Caution
7
When using an HXGS3 board in the upper slot row in HiPath 3550 (slots 4, 6, 8) or
HiPath 3350 (slot 4), fan kit C39165-A7021-D3 must be installed for thermal rea-
sons!
The fan kit is not necessary when using an HXGS3 board in the lower slot row (slots
5, 7, 9 in HiPath 3550 and slot 5 in HiPath 3350).
Installing the fan kit marks the end of silent system operation. This must be taken
>
into consideration when operating the system in an office environment.
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 3-51.
4. Push the two supplied securing clips over positions [C] illustrated in Figure 3-52
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 3-53.
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.
