![]() The rest of the network analysis tools can be used alone or in combination for network discovery. ![]() Hardware troubleshooting with built-in FortiOS hardware diagnostic commands. Five of the tools in our list ( ping, tracert, ipconfig, netstat, & nslookup) can be executed directly from a Windows command prompt (cmd.exe) without installing any additional programs for advanced troubleshooting. This phenomenon is normal.įortinet does not include this cable in the product box. The LED will only start to blink during the 'Network Interface Detection' test. If it is necessary to plug a self-loopback cable during the HQIP test, make sure to use a cable with the technical specifications above. ĭo you want to continue this test? (y/n) (default is n) y Network Interface Loopback Test - Please connect ethernet cables: LampA lamp is equipped in main unit, helps work in darkness. It’s designed just for cable qualification, can test Ethernet and coax runs but has no fiber. Loopback TestingTest the loop circuit connected to switch is normal or not. Brown and Blue ones are used for other purposesĭuring HQIP Tests, it may be required to plug a 'SELF-LOOPBACK' into interfaces so they can be tested, and in the example below, the HA port should receive a self-loopback cable while the other ports should be plugged into each other as described. The Fluke Networks CIQ-100 is the most basic tester and least expensive of the three we reviewed.Green and Green/White are often used to transmit data and may be often referred to as receive pair.You may have to register before you can post: click the register link above to proceed. Orange and Orange/White are often used to transmit data and may be referred to as transmit pairs.

The Self-loopback cable is a special wired cable where the TX lane and RX lanes are 'looped' as illustrated below: Loop detection guard is a new way to prevent loops with both STP and non-STP enabled ports or unmanaged switches. The details below should help to use the proper cable. This article provides some technical specs on the 'Self-Loopback' cable mentioned in HQIP hardware tests. Remove the jacket of CAT5/6 Cable and cut out one pair (2 Wires) of approx. ![]()
