Incorrect or improper use may seriously damage CryptoServer LAN.
2.7
Batteries
The CryptoServer LAN contains two batteries. These ensure that no security-critical
information is lost or deleted in the CryptoServer when the device is switched off, or if
operation is interrupted due to a power failure. The external battery is located in the battery
compartment of the CryptoServer LAN. The carrier battery is placed on the CryptoServer plug-
in card.
These batteries are not rechargeable.
Using the wrong batteries may cause an explosion! Utimaco IS GmbH accepts no liability for
damage caused by using any other batteries except the ones supplied by Utimaco IS GmbH.
2.7.1
External Battery in the Battery Compartment
The external battery placed in the battery compartment behind the front door of the
CryptoServer LAN is a 3.6 V lithium battery (size A) which is directly connected to the
CryptoServer.
This battery is already in use when the device is supplied.
The external battery provides a guaranteed power supply for the CryptoServer for at least 1½
years if the device is not supplied with power via the power cables.
Check the status of this battery at regular intervals. When the battery reaches a critically low
power level, it must be replaced.
Customers are permitted to change the external battery as described in Chapter 4.2 of this
manual.
2.7.2
Carrier Battery of the CryptoServer
On the CryptoServer plug-in card which is integrated into the CryptoServer LAN there is a 3 V
lithium battery – the carrier battery. It powers the sensor and the erase circuit when
CryptoServer LAN is switched off and the external battery in the battery compartment does
not have enough power to supply the CryptoServer.
