View ArticleLine rate capacity dependency on SCB
If I have 3 CB slots available on my MX device and I install all 3 of them how will that affect the rate capacity on line card installed. Do I really need 3 SCBs in place?
View ArticleRe: Line rate capacity dependency on SCB
Two SCB are capable to handle the full capacity of lin cards, third SCB is for redundancy purpose, if any of the first two SCBs goes down, then the third standby will take over.

Hi Reload, There is a solved query regarding this on our forum : "Redundancy in Fabric depends on mode at which SCBE3-MX cards are operating at, there are 2 modes [increased-bandwidth | redundant] and...
View ArticleRe: Line rate capacity dependency on SCB
This means my third SCB is for worst situation case. One a 2 RE device. I think if 2 SCBs are fine, third one won't even be needed until one of the SCBs cause issue.
View ArticleRe: Line rate capacity dependency on SCB
Yes, the third SCB is to maintain 2+1 redundancy. Which comes into play when there is an issue with one of the active ( primary and backup ) SCBs.
