Removing/Swapping a Power Supply Module
You can remove or swap out a power supply module (AC or DC) while the CryptoServer LAN is
running normally.
Be sure to wear gloves when removing a power supply module to prevent being burned. The
temperature of the failed power supply module might be around 50 ~ 60 °C.
The following example shows step-by-step how to replace the upper AC power supply module
as shown in Figure 18. For replacing a DC power supply module follow the same steps for the
elements shown in Figure 19.
If a power supply module fails, and needs to be replaced, follow these steps:
1.
Switch off the relevant power supply module with the power supply switch a5/d5.
2.
Disconnect the power cable from the relevant power supply module (the upper one in our
example figures).
3.
On a CryptoServer LAN V4 variant c (Figure 2 resp. Figure 6), undo the screw used to
attach the guard bracket a17/d15 by using a screwdriver. If you are using a CryptoServer
LAN V4 variant b (Figure 1 resp. Figure 5), skip this step.
4.
Using a screwdriver, undo the relevant screw a7/d7, which is being used to attach the
power supply module on the CryptoServer LAN.
