Logging in to PSN

[Dotini]

I'm trying to log in, but get a message that says I need a systems software update, and go to (Settings) >(System Update) and perform the update. But I do not see any System Update option when I go to My Home Settings > Options. What am I missing? What is Clear System Cache?

Grateful for help,
Dotini
