All cables shall be of sufficient length to enable termination at the LAN Ethernet drop boxes and reach their respective racks within the LAN Equipment Room plus 2 m (6.6 ft.) at each end .

The network systems shall utilize multi-mode fiber optic backbone between the servers and backbone switches to be furnished and installed by the Government, however, the Contractor shall propose suggested locations for remote switches. The Government will terminate all cables within the LAN Equipment Room and at remote switching devices and the Contractor shall terminate all cables at LAN Ethernet drop boxes after compartment completion.

The Contractor shall install non-metallic cable bands for identification on all network cabling, which meet or exceed the operating and environmental requirements of the cable on which it is used. Cable band material shall be compatible with the cable jacket material on which it is used. The cable bands shall be either black or white. All cable band characters shall be legible, permanently stamped and visible to read without interference. The thickness of cable bands shall be no less than 0.010 inches.

402 Secure Electronic Information Processing Systems Construction of secure spaces and installation of secure inter-compartment cables shall be in accordance with IA PUB Module 5239-22 and Module 5239-31, and exhibit 10a of SECNAV M-5510.36. The physical perimeter barrier of a secure space shall be the deck, overhead, and the bulkheads that bound the space. Secure cables that pass through Uncontrolled Access Area (UAA) spaces shall be installed in a hardened carrier as defined by IA PUB Module 5239 22.

Spaces shall be designated as Secure Room (SR), Restricted Access Area (RAA) or UAA as defined by IA PUB Module 5239-31 as follows:

a) SR:

1. LAN Equipment Room

b) RAA:

3. SO Office

Doors for secure spaces shall be provided with an X-10 Combination Lock.

403 Personnel Safety Personnel shall be warned of potential hazards in accordance with the following:

a) Electrical Shock - A label plate relating to circuit disablement shall be inscribed as follows and shall be affixed, with pertinent information filled in, on all equipment energized from multiple power sources:

WARNING

THIS EQUIPMENT ENERGIZED FROM MULTIPLE SOURCES

TURN OFF THE FOLLOWING TO FULLY DE-ENERGIZE THIS UNIT

405 Grounding and Bonding Shipboard bonding, grounding, and other techniques for electromagnetic compatibility and safety shall be in accordance with Military Standard MIL-STD-1310 unless specified otherwise.

407 Electromagnetic Environment Effects (E3) Cables routed internal to the YRBM craft shall not be routed within 31 cm (12 inches) of weather openings such as doorways, hatchways, and window openings unless the cables have a single or double optimized braid shield or the cables terminate at these openings, such as door alarm cables.

The YRBM crew shall not be exposed to unsafe levels of electromagnetic radiation anywhere on the craft. Equipment arrangement and installation methods shall prevent performance degradation from Electromagnetic Interference.

The YRBM shall be provided lightning protection systems. The lightning protection system shall meet MIL-STD-464 and MIL-STD-1310. A separate 0000 AWG cable connected to the main ground connection point shall be installed for lightning protection. This cable shall be routed in as straight a line as possible and shall be continuous and unspliced from the highest conductive surface to the main ground connection point. Where a metal mast is used, it shall be connected to the ground plates using a size 0000 AWG cable. Equipment on the mast that requires grounding shall be grounded to the mast.

422 Electrical Navigation Aids The YRBM craft shall be provided with navigation lighting in accordance with Department of Homeland Security, USCG Navigation Rules and Regulations Handbook for a moored barge and barge being towed, unmanned, in open-ocean and coastal environments.

Navigation lights and their connected batteries shall be capable of a minimum of eighteen (18) hours of continuous operation without recharging.
