Msm Physical Features - Extreme Networks BlackDiamond 8806 Hardware Installation Manual

BlackDiamond 8000 Series Modules
Selection of the primary MSM occurs automatically. The following examples describe the selection
process:
When a switch boots with two MSMs installed, the MSM in the lower-numbered slot becomes the
●
primary MSM. In the BlackDiamond 8810 switch this is slot 5; in the BlackDiamond 8806 switch, this
is slot 3.
When a switch boots with a single MSM (regardless of the slot position), it is selected as the primary
●
MSM.
If a second MSM is added to the switch after it has been powered up, the added MSM becomes the
backup MSM. MSMs that operate as backup MSMs can be inserted and removed without disrupting
network services.
If you remove the primary MSM while the switch is operating, the backup MSM performs a soft
●
reset and then becomes the primary MSM.
For example, in a BlackDiamond 8810 switch with a primary MSM in slot 5 and a backup MSM in
slot 6, if you remove the primary MSM from slot 5, the backup MSM in slot 6 becomes the primary
MSM.
