Credit Crisis Spreads Cisco Systems

Cisco Systems warned that a sharp drop in sales could push quarterly revenue down by as much as 10 percent.

The computer networking giant, the first major technology company to report earnings that include October, when the credit crisis spread beyond financial companies, said Wednesday that its sales had fallen 9 percent from the same month a year earlier.

Cisco expects sales for its current quarter to drop 5 percent to 10 percent from the $9.8 billion reported in the same period a year ago.
