Environmental specifications
IXB2850 boards have been tested to Network Equipment Building System (NEBS)
Level 3. A report documenting the tests and results is available on request. Contact
your Intel representative for more information.
Reliability Specification
MTBF
The predicted MTBF values are calculated according to Reliability Prediction for
Electronic Equipment, SR-332 Issue 1, Telcordia Technologies, May 2001, but scaled
with suitable modifiers based on Intel field failure data for a similar product, to reflect
performance in the field.
The MTBF for IXB2850 boards are as follows:
MTTR
The target Mean Time to Repair (MTTR) for IXB2850 boards is 1 hour for a staffed CO,
with replacement boards on-site. For an unstaffed Central Office (CO), the MTTR shall
include an additional 3 hours for dispatch and travel time, and 1 hour for locating and
replacing the board. This is a total of 4 hours.
