You need to make sure that people outside your group know you, and have a generally favorable impression of you.
Of course you have to do a good job within your department, on the work and task that you have been assigned by your manager. But this is a mere condition of continued employment. It is necessary, but not sufficient, for you to advance your career. To advance and succeed, you will need to get out and about.
