RPM Online Insertion and Removal
Dell Force10 systems are functional with only one RPM. If a second RPM is inserted, it comes online as
the standby RPM, as shown in Figure 18-4.
On the C-Series, when a secondary RPM with a logical SFM is inserted or removed, the system must add
or remove the backplane links to the switch fabric trunk. Any time such links are changed, traffic is
disrupted. Use the command
redundancy sfm standby to avoid any traffic disruption when the secondary
RPM is inserted. When this command is executed, the logical SFM on the standby RPM is immediately
taken offline, and the SFM state set as standby. Use the command
show sfm all to see SFM status
information.

Line Card Online Insertion and Removal
FTOS detects the line card type when you insert a line card into a online chassis. FTOS writes the line card
type to the running-config and maintains this information as a logical configuration if you remove the card
(or the card fails), as shown in Figure 18-5.
