Once the power is on at the host system, the SQE LED will be lit on each 
transceiver that has the heartbeat feature enabled. Conversely, the LED 
is not lit on the transceivers with the heartbeat disabled.

 

Caution: 

 

Earlier transceiver models used a jumper for this setting. 

 

Do 

not

 

 install a jumper to enable SQE. Damage can result if a jumper is 

installed in a transceiver equipped with an SQE switch.

Installing the Transceiver Tap

 

There are three types of taps that can be installed in the transceiver. To 
install the transceiver tap, proceed to the appropriate transceiver tap in-
stallation instructions, as follows: 

For ST-500-01 transceivers, go to Section 2.5.1.

For ST-500-02 and ST-500-03 transceivers, go to 
Section 2.5.2.

 

2.5.1

Installing the ST-500-01 Transceiver Tap

 

To install the tap, proceed as follows:

1.

Open the 1K-TAP-01, Installation Kit (Figure 2-2) and check that it 
contains the following:

• Cable Bed

• Center Probe

• Clamp

• Pressure Screw

• Braid picks (2)

• Hex Wrench
