3.2. OpenScape 4000 SoftGate Upgrade 
The functionalities of both the virtual HG 3575 and the virtual HG3500
(HFA/SIP) are contained in the OpenScape 4000 SoftGate image. All functionalities
are therefore always upgraded at the same time in a OpenScape 4000 SoftGate
upgrade.
The upgrade is performed either via LW Update Manager (see
Section 2.1,
“Upgrade via Loadware Update Manager”) or via the
board’s local WBM application (see Section 2.2,
“Upgrade via the Local WBM in OpenScape 4000 SoftGate”).
