Installing a PIC

This section describes the procedure for installing a PIC. You should also follow this procedure, in particular the safety procedures and warnings, when replacing or removing a PIC.

Caution You cannot install PICs into an AT-AR040 NSM that has power applied to it. This includes NSMs that have been deactivated using the hot swap button, but not physically removed from the switch or router. To ensure that all power is removed from the NSM bay, you must either physically remove it from the switch or router using the hot swap method, or disconnect all power sources to the switch or router.

1.Read the safety information.

For safety information, see the Installation and Safety Guide shipped with your switch or router. You can also download the complete documentation for your switch or router from www.alliedtelesis.com/support/software/.

2.Gather the tools and equipment you will need.

A medium-sized flat-bladed screwdriver may be useful when loosening the PIC thumbscrews. You should also have any cables required for connecting the PIC to a wide area network or other network devices.

3.Remove power to the switch or router.

Warning Do not install a PIC into an NSM bay or PIC bay base unit without first removing power from the switch or router. Be sure to disconnect both the main power supply and any attached redundant power supply. Installing a PIC with the switch or router powered ON can damage the PIC, NSM and base unit.

4.Remove all TNV connections to existing PICs.

Warning Remove any cables attached to the external WAN ports of the AT-AR020, AT-AR021 and AT-AR027 PICs, as these supply TNV into the switch or router. Dangerous voltages may be present on some parts of the board, even if the switch or router is powered OFF.

5.Install the AT-AR040 NSM if required.

Use the installation instructions in the Network Service Module Installation and Safety Guide to install an AT-AR040 NSM.

6.Remove the PIC bay faceplate, NSM PIC bay faceplate, or existing PIC.

Loosen the thumbscrews to remove the faceplate or PIC. Keep the faceplate for future use. If you remove the PIC, replace the faceplate to prevent dust and debris from entering the switch or router and to maintain proper airflow.

The AT-AR021 (U) BRI-U is primarily designed for digital telephony applications, featuring two BRI (Basic Rate Interface) ports. This enables organizations to efficiently connect to ISDN lines, facilitating reliable voice communications. It supports a variety of protocols, ensuring compatibility with numerous telecom networks, which is essential for businesses relying on seamless voice integration.

The AT-AR022 ETH is a versatile solution that focuses on enhanced Ethernet connectivity. Designed for high-speed data transmission, it supports multiple VLANs (Virtual Local Area Networks) and Quality of Service (QoS) configurations. This ensures that critical applications receive the bandwidth they need while providing efficient network traffic management.

For organizations requiring enhanced Ethernet capabilities, the AT-AR026 4ETH offers four Ethernet ports, providing flexibility for multiple devices to connect simultaneously. This model is particularly beneficial for small to medium-sized enterprises looking to develop a robust local area network (LAN) without extensive infrastructural changes. Its ability to support power over Ethernet (PoE) enables it to power devices like VoIP phones and security cameras directly through the network cable, simplifying deployment and reducing clutter.

The AT-AR023 SYN model is tailored for synchronous communication, making it ideal for applications that demand constant data flow and real-time processing. Its advanced synchronization technology ensures minimal latency and maximum throughput, critical for industries such as finance and telecommunications, where precise timing is essential for operations.

Finally, the AT-AR024 ASYN4 caters to asynchronous communication applications. This device supports four asynchronous serial ports, enabling connectivity with a wide range of equipment, including legacy systems, smart devices, and industrial machinery. It serves as a bridge for organizations transitioning from traditional systems to modern networking paradigms.

In summary, Allied Telesis offers a diverse portfolio of networking solutions through the AT-AR021 (U) BRI-U, AT-AR022 ETH, AT-AR026 4ETH, AT-AR023 SYN, and AT-AR024 ASYN4. Each model embodies unique features and technologies designed to enhance connectivity, ensure compatibility, and facilitate seamless communication across various platforms, making them essential components for contemporary network infrastructures.
