Checking the Installation

Procedure

1. Check the device installation.

   Table 4-22 lists the device installation check items.

   Table 4-22 Device installation checklist

   Item	Normal	Abnormal
   Controller enclosure	Stably installed on the guide rails without displacement Tightly screwed Disk modules for controller or disk enclosures are Huawei-certified and match the product model. If disk modules of disk enclosures are not fully configured, ensure that the vacant slots have been equipped with filler panels. If interface modules of disk enclosures and controller enclosures are not fully configured, ensure that the vacant slots have been equipped with filler panels.	Devices are slanted. The screws are loose or missing. Disk modules for controller enclosures or disk enclosures do not pass Huawei certification and do not match the product model. The vacant disk module slots of disk enclosures have not been equipped with filler panels. The vacant interface module slots of disk enclosures and controller enclosures have not been equipped with filler panels.
   Disk enclosure
   Filler panel	The vacant slots in the cabinet are covered by filler panels.	The vacant slots in the cabinet are not covered by filler panels.
   Overall	Stably installed without displacement Tightly screwed	One or more devices displaced One or more devices titled Loose or detached screws

2. Check whether the cables have been laid out properly.

   Table 4-23 lists cabling items to check.

   Table 4-23 Cable layout checklist

   No.	Item
   1	Labels are correctly attached to cables.
   2	Cables are laid out in an untangled and orderly fashion.
   3	Cables that pass the cable ladder are secured on the beam of the cable ladder.
   4	Cable troughs are used for cables laid outside a bay, and these cables are in the cable troughs.
   5	The bending radius of optical fibers is equal to or larger than 50 mm.
   6	Power cables and ground cables are bent smoothly.
   7	Power cables and ground cables are connected correctly and securely.
   8	Ground cables of a bay are connected correctly and reliably.
   9	The diameter of the power cables and ground cables meets the power distribution requirements.
   10	Do not tightly bind the external power cables and ground cables. Separately deploy them with at least 150-mm space in between. Also, separately deploy these two types of cables from the signal cables with at least 30-mm in between.
   11	If there are many cables, they should be bound neatly in a rectangular shape (circular when the cables are single-cored).
   12	At the turning point, cables are bent with a bend radius of more than 60 mm and cannot be bound on the bend point.
   13	Optical fibers are laid out without using force or having unnatural bends.
   14	Weld or crimp OT terminals of the power cables and ground cables firmly.
   15	Use protection tubes or insulating adhesive plasters to wrap power cables, ground cables, and OT terminal handles. There should be no bare copper wires on OT terminals. Spacers are correctly installed.
   16	Spring washers and flat washers should be installed properly. Properly ground all cabinets and enclosures with metal or partially metal shells.
   17	All fibers are properly bound. The space between the cable ties is even, and the remaining parts of the cable ties are cut off neatly. All the cable ties face the same direction for a neat appearance.
   18	Ground cables are olive or yellow.
   19	Power cables and ground cables use the entire copper core and no joint.
   20	Fill in and attach the labels on the power cables and ground cables. These labels are tidily located and face the same direction for users' convenient check.
