The ship's AV and NavCom room air conditioning system failed over a weekend and the affected equipment includes three pieces of Cisco C2960-S Series 10G (x3) and one piece of a Cisco 2901 VK9
Historical temperature monitor data shows
a. Over 110 degrees Fahrenheit for approximately 43 hours
b. Over 120 degrees Fahrenheit for approximately 41 hours
c. Over 130 degrees Fahrenheit for approximately 38 hours
d. Over 140 degrees Fahrenheit for approximately 36 hours
e. Over 150 degrees Fahrenheit for approximately 31 hours
f. Over 160 degrees Fahrenheit for approximately 24 hours
g. Over 165 degrees Fahrenheit for approximately 10 hours
h. The peak temperature in the room was measured to be 168.7 degrees Fahrenheit
Do we need to replace these Cisco switches to ensure reliability at sea?

Cote_Marine,
d. Over 140 degrees Fahrenheit for approximately 36 hours
e. Over 150 degrees Fahrenheit for approximately 31 hours
f. Over 160 degrees Fahrenheit for approximately 24 hours
g. Over 165 degrees Fahrenheit for approximately 10 hours
h. The peak temperature in the room was measured to be 168.7 degrees Fahrenheit
These numbers are pretty high. Knowing you are at sea and the equipment is critical to your mission, I would try to cool off the room with some fans for now, but look at replacing them as a long term solution.

Very good question. The technician did not look into this.
He is also the one who declared the switches to be A-OK after testing for two hours in a low ambient temperature environment. I question the validity of this test.
