Reading the LEDs

There are several LEDs on a Cisco Prime NAM 2300 series appliance. LEDs serve the following purposes:

  • Indicate that basic power is available to the appliance
  • Guide you to a broken adapter card, or to one that has failed its diagnostics
  • Give an indication that traffic is flowing through the adapter card to the appliance

The LEDs on the front panel of the Cisco Prime NAM 2300 series appliance and corresponding adapter card are aids for determining appliance and adapter performance and operation.

This section describes the location and meaning of LEDs and buttons and includes the following topics:

Cisco Prime NAM 2304 LEDs

Replacing Transceiver Modules

To replace an SFP or an SFP+ transceiver module in a Cisco Prime NAM 2300 series appliance:

Step 1 Locate the new transceiver module you plan to install, remove any protective packaging, and examine it for any signs of damage.

Step 2 Determine which module you want to replace on the Cisco Prime NAM rear panel.

Step 3 Remove the fiber optical cable from the module to be replaced.

Step 4 With your finger, pull the latch down to release the module from its latched position (see Figure 2-2).

Step 5 Using the latch, pull the SFP+ out of the appliance and place it in a safe location.

Step 6 Insert the new SFP+ into the slot and slide it in until you feel resistance, then push the SFP+ harder until you feel (or hear) it click into its socket.

Step 7 With your finger, pull the latch upwards to lock the SFP+ into its slot (see Figure 2-3).

Step 8 Replace the fiber optical cable.

Removing or Replacing the Cisco Prime NAM 2300 Series Appliances

Always use the NAM CLI command shutdown to shut down the NAM application when you turn power off.

Warning Power off the unit before you begin. Statement 237

Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040

To remove a Cisco Prime NAM 2300 series appliance from your network, power it down, disconnect the power cords and network cables, and physically remove the appliance from the rack.

The appliance is in constant communication on your network, which means that when the network notices that the appliance is no longer responding to it, the network stops sending requests to the appliance. This change is transparent to users. If other appliances are attached to the network, the network continues sending requests to the other appliances.

To replace an appliance, remove it from the network. Then, install a new appliance and configure it using the same configuration parameters that you used for the removed appliance.
