A KVM session to the target device opens, and the administrator can

If Stealth is not listed as an option, one of the following conditions exist:
• the switch to which the target device is connected is not configured to
allow Stealth Connections
• you do not have the necessary access rights (Stealth permissions follow
Preemption permissions)
• the switch the target device is connected to is not a Remote Console

Preemption Mode
Preemption provides a means for users with sufficient privilege to take control of
a server from another user with lesser or equal privilege.
NOTE: All users sharing the connection that is being preempted will be warned, but
only the primary user will be able to reject the preemption (if allowed).
Table 4-3 outlines the preemption scenarios and detailed scenarios in which
preemption requests can be rejected. For information about preemption and
reserved or locked virtual media sessions, see "Session Sharing Options" on page
85.
