3 Installing a Cabinet on

the Antistatic 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

 Installation on the cement floor (see Chapter 4 "Installing a cabinet 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 antistatic 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

There is no antistatic floor between the cabinet and the support

 Note

To install multiple cabinets of the same type side by side, you only need to install the side doors at two ends of the row of cabinets

3.2 Positioning the Cabinet

This section guides you to mark the installation position for the cabinet on the antistatic floor The position varies with the number of cabinets and their layout

3.2.1 Positioning a Cabinet Independently

Purpose This procedure guides you to position a cabinet which is

installed independently.

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

drawing

of the installed cabinet

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

step 1

Step 3 Draw the front outline of the cabinet to be installed according to the front outline

of the cabinet already installed

Step 4 Mark the installation reference point

Step 5 Draw a 600 mm x 300 mm rectangle as shown in Figure 1.1 according to the

3.2.5 Checking the Positioning

Check the positioning as the following items

 The minimum distance between two rows of cabinets is 1 m

 The minimum distance between the cabinet side and the wall is 0.8 m

 The minimum distance between the front/back of the cabinet and the wall is 1 m

 An aisle at least 1 metre wide is reserved in the equipment room

 The cable outlet on the top of the cabinet is aligned with the lower part of the cabling trough of the equipment room

 The position for installing the cabinet is correct and meets the requirements in the construction drawing

3.3 Positioning the Support

This section describes how to position the support in the equipment room An S300A support assembly is used to support the cabinet It also facilitates floor installation and cabling Each cabinet needs one S300A support assembly ("support" hereinafter)

3.3.1 Types of the Support

within their ranges, by moving the upper and lower supports.

floor height (minimum 100 mm)

Support IV is of fixed-height It is applied to the extra-high or extra-low antistatic floor The floor for this type of support must be at least 100 mm high.

3.3.2 Positioning the Support on the Floor

Purpose This procedure guides you to position the support on the

floor after positioning the cabinet.

Tools /Materials Pencil

Ruler

Prerequisites The cabinet has been positioned.

Required/As needed Required if the cabinet is installed on the antistatic floor.

Step 1 Draw a 460 mm x 264 mm rectangle according to the central lines (see the dotted

rectangle in Figure 1.1) One side of this rectangle is 41.5 mm away from the back

of the cabinet

Figure 1.1 Mounting holes for the support (a single cabinet)

Step 2 The four vertexes of the dotted rectangle are the mounting holes for the support

Mark them with a marking pen

Caution

Check whether the mounting holes are fit for the support to eliminate any possible mistakes

End 3.4 Installing the Support

Purpose This procedure guides you to install the support on the floor.

Tools /Materials Drill

Drill bit (Ф16) Expansion bolts M12 Dust cleaner

Rubber hammer

Prerequisites The support has been positioned.

Required/As needed Required if the cabinet is installed on the antistatic floor.

Caution

A dust cleaner 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, as shown in Figure 1.1

Bolt Expansion tube Guide slot on expansion tube Expansion nut Guide rib on expansion nut

Figure 1.1 Installing the expansion tube and expansion nut

Step 5 Drive the expansion tube completely into the floor with a rubber hammer.

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

Step 7 Use height adjusting screws to level the height indicator on the support with the

height of the antistatic floor See 3.3.1 I I Step 1Figure 1.1

Step 8 Tighten the height-locking bolt on the support

Caution

Follow the principle of "middle first, sides later", that is, tighten the middle height locking bolt first and then that of both sides

Step 9 Align the support installation holes with the expansion bolt holes on the floor

Step 10 Mount the spring washer and flat washer on the bolt M12 x 60

Step 11 Insert the bolt vertically into the expansion hole through the support installation

hole

Step 12 Check the support position and fix the bolt M12 x 60 See Figure 1.1

3.5 Installing the Cabinet on the Support

Purpose This procedure guides you to install the cabinet on the

support.

Tools /Materials Horizontal ruler

M12 x 40 bolt Insulation plate Washer

Prerequisites The support has been installed.

Required/As needed Required if the cabinet is installed on the antistatic floor.

Caution

At least three persons are required to install the cabinet on the support

Step 1 Place the two insulation plates on the support with the holes aligned from the top

down See Step 2Figure 1.1

Step 2 Place the cabinet on the plates with the holes aligned from the top down See

Figure 1.1

Insulation plate

Figure 1.1 Placing the cabinet and the insulation plates

Step 3 Adjust the levelness of the cabinet by adding washers between the insulation

plates and the support See Figure 1.1

Caution

If the washers are not inserted between the insulation plates and the support, insulation between the cabinet and the floor cannot be guaranteed

Washer

Figure 1.1 Leveling the cabinet

Step 4 On the top of the cabinet, place the level instrument in two perpendicular

directions to check the levelness of the cabinet

Step 5 Vertically insert the M12 x 40 bolt assembly through the lower enclosure frame of

the cabinet, and into the connecting hole of the support See Figure 1.1

M12X40 bolt

Insulation washer

Figure 1.1 Securing the cabinet on the support Step 6 Tighten the bolts alternately to reduce the stress between the bolts and the cabinet

Step 7 Measure the resistance between the support and the cabinet The normal resistance

should be larger than 5 megaohm

 If the measured resistance is less than 5 megaohm, demount the cabinet and check the insulation components Then repeat the operations from step 1

 If the measured resistance is larger than 5 megaohm, continue to the next step

Step 8 Fix the horizontal pallet and side pallet to the support See Figure 1.1

 If a cabinet is separately installed (no other equipment around), it needs to fix both the horizontal and side pallets on the support with M12 x 30 bolts

 If several cabinets are installed side by side, only the leftmost and rightmost support need side pallets
