90362-01 NetBlazer LS Installation 2-5

If the

light is on, the Netblazer has detected a telephone connection. If

the

light goes off, the connection has been lost. If the

light is on, your

NetBlazer is currently sending data. If the

light is on, your NetBlazer is

currently receiving data.

ISDN LEDs

The ISDN LEDs on the NetBlazer LS display the current status of ISDN

connections.

If the

LED is steadily on (not blinking) once the NetBlazer has completed

both booting and loading the software, your cables are all connected and you

have an active ISDN connection. If the

light is blinking, the NetBlazer is

trying to connect but a cable may be loose. If the

light is off, you are not

connected for ISDN, either because a cable is unplugged or because the

ISDN line into your site is not active.

The two

lights indicate the status of the two BRI lines into the NetBlazer.

If these lights are off, there is no data being sent or received. If these lights

are blinking, the NetBlazer is setting up a call. If the lights are steadily on,

you have a connection and data is being exchanged.

Equipment Requirements

Each NetBlazer LS model has different equipment requirements. As you

read through the following sections, keep in mind which of the two models

you have.

For both models, you need the following components for the installation:

• NetBlazer LS, AC cord, and power supply

• 25-pin female-to-female null modem adapter (14674-01)

• ISDN cable WT-MM1430-006 (used to connect the NT1 to the

NetBlazer ISDN BRI port), shipped with ISDN model only.

• Any additional cables appropriate to the systems and devices that

you are installing. Depending on your setup, you may need to order

cables from Telebit (see Appendix K, “Telebit Cables and Adapter

Pinouts”).
