Note
1Overview of field upgrade
This document provides instructions for upgrading an existing Nokia MetroSite
BTS installation. Field upgrades are done for the following reasons:
• Upgrade of TRXs from GSM to GSM/EDGE transmission (including
upgrade from 1W TRXs, if relevant).
• Upgrade of BTS capacity by chaining to include up to 12 TRXs.
This chapter describes the upgrade options in more detail and the working order
for the upgrade procedures.
1.1 GSM to GSM/EDGE upgrade
A GSM MetroSite BTS installation is upgraded to EDGE transmission by
replacing the GSM TRX units with 5W GSM/EDGE TRXs or by adding 5W
GSM/EDGE TRXs to any spare TRX slots in the BTS.
A software upgrade to CX 3.0 or later is also required for upgrade to EDGE. This
is done locally at the BTS during commissioning with Nokia BTS Manager.
With the 5W GSM/EDGE TRXs, MetroSite can operate with either GSM or
EDGE transmission.
If the MetroSite BTS still contains 1W TRXs, a higher capacity cooling fan and
a different power supply unit must also be fitted to the BTS when the TRXs are
upgraded to 5W GSM/EDGE TRXs.
1.1.1 Working order for GSM/EDGE upgrade
The procedures to be completed and the working order in which they are done are
presented below.

Note
2Preparing for upgrade
Before starting any upgrade procedures, the procedures and precautions presented
in this chapter should be read and implemented as required.
Some of the upgrade procedures require the BTS to be powered down. Read
Section 2.1, Power supply precautions, in this chapter before beginning the
upgrade.
2.1 Power supply precautions
Potentially lethal voltages!
The BTS power must be switched OFF at the main disconnect device or
circuit breaker before starting maintenance work which involves the risk of
electric shocks.
Prevent injury to personnel or damage to the BTS equipment by following the
power supply rules for maintenance and upgrade procedures presented in Table .
The switch on the power supply unit (PSU) of the BTS has two positions: ON and
Stand-by.

Note
• One or two Nokia MetroSite EDGE BTS base stations with GSM/EDGE
TRXs but without transmission units (depending on the number of slave
BTS cabinets planned).
The BTS cabinets will need to be installed as described in the document, Nokia
MetroSite EDGE Base Station: Installation. The parts required for BTS
installation are listed in that document.
• One or two Nokia MetroSite BTS extension cable kits (depending on the
number of slave BTS cabinets planned). The kits contain a cable and a
termination connector. There are three different lengths of extension cable,
as follows:
• extension cable kit, 3 metres (part 467614A)
• long extension cable kit, 5 metres (part 469585A)
• short extension cable kit, 1 metre (part 469584A)
• Nokia SiteWizard with CX 3.0 software or later, and including Nokia BTS
Manager 3.0 or later.
2.4 Checking the site for an upgrade
Before beginning the upgrade, the site should be checked by the site supervisor.
The site should be checked against a site preparation checklist and confirmed as
correct according to the site drawings and plans.
The BTS site should be readily prepared according to the specifications given in
Nokia MetroSite EDGE Base Station: Requirements for Installation and
Operation. In the case of a BTS chaining upgrade, the extra BTS cabinets should
be already installed and checked.
If the site does not meet the requirements in the checklist, complete the site
deficiency reports and report to the Installation Manager / Site Manager before
continuing with the upgrade.
2.4.1 Checking environmental conditions on the site
Check the site conditions before starting the upgrade procedures. In the case of
precipitation (rain, snow or sleet), the site must be weather-guarded during the
upgrading procedure to prevent damage to the units when the BTS cover is
removed. Note the following:

Caution
Removing the BTS cover
1. Unlock the cabinet lock at the bottom of the BTS.
2. Remove the cover by sliding it upwards to disengage the hooks at the side
of the cover from the locking guides on the BTS chassis.
3. When the cover is free, pull it away from the cabinet and hang it on the
hook at the top left side of the chassis.
You can also remove the cover completely to place it on the floor. Remove
the safety strap before pulling the cover away (see Figure 14).
2.7 ESD protection
Some units in the MetroSite BTS contain electro-static sensitive devices. The
BTS is labelled with an electro-static sensitive device symbol as shown in Figure
1.
Always use an anti-static wrist strap connected to the cabinet ESD stud, whenever
handling electro-static sensitive units. The wrist strap and connection stud is
shown in Figure 2.
