1.Installing the T1 Modem Bank into the rack requires two people since the T1 Modem Bank is heavy. Note that handles are provided on the T1 Modem Bank to aid in rack installation. They are part of the chassis and are located on the front of the T1 Modem Bank near the outer edges of the chassis. As one person holds the chassis in the appropriate location in the rack, the other person must ensure that all the oval slots on the rack-mounting brackets line up with the correct holes in the rack before fastening the chassis to the rack with the screws provided. Tighten all the screws with a screwdriver.

2.Repeat step 1 to install other T1 Modem Bank units in the rack.

3.Plug the power cord of each T1 Modem Bank into an outlet.

4.Insert the RJ-45 plug from the T1 line cable into the T1 jack on the Line card faceplate for each T1 Modem Bank and label the cable. (See Figure 7). A suggested method of labeling is to label each T1 line alphabetically, starting from the top.

5.Refer to the next section, “Daisy Chaining T1 Modem Bank Units.”
