line adapter from the NCP as follows:
a. From menu 3, select TSS Services

Refer to Figure 1-5 on page 1-64. If nec-
essary, refer to “How to Run Internal Func-
tion Tests” on page 3-9. Then go to

The entire machine is required. Ask the customer
to deactivate all the lines attached to the 3745
and to deactivate NCP. Then refer to “How to
Run Internal Function Tests” on page 3-9.
Note: You must never run the HPTSS/ESS diag-
nostics under concurrent maintenance
before exchanging a probably defective
CSP card. This would cause other line
adapters to go down.
