I am trying to determine the height of an ASR9010. One Cisco site says 17.50inch: http://www-tss.cisco.com/eservice/est-unified/router/asr9000/vho/spec_9010.html#anchor1 and another site says 36.75inch: http://www.cisco.com/c/en/us/td/docs/routers/asr9000/hardware/installation/guide/asr9kHIGbk/asr9kIGapaspecs.pdf Which site should I trust? Thanks, Hank
