Checking the Installation

For AC-input power supplies, the green AC OK LED should go on. For DC-input power supplies, the

green input OK LED should go on. For both types of power supplies, the output fail LED should be off.

Step 2 Listen for the system blower modules or fan trays in the router; you should immediately hear them

operating. In a noisy environment, place your hand in front of the exhaust vents to verify that the blower

modules are operating.

Step 3 During the PRP boot process, observe the PRP alphanumeric display LEDs, which are located at one end

of the PRP, near the ejector lever. (See Figure 8.)

The 4-digit displays show system messages and displays a sequence similar to that shown in Table 6.
