August 5, 1999



Products Affected

Problem Description

Cisco Manufacturing has identified that it shipped out CISCO1601-R routers with the front panel LED installed incorrectly. The LED polarity was reversed, as a result the LEDs will not illuminate.

Problem Symptoms

The front panel LEDs will not light up, but otherwise the router functions perfectly. As long as the LEDs are not required by the customer, the defective routers are suitable for long term deployment.

Serial Numbers: JAB0324XXXX through JAB0329XXXX and JAC0324XXXX through JAC0329XXXX.

Workaround/Solution

  1. Units that have not been opened may be returned at the customers discretion.
