  • Page 10: Introduction To Ux400

    VeEX® UX400 is the industry’s most flexible, compact, and future-proof test solution for OTN, SDH, SONET, PDH, T-Carrier, Carrier Ethernet, Mobile Backhaul, Core, and Storage Area Networks. VeEX UX400 is the first truly robust portable platform to offer test capabilities ranging from DS1/E1 to 100GE and beyond, allowing any combination of test modules tailored for each particular application or set of requirements.

  • Page 11: Safety Information

    Optical Connectors The UX400 displays a laser warning icon when the laser source is active to alert the user about a potentially dangerous situation. It is recommended to: 1. Deactivate the laser before connecting or disconnecting optical cables or patchcords.
  • Page 12 UX400 battery pack is also fitted with a safety connector to prevent accidental short circuits and reverse polarity. Always charge the UX400 battery pack inside the UX400 battery bay using the UX400 AC/DC adapter supplied by VeEX. Do not charge or use the battery pack if any mechanical damage is suspected (shock, impact, puncture, crack, etc).

  • Page 15: Using The Built-In Battery Backup System

    - If the UX400 is being used while charging and a full charge (100% capacity) can not be achieved within three hours, the charging will automatically stop. - To resume charging, unplug the AC/DC adapter and let the UX400 work on battery power for a minute or two and plug the AC/DC back in. This would reset the charging circuity.

  • Page 16: Battery Overdraw Protection

    Inactive modules (not assigned to a test application) do not consume power. When working on battery-only mode, the UX400 notifies users when the maximum battery capacity has been reached or it is not enough to support the new module user is trying to activate.

The RFC 2544 test suite consists of and performs a set of four automated tests (throughput, latency, frame loss, and burst or back-to-back) to qualify the performance of a network link under test. The tests are especially popular for the verification of network links with certain service level agreements (SLA).
