Replacing A Cooling Fan Module - Infortrend EonStor U16U-G4010 Installation And Hardware Reference Manual

EonStor U16U Installation and Hardware Reference Manual
♦
Two Redundant Cooling FAN modules - The ES subsystem is equipped with two
redundant, hot-swappable, dual-blower cooling FAN modules located above the PSU
modules. These cooling FAN modules are responsible for controlling the internal
operational temperature of the subsystem and therefore their working integrity
should be maintained at all times.
♦
Detecting a failed cooling FAN Module - If a cooling FAN module fails either the
LED located at the back of the module, an audible alarm, firmware, the RAIDWatch
Panel View, or the NPC can be used to notify a user.
♦
Replacing a cooling FAN module - If a user becomes aware that a cooling FAN
module has failed, it should be replaced as soon as possible. A failed cooling FAN
module should only be removed from the subsystem when the user has an
immediately available replacement module that can be installed as soon as the failed
cooling FAN module has been removed.
WARNING:
Although the cooling FAN modules are fully redundant, it is not advisable to run the
EonStor subsystem with a single cooling FAN module for a long period of time. If the
second cooling FAN module fails the system is at risk of sustaining irreparable
damage.

5.5.2 Replacing a Cooling FAN Module

To replace a cooling FAN module, please follow these instructions:
1. Two retention screws are used to secure the cooling FAN module to the EonStor
subsystem. The first retention screw can be found at the top, on the right, and the
second at the bottom on the left. Remove these retention screws.
2. Once BOTH retention screws have been removed, gently pull the cooling fan
module out of the EonStor subsystem enclosure. (See Figure 5-7).
