Recovering SuperNode SE application specific units
Application
Use this procedure to manually recover application-specific units (ASU)
residing on a SuperNode SE link interface shelf (LIS) or enhanced network
interface (ENI) shelf. Application-specific units include:
• network interface units (NIU)
• Common Channel Signaling 7 (CCS7) link interface units (LIU7)
• CCS7 server (SVR7)
• Ethernet interface units (EIU)
• high-speed link interface unit (HLIU)
• high-speed link router (HSLR)
• voice processor units (VPU)
• application processor units (APU)
• X.25/X.75 link interface units (XLIU)
• frame relay interface units (FRIU)
To recover ASUs which reside in a link peripheral processor (LPP) cabinet,
refer to the procedure Recovering link peripheral processors in this document.
To recover ASUs which reside in an enhanced LPP (ELPP) cabinet, refer to the
procedure Recovering enhanced link peripheral processors in this document.
If the entire switch has lost power, do not use this procedure until you have first
restored primary switching functions using the procedure Recovering from a
dead system in this document. Recover the ASUs when directed to do so by
that procedure.
Action
The following flowchart provides an overview of the procedure. Use the
instructions in the step-action procedure that follows the flowchart to perform
the recovery task.
