(a) [Possession; rendering equipment unusable; disposition on debtor's premises.]
After default, a secured party:
(1) may take possession of the collateral; and
(2) without removal, may render equipment unusable and dispose of collateral on a debtor's premises under Section 9-610.
(b) [Judicial and nonjudicial process.]
A secured party may proceed under subsection (a):
(1) pursuant to judicial process; or
(2) without judicial process, if it proceeds without breach of the peace.
If so agreed, and in any event after default, a secured party may require the debtor to assemble the collateral and make it available to the secured party at a place to be designated by the secured party which is reasonably convenient to both parties.
