INSTALLATION GUIDE: 1000BT-AT+7C Network Tap

The 1000BT-AT+7C is a non-aggregating network TAP designed for in-line use in 1000BaseT Copper

Gigabit production links. The tapping is non-intrusive and the tapped links will operate at line rate with no

measurable latency. Endpoint devices of the tapped links may be 10/100/1000 Auto operating at 1000

Mbps or 1000 Fixed.

It may NOT be used in 100BaseT links or in links configured to operate at 100 Fixed.

The non-aggregating design provides separate copies of the Rx and Tx traffic thus ensuring that all

packet copies are delivered to the monitoring tools – there is no potential for internal oversubscription.

Up to seven (7) tools may be attached and should be capable of receiving both Rx and Tx data copies.

This is a non-managed device. There is no operating system, management port or software. The user

cannot assign an IP address – it is necessary only to connect the cabling and the power supplies.

The TAP consists of two units – A and B – which are connected together via fiber ports. Unit A contains

the copper Gigabit tap assembly and the first three sets of Monitor ports. Unit B contains the remaining

four sets of Monitor ports.

The data path for both the Rx and Tx copies between the Unit A and Unit B is provided by means of two

short SX (multi-mode) fiber jumpers which are included with the device. If these fiber pairs are ever

replaced it is mandatory that 62.5 micron SX multi-mode fiber be used. Connectivity must be from "A Out"

of the A unit to "A In" of the B unit and from "B Out" of the A unit to "B In" of the B unit.

CONNECTING THE LINK

1. Install assembly in rack – do not connect power supplies initially

2. Disconnect the existing Cat 5 or higher cable from one of the endpoint devices of the link to be

tapped. Reconnect that cable to the Network A Port.

3. Connect the remaining endpoint device to the Network B port using an additional Cat 5 or higher

cable of appropriate length.

4. Check the two endpoint device to verify that they have established link with one another through the

unpowered tap. If link has not been established then reverse the position of the connections on

Network A and B. The cable end presently connected to Network A should be moved to Network B

and vice versa. Do not change the cable connections where they connect to the endpoint devices.

VERIFYING POWER FAULT TOLERANCE

2.1 Connect the four power supplies. They are load sharing devices and although only one power supply

is required for unit A and one for Unit B it is suggested for highest reliability to use all four and

connect to two separate AC grids per unit. The power indicators labeled 1 and 2 on front panels of

both units should be illuminated if power supplies are functional and properly connected.
