
The 2-port 10 Gigabit Ethernet interface module provides a dual port supporting a 10 Gigabit Ethernet SFP+
and XFP module.

For information on supported SFP modules, see Cisco ASR 900 Series Aggregation Services Routers Data
Sheet.
For more information about installing the 2-port 10 GE SFP Gigabit Ethernet module, see Interface Module
Installation.
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 is module should not be used in slot 0 in the Cisco ASR 903 Router.Caution
For slot 0, always use the filler blank (A900-IMA-BLANK) when a blank filler needs to be used.
For more information on operating temperature, see Example: Configuration with A900-RSP3-200-S with
Blank Deflector (A900-IMA-BLNK-DEF).
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.
The tables below provide and overview of the operating ambient temperature limits for different fan tray and
interface module combinations. These values are specified for side-to-side airflow configuration.
