    4U Corner Wall Mount Cabinet

    If your office feels a bit cramped but your company is not ready to take the plunge into a bigger floor plan, it might be time to further maximize the space you have. The thought of squeezing more usable square footage out of already-small confines such as server rooms, telecom closets, or retail spaces may seem daunting. But there’s a smart solution that’s relatively inexpensive: wall-mounted equipment cabinets.

    This blog post describes two big benefits of wall-mounted cabinets and concludes with some details about ShowMeCables’ large selection of them.

    Wall-mounted cabinets offer most of the benefits of floor cabinets – they’re rugged, secure, come in many sizes, and have pro features like built-in fans, locking front and side doors, and a front panel of tempered glass for monitoring rack components.

    Freeing Up Floor Space

    A few benefits make wall cabinets unique. First, they don’t hog floor space. Install one or two in place of a floor cabinet and you’ll marvel at how much bigger the room suddenly seems. Or keep the floor unit in place and use the wall cabinet for new components that improve your capabilities.

    Using Vertical Wall-Mounted Cabinets

    Second, you can install wall-mount cabinets in your previously unused vertical spaces. ShowMeCables offers 50+ different vertical wall-mount enclosures that position components sideways to take up less space. For instance, our 2U vertical enclosure extends only 4.5 inches from the wall. Such a low-profile enclosure can fit just about anywhere, from hallways to retail spaces to cramped IT

  2. RJ11 to RJ45 Wiring Diagram

    Adapting an RJ11 to an RJ45 Cable: A Practical Guide

     

    Using an RJ11 to RJ45 wiring diagram is the best way to convert from the 8-positon RJ45 to a 6-position RJ11 connector. In today's rapidly evolving technological landscape, the need to adapt and repurpose existing equipment is becoming increasingly common. In this blog post, we will explore the steps required to successfully adapt an RJ11 to an RJ45 cable.

     

    Before diving into the adaptation process, it is crucial to understand the fundamental difference between an RJ11 and an RJ45 connection. RJ11 cables are commonly used for telephone connections and have six positions and four contacts. RJ45 cables are primarily used for Ethernet connections and consist of eight positions and eight contacts. Adapting an RJ11 to an RJ45 cable allows you to repurpose telephone lines for Ethernet connectivity, thus maximizing the utility of existing infrastructure.

     

    An RJ45 to RJ11 converter cable is designed to connect your RJ11 devices such as analog phones, answering machines, fax machines etc. through a VoIP RJ45 Ethernet port.

     

    Since the RJ11 only uses four wires, it will only work with 10/100 Ethernet. 1 Gigabit Ethernet requires the use of eight wires or leads.

    Looking at the top of the RJ45 connector (the clip is facing down) you can see the pin reference for both T-568A and T-568B wiring schemes. With T-568A and T-568B the pin locations stay the same, but the wire color location scheme is different.

  3. DB9 Connector Pinout

    When building or repairing DB9 cable assemblies many customers request a DB9 connector pinout reference drawing in order to determine where each conductor of the cable should be terminated to. There are several primary types of DB9 connector pinout schemes that we will review in  blog post.

    DB9 Connector Pin Locations

    First, we will take a look at the DB9 connector pin locations for a male and female DB9 connector. Note the orientation of the connector where the short side of the shell is located on the bottom and the longer side is on the top.

    DB9 Connector Pinout

    There are several DB9 connector Pinout schemes to address different standards and technologies. Here we take a look at two of the predominantly used configurations.

     

    DB9 connectors used for RS232 communications

    DB9 connectors have long been used in serial communications to attach peripherals to PCs. With the advent of USB connectors, DB9 is no longer the connector of choice for this function but there are still legacy devices using DB9 connectors for RS232 connectivity.

    Floor-mounted rack or wall-mounted rack? It’s a key consideration when you shop for a rack for your IT networking equipment. The obvious benefit of wall-mounted models is that they don’t take up floor space in small rooms. But space isn’t everything.

    Below we list six solid advantages of floor-mounted racks, also known as free-standing racks. We conclude with a summary of ShowMeCables’ floor-mounted offerings.

    Advantages of Floor-Mounted Racks

    • Increased Weight Capacity: Floor-mounted racks are typically designed to support heavier equipment and larger network setups. They can accommodate a higher weight capacity compared to wall-mounted racks, making them suitable for larger networks with multiple servers, switches, and other network devices.
    • Enhanced Stability: Floor-mounted racks are more stable and less prone to movement or vibrations compared to wall-mounted racks. This stability is especially important for delicate or sensitive equipment that may be affected by excessive movement.
    • Improved Accessibility: With a floor-mounted rack, you have easier access to the front and rear of the equipment. This facilitates equipment installation, maintenance, and cable management. You can easily reach the devices from all sides, making it more convenient to manage and troubleshoot the network infrastructure.
    • Greater Flexibility: Floor-mounted racks, especially those on caster wheels, offer more flexibility in terms of equipment placement and expansion. You have the freedom to position the rack wherever needed in the room, allowing for better utilization of space. Also, floor-mounted racks can be extended or modified to accommodate future

    Basics of HDMI AV Cables

    HDMI stands for High-Definition Multimedia Interface. It is an industry-standard audio/video interface that provides digital signals between a source device—such as a Blu-ray player or video game console—and a display monitor or television.

    HDMI AV cables are designed to transmit audio and video data in high-definition quality with minimal loss of signal strength.

    HDMI AV Cable Types

    There are three main types of HDMI cables: passive, active, and optical, depending on their circuitry and optimal distance.

    1. Passive HDMI cables transfer the signal from the source to the display without additional circuitry. These cables are bi-directional, meaning you can connect either end to an HDMI input or output. Passive HDMI cables are suitable for cable lengths up to 15 feet and provide a stable signal.
    2. Active HDMI cables contain amplification circuitry in one of the connector heads. Some active HDMI cables require an external power source to operate the amplification circuitry, while others have an internal power supply.
