BTS3900 LTEInstallation Guide About This Document


iii

The BTS3900 cabinets are delivered with boards are installed. The installation procedureinvolves installing the base, cabinets, and cables on site. In addition, some optional componentscan be installed on site as required.

5 Unpacking the Equipment

You need to unpack and check the delivered equipment and ensure that all the materials areincluded and intact.

6 Checking the Installed Modules and Cables

The internal modules and cables are installed in the cabinet before delivery. You need to checkthat the modules and cables are securely connected.

7 Installing the Base

The BTS3900 cabinet must be installed on the base. The base can be installed on the concretefloor or ESD floor according to the equipment room conditions and customer requirements.

8 Installing a Cabinet

This section describes the procedure and precautions for installing a single cabinet on a base.

9 Installing the PGND Cable

The equipotential PGND cable is used to connect the PGND bolts on the cabinets to the PGNDgrounding bars on site, ensuring that the cabinets are properly grounded. The equipotential cableis used to connect the PGND bolts on the cabinets, ensuring the equipotential connectionsbetween the cabinets.

10 (Optional) Installing the Modules

The mandatory modules in the cabinet are already installed. The optional modules can beinstalled on site according to different field requirements.

11 Installing the Cables

The BTS3900 cabinet is delivered with boards installed, and the internal cables are alreadyinstalled. Therefore, only the external cables and cables for the optional modules need to beinstalled on site.

12 Installation Checklist

After the cabinets and devices are all installed, you need to check the installation items,installation environment, and cable-related items.

13 Performing the Power-On Check

Before the cabinets are put into use, you need to check the power-on status of the cabinets.

14 Obtaining the ESN

The Electronic Serial Number (ESN) is unique to a Network Element (NE) for identification.The ESN is used during the commissioning of the base station.

7 Installing the Base

About This Chapter

The BTS3900 cabinet must be installed on the base. The base can be installed on the concretefloor or ESD floor according to the equipment room conditions and customer requirements.

7.1 Installing the Base on the Concrete FloorThis section describes the procedure and precautions for installing the base on the concrete floor.

7.2 Installing the Base on the ESD FloorThis section describes the procedure and precautions for installing the base on the ESD floor.

7.1 Installing the Base on the Concrete FloorThis section describes the procedure and precautions for installing the base on the concrete floor.

ProcedureStep 1 Determine the position of the cabinet by referring to the marking template, as shown in Figure

7-1.

1. Use the percussion drill with bit 16 to drill holes at the anchor points, and ensure that the

depth of each hole ranges from 52 mm to 60 mm.

7 Installing the BaseBTS3900 LTE

Installation Guide


Issue 02 (2010-07-30)

WARNINGTake proper safety measures to protect your eyes and respiratory tract against the dustbefore drilling holes.

2. Use a vacuum cleaner to clear the dust inside and around the holes. If the inter-hole spacingis too wide or too narrow, locate and drill holes again.

3. Slightly tighten the expansion bolt, and then put the expansion bolt assembly into the holevertically.

4. Use a rubber mallet to hammer the expansion bolt until the expansion tube is buried intothe hole.

5. Remove the M12x60 bolt, spring washer, and flat washer from each expansion boltassembly in sequence.

WARNINGAfter disassembling the expansion bolt assembly, ensure that the top of the expansion tubeis on the same level as the floor.

Step 3 Install the base and adjust the base level.1. Place the insulating spacer and the base on the floor, align the mounting holes in the base

and in the insulating spacers with the holes of the expansion bolts in the floor, and then usefour M12x60 bolts to secure the base, as shown in Figure 7-3.

7.2 Installing the Base on the ESD FloorThis section describes the procedure and precautions for installing the base on the ESD floor.

ContextFigure 7-6 shows the support for installing the ESD floor.

Figure 7-6 Support for installing the ESD floor

(1) Mounting holes for the ESD floor (2) Frames (3) Mounting hole for the concretefloor

The support for installing the ESD floor on which the cabinet is installed is classified into twotypes: support with fixed height and support with adjustable height. Table 7-1 lists the relationsbetween the two types of supports and the height of the ESD floor.

Table 7-1 Height of the support for installing the ESD floor

Type of the Support Height of the ESD Floor (Unit: mm)

Support with fixed height 296 to 495

Support with adjustableheight

120 at least; adjustable according to the height of the floor



7-5

NOTE

Height of the ESD floor refers to the spacing between the concrete floor and the upper surface of the ESDfloor.

Procedure

Step 1 Determine the installation position of the cabinet on the ESD floor by referring to Installing theCabinet on the Concrete Floor Step 1.

Step 2 Drill holes on the ESD floor.1. Use a percussion drill with bit 16 to drill holes at the anchor points. The holes should

penetrate the ESD floor, as shown in Figure 7-7.

Figure 7-7 Drilling a hole on the ESD floor

WARNINGTake proper safety measures to protect your eyes and respiratory tract against the dustbefore drilling holes.

2. Use a vacuum cleaner to clear the dust inside and around the holes. If the inter-hole spacingis too wide or too narrow, locate and drill holes again.

Step 3 Position the support.1. Place the support under the ESD floor, and then use bolts to secure the ESD floor on the

support temporarily, as shown in Figure 7-8.

Installation Guide


Issue 02 (2010-07-30)

l The PGND cables for the base station must be connected to the same ground bar.
