New Hardware Features in Cisco IOS XE Release 3.10S

Dust Filter (A903-FAN-F)

The dust filter on the fan tray is a quadrafoam 45PPI filter which is 85 percent dust resistant. For
information on installing the dust filter, see
Router.

Dummy Cover (A903-FAN-F-B)

A dummy cover (A903-FAN-F-B) secures the dust filter in the chassis. For installing the fan filter, see
For information on installing the dummy cover on the fan tray, see
Aggregation Services Router.

Cable Bracket (A903-CAB-BRACKET)

The cable management bracket helps in routing the cables from the interface modules; therefore enabling
a proper cable bending radius. For installing the bracket, see
Aggregation Services Router.

Air Plenum

Air Plenum or air baffle assembly is used change the air flow pattern of the unit. When the router is
installed with the plenum, the air flow pattern is changed from side-side to front-back. For information

New Hardware Features in Cisco IOS XE Release 3.10S
The IOS XE 3.10S Release for the Cisco ASR 903 Router introduces the following hardware features:

Serial Interface Module

IOS XE Release 3.10(0)S introduces support for the serial interface module, which is designed to
provide a low-latency communication platform for legacy interfaces. Designed for utilities, the module
is hardened to accommodate the wide operating temperature swings, EMI and surge spikes, and dust
found in substation environments.
The combination of the Cisco ASR 903 Router and the serial interface module enables migration from
TDM and serial networks to an IP-based network that can control latency and jitter across the network
and enable multiple Smart Grid applications.
The Cisco ASR 903 Serial Interface Module supports the following standards:
