Abstract: An aisle containment apparatus having a pair of spaced apart upper rails and a pair of spaced apart lower rails positioned spaced apart from and below the pair of upper rails. A side blanking panel is secured to one of the pair of upper rails and to one of the pair of lower rails and a ceiling spans between the pair of upper rails. A fixed panel is secured to the pair of upper rails and to the pair of lower rails and a moveable panel is releasably secured to the pair of upper rails and is adjustably positioned along the pair of upper rails so as to position the moveable panel a predetermined distance from the first panel.

Abstract: The aisle containment system is mounted to two rows of equal width cabinets or cabinets varying in width between 600 mm, 700 mm and 800 mm. The aisle containment system includes door assemblies on both ends of the cabinet rows, vertical panels that mount to the cabinets and door frames to support the ceiling, cross tees that span the aisle, and ceiling panels. Additional cabinets of equal or varying width may be added to an aisle containment installation.

Abstract: A device for providing transient voltage suppression on a Power over Ethernet system is provided. The device includes a transient voltage suppression module. The transient voltage suppression module includes a circuit module, which includes a circuit board and input and output connectors. One or more transient voltage suppression modules may be mounted to a frame to form a transient voltage suppression patch panel, which, in turn, may be mounted to a rack for use in a telecommunications room. The circuit board combines a frequency-variable impedance connected between conductors in a pair and a voltage-variable impedance connected to the frequency-variable impedance, where the voltage-variable impedance is also connected to a chassis and/or an electrical ground.

Abstract: Alien crosstalk suppression cores are used to decrease alien crosstalk in communications channels. Electrical communication cables may be provided with alien crosstalk suppression cores. The alien crosstalk suppression cores, which may be ferrite suppression cores, are placed separately on some or all of the twisted pairs within a communication cable. The alien crosstalk suppression cores reduce ANEXT and AFEXT in high-frequency communications when communication cables are installed near one another. Alien crosstalk suppression cores may also be incorporated into other communication channel components, such as on a PCB within a communication jack.

Abstract: An access control system dissipates voltage transients while allowing access control equipment to operate normally. The access control system utilizes an isolation patch panel which is provided with circuitry to prevent voltage transients from damaging access control equipment, while also enabling the access control equipment to be wired with standard Ethernet cabling.
