Overview This chapter describes how to mount the ERAM-A Remote Aggregator in 600 mm equipment racks.

3.2

Environmental and mounting constraints This section describes site requirements for the ERAM-A Remote Aggregator and provides information about:

• environmental and mounting requirements • airflow for the ERAM-A Remote Aggregator

Environmental and m ounting requirements Ensure that the environmental conditions meet GR-63-CORE. The following is a list of environmental and mounting requirements for an ERAM-A Remote Aggregator:

• The minimum cooling airflow for an ERAM-A Remote Aggregator mounted

•

• • •

horizontally in a Central Office (CO) or Controlled Environment Vault (CEV) is 0.7 m3/min with a 25 PPI air filter installed. In accordance with GR-3028-CORE, airflow direction is (S) SL-SR when mounted horizontally. The minimum cooling airflow for an ERAM-A Remote Aggregator mounted in an OSP cabinet is 1.1 m3/min with no air filter installed. Only vertical deployments are supported. In accordance with GR-3028-CORE, airflow direction is bottom inlet top exhaust). The maximum electrical power consumption and thermal dissipation capacity is 80 W, 2 A at 40 V (two 5 A fuses, field replaceable) for the ERAM-A Remote Aggregator. To prevent the ERAM-A Remote Aggregator from overheating, avoid installing the shelf adjacent to any other equipment that exhausts or takes in cooling air. Any ERAM-A Remote Aggregator deployments in closed cabinets must be in GR-487 or GR-3108-CORE Class 2 cabinets, where the cabinets provide maximum 65 C inlet air to the shelf fans at a cabinet external ambient temperature of 46 C, and full solar loading including any preheating of cabinet airflow by other equipment. Closed cabinets are not recommended for ERAM-A Remote Aggregator deployments in COs, only open relay racks. If closed cabinets must be used, the cabinets must provide a maximum 50 C inlet air to the shelf fans at a CO external ambient temperature of 50 C at 1800 m altitude (GR-63 CO conditions). The cabinet must not restrict shelf airflow or add temperature rise above GR-63 CO conditions, including a preheating of cabinet airflow by other equipment. The use of fan filters in the fan unit of the ERAM-A Remote Aggregator depends on the installation location: °

•

°

°

°

•

• In CO and CEV deployments, the fan unit of the ERAM-A Remote Aggregator should

•

10 / 48

be operated with a fan filter installed. These filters must be changed every three months or sooner, depending on conditions; otherwise, overheating and thermal failure may result. Use only new, Alcatel-Lucent approved fan filters. In OSP cabinets deployments, the shelf fan unit must be operated without fan filters; otherwise, overheating and thermal failure may result.

Released



• The intake and exhaust of all shelf mounting configurations must not contain any

•

obstructions caused by cabinet mounting hardware, rack hardware, or other electronic equipment in the areas shown in Figure 3-1. The intake and exhaust should not obstruct or interfere with shelf-level airflows so that bulk airflows drop below the minimum cooling airflow for the shelf. Avoid operating the ERAM-A Remote Aggregator with its fan unit removed or non-operational; overheating or thermal failure will result if the shelf is operated too long without a fan unit installed. Warning — When used in the vertical mounting orientation, the

ERAM-A Remote Aggregator or shelves must be mounted above concrete or some other non-combustible surface.

Procedure 4-5 Connecting an optical cable Use this procedure to install an SFP or XFP optical module and connect an optical cable.

Danger — Risk of eye damage or skin burns by laser emission. When installing optical boards or handling optical fibers, never look inside connectors of boards or fibers when these are not connected. Put end caps on open connectors to protect against unexpected emission.

Warning 1 — Units contain ESD-sensitive devices. These devices are susceptible to ESD damage in unconnected circuit conditions. Appropriate ESD procedures should always be followed when installing or removing units and cables. Warning 2 — Verify that cables are secure after they have been c onnected. Caution — Avoid sharp bends in cables. Use the proper bend radius when installing cables. Pinching of optical cables may cause service interruption and damage the cables. Improper placement can cause the cables to crimp and become damaged. Verify that cables are secure. Properly dress optical cables to ensure that:

• cables are not twisted or kinked • cables do not cross over the insertion and extraction tabs on top of the unit; rather, they pass to the side of the tabs 1

Put on the antistatic wrist strap and connect it to a grounding point. See the 7330 FTTN ISAM Safety Manual for more information about ESD measures.
