Cisco Connected Grid 3G Module Installation and Configuration Guide
OL-25991-01
Hardware Overview
Note Power cables are self-shielded—there is no additional shielding required.
The 2G/3G Connected Grid module has 12V power rail and 3.3V stan-by power provided by the host
system. It has two 3.3V DC-DC converters on the 12V power rail: one for the module and the other for
the modem.
Modem
GSM
The MC8705 PCI Express mini-card modem provides EDGE, GPRS, GSM, WCDMA, HSDPA, HSUPA,
and HSPA+ wireless radio connectivity technologies over the following frequency bands:
MC8705 includes a RF connector jack for use with host antennas (it does not have integrated antennas)
which is used for the main Rx/Tx path.
The MC8705 modem supports the following GSM features:
• Cellular packet data profile
• Traditional modem COM port support for CSD and AT commands (concurrent with NDIS)
• Suspend/resume
• SIM application tool kit with proactive SIM commands
• Static and Dynamic IP address. The network may assign fixed IP address or dynamically assign one
using DHCP (Dynamic Host Configuration Protocol).
