Installing the fan kit for HXGS3 in HiPath 3550 or HiPath 3350
Caution
7
When an HXGS3 board is used in a HiPath 3550 or HiPath 3350, one fan kit
C39165-A7021-D3 must be installed for thermal reasons.
When installing and connecting the fan kit, proceed as follows:
Step
1. Disconnect system from power supply.
Caution
System voltage can only be switched off by taking out the power plug. Switch off
the battery voltage first for an uninterruptible power supply.
2. Open the system.
Warning
Grasp the housing cover by its outside walls only.
The shielding plate on the inside of the cover may have sharp edges which can
cause cuts (see Section 4.4.3.4, "Removing the System Housing Cover").
3. Place fan kit [A] on the system shelf [B] as shown in Figure 3-47.
4. Push the two supplied securing clips over positions [C] illustrated in Figure 3-48
to attach the fan kit to the shelf.
5. Insert the connector of the fan kit cable into the port provided for it on an HXGS3
board as illustrated in Figure 3-49.
6. Close the system.
Warning
Grasp the housing cover by its outside walls only.
7. Start the system by plugging in the power plug. In the case of an uninterruptible
power supply, the battery must then be switched on.
