Spare Channel Replacement Procedure

Spare Channel Replacement Procedure

C A U T I O N

This procedure is included so the instrument can be repaired quickly in the
field. Performing this procedure violates the calibration seal. When spare fibers
have replaced bad port fibers, the unit should be sent to an Agilent
Technologies Service Center, at your earliest convenience, to have new port
fiber/connectors spliced into the instrument and to have the instrument
calibrated.

1

Disconnect the power cord from the instrument.

2

Remove the top cover using a #15 or #20 TORX driver.

3

Locate out the spare cable/connector. Refer to

Figure 5-1 on page 5-5

and

Figure 5-2 on page 5-6

. The spare cable/connector is on the bottom of the

switch assembly, secured with a tie-wrap. Remove the tie-wrap.

Switches with 50 channels or less have one spare fiber. Switches with more
than 50 channels have two spare fibers, labeled S1 and S2.

4

Replace the defective port cable/connector assembly with the spare assembly.
Note the label on the spare cable/connector and record the identification
number (S1 or S2) for use later on in this procedure.

5

Replace the top cover.

6

Connect the power cord to the instrument. Turn the instrument on.

7

Press

Help

, then enter the model number of the lightwave switch from the

keypad: 86060, 86061, or 86062.

8

Press the

4 key

.

9

Perform this step

only

if the lightwave switch has multiple layers. Determine if

the lightwave switch has multiple switch layers installed. (A switch layer is a
switch matrix of “A” ports and “B” ports. Normal lightwave switches have only
one layer installed.) If the rear panel shows more than one set of “A” ports and
“B” ports, the instrument has multiple switch layers. The display will prompt
