Hello dear Jay
For sure, when not talking about hiX56xx the private extension SHE-PHYSICAL-MIB won’t help here.
But there might be some last chance to try. 
IMHO the standard entityMIB could be the right thing here. See part below.
Thus you might try a SNMP walk over 1.3.6.1.2.1.47.1.1.1.1.14 - good luck
Cheers, Frank

entPhysicalAlias OBJECT-TYPE
SYNTAX SnmpAdminString (SIZE (0..32))
ACCESS read-write
STATUS current
DESCRIPTION
"This object is an 'alias' name for the physical entity as
specified by a network manager, and provides a non-volatile
'handle' for the physical entity.
On the first instantiation of an physical entity, the value
of entPhysicalAlias associated with that entity is set to
the zero-length string. However, agent may set the value to
a locally unique default value, instead of a zero-length
string.
If write access is implemented for an instance of
entPhysicalAlias, and a value is written into the instance,
the agent must retain the supplied value in the
entPhysicalAlias instance associated with the same physical
entity for as long as that entity remains instantiated.
This includes instantiations across all re-
initializations/reboots of the network management system,
including those which result in a change of the physical
entity's entPhysicalIndex value."

entPhysicalEntry OBJECT-TYPE
SYNTAX EntPhysicalEntry
ACCESS not-accessible
STATUS current
DESCRIPTION
"Information about a particular physical entity.
Each entry provides objects (entPhysicalDescr,
entPhysicalVendorType, and entPhysicalClass) to help an NMS
identify and characterize the entry, and objects
(entPhysicalContainedIn and entPhysicalParentRelPos) to help
an NMS relate the particular entry to other entries in this
table."
