4 Installing a Cabinet on the Cement

Floor

About This Chapter

When the installation is well prepared, install the cabinet There are three modes for installing the cabinet according to the floor of the equipment room

 Installation on the antistatic floor (refer to Chapter 3 "Installing a cabinet on the antistatic floor")

 Installation on the cement floor

 Installation on the wooden floor (the same as the installation on the cement floor)

This chapter guides you to install the cabinet on the cement floor We recommend

reading OptiX OSN 3500 Intelligent Optical Transmission System Compliance

and Safety Manual This helps you to ensure a safe and smooth installation.

The following table lists the contents of this chapter

4.1Installation Flow and Expected Result

Describes the installation flow and expected result.

4.2Positioning the Cabinet Marks the cabinet position for the cabinet.

4.3Installing the Cabinet Describes the operations and procedures for

installing the cabinet.

4.4Checking the Cabinet Installation

Describes the check points of the installation.

4.1 Installation Flow and Expected Result

4.2 Positioning the Cabinet

This section describes how to position the cabinet on the cement floor The position varies with the number of cabinets and their layout

4.2.1 Positioning a Cabinet Independently

Purpose This procedure guides you to position a cabinet which is

installed independently.

Tools /Materials Pencil

Ruler

Prerequisites The cabinet and the accessories (including the support and

fixing pieces) have been transported to the site.

Required/As needed Required if the cabinet is installed independently.

Caution

Read technical documents on construction before you mark the installation position for the cabinet

Step 1 Mark the reference point for installing the cabinet according to the construction

documents

Step 2 Draw a 600 mm x 300 mm rectangle according to the reference point, and then

mark the central lines for the cabinet See Figure 1.1

4.2.2 Positioning a Cabinet Close to an Installed Cabinet

Purpose This procedure guides you to position a cabinet close to an

installed cabinet.

Tools /Materials Pencil

Ruler Plummet

Prerequisites The cabinet and the accessories (including the support and

fixing pieces) have been transported to the site.

Required/As needed Required if the cabinet is installed close to an installed

cabinet.

Step 1 Use a plummet to determine and mark the side projective position of the cabinet

already installed

Step 2 Draw the side outline for the cabinet to be installed according to the marks made

in step 1

Step 3 Draw the front outline for the cabinet to be installed, according to the front outline

of the cabinet already installed Then determine the installation reference point

Step 4 Draw a 600 mm x 300 mm rectangle according to the installation reference point

Then draw the central lines for the cabinet See Figure 1.1

4.3 Installing the Cabinet

Purpose This procedure guides you to install the cabinet on the

cement floor.

Tools /Materials Drill

Drill bit (Ф16) Dust cleaner Rubber hammer M12 x 60 expansion bolts

Prerequisites The bolt holes of cabinets are positioned.

Required/As needed Required.

Caution

A dust catcher is recommended to remove the dust in the course of drilling Clean out the dust inside before measuring the depth of the holes

Step 1 Drill holes on the marked positions The depth of the four holes ranges from 52

mm to 60 mm

Step 2 Remove the expansion tube and nut from the expansion bolt

Step 3 Insert the guide rib on the expansion nut into the guide slot on the expansion tube

Step 4 Put the expansion tube and nut vertically into the hole See Figure 1.1

Bolt Expansion tube Guide slot on expansion tube Expansion nut

Step 6 Repeat steps 2–5 to install the other three expansion tubes and expansion nuts.

Step 7 Prior to the cabinet installation, lay the insulation plates on the floor Each cabinet

needs two plates See Step 9Figure 1.1

Step 8 Align the holes on the insulation plate with the fixing holes on the floor See

Step 9Figure 1.1 Insulation plates can not extrude from the cabinet

Step 9 Put the cabinets upon the floor See Figure 1.1

Insulation plate

Figure 1.1 Placing the insulation plate and the cabinet

Step 10 Place a horizontal ruler at the cabinet top plane in two perpendicular directions to

check its horizontal level If it is not leveled, level it by inserting washers at the lower end See Figure 1.1

Caution

The washers for leveling purpose should be inserted between the insulation plate and the floor Insulation will not be effective if these washers are inserted between the insulation plate and the cabinet

Figure 1.1 Leveling the cabinet

Step 11 Put the spring washer and flat washer along with insulation covering onto the

M12 x 60 bolt

Step 12 Insert the bolts vertically, through the lower frame of the cabinet and the hole on

the insulation plate, into the fixing hole on the floor See Figure 1.1

not sufficient Remove all installation parts, and check whether there is no insulation plate installed or whether it is damaged Fix the cabinet and test insulation again

-End 4.4 Checking the Cabinet Installation

The following requirements should be met when the cabinet is installed properly

 The installation position of the cabinet meets the requirements in the engineering design drawing

 All bolts are installed correctly and firmly The sequence for installing the spring washer and flat washer is correct

 The cabinet should be kept upright, and the horizontal deviation shall not be more than 3 mm

 The main walkway in the equipment room should be lined up with a deviation less than 5 mm The adjacent cabinets should be in line

 All bolts on the cabinet are equipped with flat washer and spring washer, and all are screwed tight

 No part of the cabinet is distorted

 The exterior varnish and the marks on the cabinet should be kept intact, and the marks and signs should be correct, clear, and complete
