Set the Expander Cabinet ID Number
Set the cabinet ID number on the front door OCP push
wheel according to these rules for setting cabinet IDs:
Each cabinet has a unique ID defined by the setting two
push-wheel switches on the back of the door OCP. There
are two exceptions to this rule that occur when either a
32P is formed by two 16P systems side-by-side or a 64P
system is formed by two 32P systems side-by-side.
Otherwise the following rules apply to cabinet IDs:
• The leftmost system cabinet has an ID of 00.
• All subsequent cabinet IDs are incremented as
cabinets are added to the platform first to the right
and then to the left of the first system cabinet.
(Orientation is the front of the system.)
The result of these rules is that all cabinets to the right of
cabinet 0 have odd ID numbers and all cabinets to the left
of cabinet 0 have even ID numbers.
Legal cabinet ID numbers are in the range 00:0F; the left
most number must be 0. Note that the switches on the
back of the OCP are oriented right to left and the display
on the front is oriented left to right. This means that the
switches will look like a range 00:F0.
Set the Expander Drawer ID Number(s)
If the cabinet has I/O drawers, set the push wheel ID
number on the drawer OCP according to the rules for
setting drawer IDs contained in the AlphaServer
ES47/ES80/GS1280 Installation Information, Revision
3.0.
Attach Cables to Expander Cabinet Devices
Cabling depends upon the contents of the expander
cabinet and the contents of the base cabinet. I/O drawers
must be connected using an IP cable to an I/O CPU
connector. Storage shelves must be connected to storage
shelf controllers in I/O drawers.
