Replacing data cards and processing hardware
Besides the hard disk, power supply, and cooling fans, a number of components the BCM1000
uses for data functions can be replaced.
These components can be replaced:
• WAN cards
• LAN cards
• modem cards
• computer memory
• PEC cards
• motherboard battery
Replacing data cards
Depending on your location, you can have various configurations of data cards that can include
WAN card, LAN, and modem cards (North America, only). All three types of cards are removed
and replaced in the same manner, the only difference being which PCI slot they are inserted into.
For a description of the function of each type of card on the BCM1000, refer to “Data networking
components” on page 75 .
Figure 141 provides a general procedure for card replacement in the PCI slots of the BCM1000.
