 For Thin Ethernet (Cheapernet, IEEE 802.3, 10 base 2) systems use ESP ThinNet.
 For Thick Ethernet (IEEE 802.3, 10 base 5) systems use ESP ThickNet.

To protect twisted pair Ethernet (10 or 100 base T) networks with RJ45 connections use ESP Net-100.

Application

Use these protectors on thick and thin Ethernet cables to protect:

 computers
 transceivers
 servers
 repeaters
 other network equipment

Features and benefits

  Let-through voltage below equipment susceptibility levels to ensure effective protection for your equipment.

  Protection between all sets of conductors to close all transient paths to equipment (see Ethernet technical note ).

  Provides repeated protection - even in lightning intense environments.

  Very low reflection coefficient/VSWR ensures that the Lightning Barrier doesn t disrupt network operations.

  High bandwidth to prevent the degradation of high frequency signals.

  Low in-line resistance to minimise unnecessary reductions in signal strength and maximise signalling distance.

  Robust steel housing.

  Convenient holes for flat mounting.

  Substantial earth stud to enable effective earthing.

  Easy installation .

  Straightforward and comprehensive installation instructions .

  5 year warranty.

Installation

Connect in-line with the Ethernet cable near to where it enters/leaves the building or close to the equipment being protected. This should be close to the system s earth star point (to enable a good connection to earth). Install either within an existing cabinet/cubicle or in a suitable enclosure. If installing two or more protectors together these can be simultaneously mounted and earthed via a CME kit.

Note: allowing for one protector at each end, ESP ThinNet can be installed on segment lengths of up to 148 metres and ESP ThickNet can be used on segment lengths of up to 400 metres.

Suitable accessories

Simultaneously mount and earth up to two ESP ThinNet or ThickNet protectors on a CME 4 or up to four on a CME 8 (see page 43). Enclosures for a single ESP Thick or ThinNet (the WBX 3/G) or for protectors on a CME 4 (the WBX 4) or CME 8 (the WBX 8) can be found on page 44.
