• If the server is within reach, and the amber LED is lit on the front operator panel, potential liquid leaks may
have occurred. It is required to open the top cover to check the LED status of the leakage detection
sensor module. See
“Front-operator-panel LEDs and buttons” on page 301 and “LED on the leakage
detection sensor module” on page 303
for more details.
Steps to resolve liquid leaks
If the LED on the leakage detection sensor module is blinking green, follow the procedures to get help.
1. Save and back up data and operations.
2. Power off the server and remove the quick connect plugs from the manifolds.
3. Slide the server out or remove the server from the rack. See “Install the server to the rack (friction rails)”
on page 85
or “Install the server to the rack (slide rails)” on page 93.
4. Remove the top cover. See
“Remove the top cover” on page 282.
5. Check for liquid leaks around the outlet and inlet hoses, system board assembly, and under the cold
plate covers:
Figure 335. Leak-prone areas
Note: If leak happens, the liquid tends to collect around
1 leak-prone areas.
a. If liquid found around the hoses and system board assembly, clean up the liquid.
b. If liquid found under the cold plate covers:
1) As illustrated below, remove at least four DIMMs from both sides to get access to the clips on
the cold plate covers. To remove memory modules, see
“Remove a memory module” on page
210
