ADTRAN TSU IQ+, 1204002L2 DBU and LAN Card Slots, Network Connector, Test Jacks, Monitor, In/Out

Chapter 2. Installation

DBU and LAN Card Slots

The TSU IQ+ rear panel has two card slots (labeled DBU Interface and LAN Interface) for the installation of dial backup, ethernet, and DCE cards. To insert cards, perform the following procedure:

1.On the rear panel, turn off the power switch.

2.Slide the card into the corresponding rear slot until the card panel is flush with the TSU IQ+ chassis.

3.Push card locks in (until they click) to secure the card and ensure proper installation.

Card slots are keyed to prevent improper installation (i.e., putting a DBU card into the ethernet slot). The DCE card is keyed for the DBU slot.

Failure to remove power from the unit before installing or removing op- tion cards can damage the equipment.

Network Connector

Connect the TSU IQ+ to the network by using the 8-position modular jack labeled NETWORK. The pinout for this connector is listed in Pinouts on page A-1.

Test Jacks

Monitor

The monitor jack (labeled MON) is used as a non-intrusive monitoring point for the data received from the network. The monitoring device needs to be set for high impedance bridge mode.

In/Out

The IN and OUT jacks are used to connect to a T1 test set for testing the T1 interface of the TSU IQ+. These connections isolate the T1 interface from the RJ-45 network jack.
