What's the best/safest way to "cat" the following job into crontab?

*/3 * * * *  /usr/lib64/nagios/plugins/check_megaraid_passive.sh > 
/dev/null 2>&1

I am used to doing this manually via crontab -e, but now I simply have 
too many centos servers to build in a given week (get to toss another 
120K at some more 2U chenbro/tyan/amd64's -w000ooo).
