Chapter 3 Installing the IGX
Making Frame Relay Connections
Making Alarm Relay Output Connections
To install an alarm relay module (ARM) card set:
Step 1 At the back of the IGX node, identify the slot where the ARI card is to reside.
Step 2 Install the ARM in the front slot and use the card extractors to help secure card.
Step 3 Install the ARI in the corresponding back slot. Use the extractor handles to help secure the card, then
tighten the captive screws by hand.
Step 4 Note that the FAIL LED on the ARM is not on. The ACTIVE LED also is not on.
Step 5 Attach a 22- or 24-gauge cable with the appropriate number of pairs to a male DB-37 connector at one
end. Typically, a 12-pair cable is adequate. Connect this cable to the DB-37 connector on the ARI and
tighten the captive screws.
See the Initial Startup of the IGX section on page 3-56 when the system is ready for power.
Setting Up the ARM Card Set
The steps that follow show how to set up an ARM card set after the physical installation is complete.
This is done from the IGX control terminal or the Cisco WAN Manager workstation. For details on each
command used, refer to the Cisco WAN Switching Command Reference.
Step 1 Verify that the node is equipped with the proper ARM front card and ARI back card by using the dspcds
command. This shows in which slot the cards are located.
Step 2 From a control terminal or a Cisco WAN Manager NMS workstation, log in to the node and enter the
addalmslot command followed by the slot number where the ARM is located. This activates the alarm
reporting from the card.
Step 3 Observe that the ACTIVE LED on the ARM card is on.
Step 4 Testing the operation of the alarm outputs requires you to create an alarm and note the resulting alarm
output. This test is easy on a node that is not connected to the network but is difficult on a node in a fully
operational network. The best time to create a major alarm in an operational network is during a low
traffic period. If you create an alarm, go to Step 5. Otherwise, end the procedure here.
Step 5 Create an alarm by disconnecting a trunk cable from the connector on a back card.
Step 6 Observe that a MAJOR LED comes on on the front of the ARM.
Step 7 Using a voltage/ohm meter (VOM), make sure continuity exists between pins 16 and 17 and between
pins 35 and 36 at the DB-37 connector on the ARI card.
Step 8 Reconnect the cable that was disconnected in Step 5.
Step 9 With the VOM, check that the reading between pins 16 and 17 and pins 35 and 36 are open and the
MAJOR LED is not on.
Alarm output connections are made at the DB37 connector on the ARI card. The connector pin
assignments with the alarm signal names are listed in Table 3-2. (See the External Alarm Cabling
section on page A-50.)
