NEW YORK, May 1 (Reuters) - Network equipment maker Cisco Systems Inc's (CSCO.O) quarterly results are likely to show signs of stabilization, but CEO John Chambers is expected to give a cautious outlook after some previous forecasts proved excessively sanguine.

Analysts on average expect Cisco's revenue to be $8.08 billion for its fiscal third quarter ended April 25 when it reports results on May 6, according to Reuters Estimates.

That would represent a 17 percent decline from the year earlier period and lands in the middle of the company's previously announced projection of a revenue decline of 15 percent to 20 percent for the quarter.

The expected results diverge considerably from the company's previous long-term growth target of 12 percent to 17 percent.
