GENERAL INFORMATION

1. IMPORTANT! In the event the GX is:

• Modied or altered by any party other than Corning; or

• Subjected to misuse or improper handling or installation;

Corning’s product warranty will be void and no longer valid. This includes replacing or removing connectors in

the eld during installation.

2. In both indoor and outdoor applications, the GX unit should be mounted vertically with the connectors facing
upwards/downwards.

IMPORTANT! If the GX is mounted horizontally in an indoor application, sufficient cooling must be ensured

(i.e., air conditioning) and a sufficient tethering harness is required.

3. IMPORTANT! OptiTap® adapter pullout force ranges from a few lb to 50+ lb with the dust cap or connector installed.
This prevents damages caused to the DAS unit.

4. For deployments with the Corning® optical network evolution (ONE™) solution, the following additional elements
are required (ordered separately):

• Optical central hub (OCH-4-WDM/OCH-8-WDM) – performs the RF-to-optical conversion of the service signal

• ERFCv2-OCH cable – extender cable interfacing to the HEU RIX module and the OCH

• SC-450 unit – system controller required for GX management

5. For GX models supporting the CELL band – an external lter is required (ordered separately) if GX remote is deployed
along with 800 MHz band MA1000/MA2000 units. Filter to be installed before GX mounting.

6. Two people are required for mounting – unit weight: 154 lb (70 kg)

7. Wooden pole mount option accessory kit (AK-GX-QUAD-BRKT-WDPOLE) is available (ordered separately). Instructions
are provided with the kit.

8. Two additional options are available (ordered separately) for performing the GX RF antenna connections:

• Via the GX 4 x 1 External Multiplexer (P/N: AK-GX-ECPL-COMB) – RF antenna connections are performed via the

service specic GX external multiplexer

• Via GX couplers (P/N: AK-3COUPLER-DM-DF) – ensures that users/eld engineers can measure and read signals

without interrupting service due to service cable disconnections
