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.
The following table lists the contents of this chapter.

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
Figure 1.1 shows the appearance of the support.

There are four types of support: three types of height-adjustable support and one
type of fixed-height support. Figure 1.1 lists the range of the adjustable height for
each type.

IV Customised to the

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.

Drill
Drill bit (Ф16)
Expansion bolts M12
Dust cleaner
Rubber hammer
Prerequisites

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 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.

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 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.

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.

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.

insulation of the cabinet and the support should be fully satisfied. Insulation
measures are taken if the user-supplied mount base is used.

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. 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.

The cabinet label is properly pasted on the cabinet.
