Chapter 17. Power-On Procedure; Introduction; Visual Inspection - C-DOT DSS MAX-XL Installation Manual

17.1. INTRODUCTION

This chapter describes the power on procedure of the C-DOT MAX-XL system. This
procedure is to be followed after installation has been done as per Chapters 1 to 16
of this manual. It should be ensured that no cards are to be inserted in any of the
cabinets at this stage. MCBs or fuses at DCDPs, PDP and IOP-PDP should be in
"OFF" position and power cables should be disconnected from switching cubicle.
This activity can be sub divided into following groups in sequence.

Visual Inspection

Electrical Tests

17.2. VISUAL INSPECTION
96 pin Euro connectors on the mother-board of terminal units of modules should be
straight and rigidly mounted such that an easy jacking in of cards are possible. The
movement of cards into the slots should be free.
There should not be any shorting of any pin in the Euro-connector (96 pins) at
•
the back-plane as well as at the front side where we insert the cards.
Bus bars extended over switching cubicle should be coated with proper colour
•
(Red & Blue).
All the power and ground cable lugs should be terminated tightly. There should
•
not be any loose termination.
Check whether all -48V filter boxes are properly mounted or not. In addition to
•
this all filter box fuses should be checked for their rating in BMs, LMs & CM.
MCB/Fuse rating of suite PDPs and IOP-PDP are to be checked also. Also verify
the polarity of filter boxes.
Ensure that all filter boxes are rigidly fixed to the -48V bus bars.
•
Remove the protections provided for disk and cartridge drive of both the IOPs.
•
They should be visually inspected whether they have any, scratches, damages
etc. All the cables terminated on IOPs should be properly connected.
