Service manual

CAUTION: Special care must be taken when handling processor modules.
See Section 5.11 before replacing this module. Also review the configuration
rules in Section 5.3.
While removing or inserting a module in the XMI card cage, you must hold
the XMI card cage lever. Failure to do so may result in damage to the
module.
1. Turn the upper key switch straight up to the Off position (0).
2. Open the cabinet door and remove the plastic door in front of the XMI
card cage.
CAUTION: You must wear an antistatic wrist strap attached to the
cabinet when you handle any modules.
3. Disconnect the VIB cable (17-02240-03) from the vector module.
4. Remove the defective vector processor module.
5. Take the new vector processor module from the ESD box and insert it
in the XMI card cage. Place the defective module in the ESD box.
6. Attach the connecting VIB (vector interface bus) cable. The keyed end
of the cable attaches to the vector module.
7. Press the lever down to close the connector.
8. Replace the plastic door and shut the cabinet door.
9. Turn the lower key switch to Halt and the upper key switch to Enable.
10. Check the self-test display for the new vector processor, indicated by a
V on the TYP line.
11. If the processor shows a plus sign (+) on both lines STF and ETF, it
passed self-test.
NOTE: Installation of an <REFERENCE>(xrv) vector processor requires
that the attached <REFERENCE>(XRP) module (T2015) be at a
minimum revision of K. In addition, the ROMs on any additional
<REFERENCE>(XRP) modules must be at a minimum revision of V2.0
(ROM 0 and ROM 1).
