Chapter 3: Pre-Installation Procedures
CPC4400 Ethernet Switch
The CPC4400 is used for the base station’s Ethernet switches. It may be necessary to modify the
jumpers, as the base station uses a configuration of the Ethernet switches that differs from the
manufacturer’s original settings.
NOTE: If the Ethernet switches are pre-installed in the shelves, then they have
already been configured and this procedure is not required.
Table 3.4 shows the correct settings of the Ethernet switch jumpers.
 To configure the Ethernet switches
1 Remove the two Ethernet switches from their antistatic packaging at a grounded work area. Ensure that
you are properly grounded with a wrist or boot strap before handling the cards.
2 Ensure that jumpers K1 to K7 are configured as shown in Table 3.4. Figure 3.2 shows the location of the
jumpers.
NOTE: For jumpers in the OFF position, hang the jumper off the header pins as
shown in Table 3.4. This ensures that the jumper is still present if future changes to the
cards are required.
Jumper Setting Appearance Description

K2–K4 ON User-defined. These jumpers must be left ON.
