Description

RSVD (Port)

The reserved (RSVD) diagnostic port is not required for normal activation or operation. This port supports modem debug or provisioning. See the “Modem Troubleshooting Using the Diagnostic Port” section in Configuring Cisco 4G LTE Wireless WAN EHWIC for details.

Antenna Connectors (Connector)

M1/DIV—Diversity antenna connector, female TNC⁶.

M0/MAIN—Main antenna connector, female TNC.

GPS—GPS antenna connector, female SMA⁷.

See the “Supported Cisco Antennas and Cables” section for details.

WWAN (LED)

Indicates the EHWIC modem status.

Solid green —Indicates the modem is receiving power and is associated and authenticated but not receiving or transmitting data.

Fast green blink —Indicates the modem is receiving power and is associated and authenticated. The blink rate is proportional to the transmitted and received data rate.

Slow green blink —Indicates the modem is receiving power but is not associated or authenticated and is searching for service. Check the antenna, cable, SIM card, or the user account with your service provider.

Off —Indicates the modem is in reset mode.

RSSI (LED)

Indicates the level of signal strength received by the EHWIC software.

Solid green —Indicates a high RSSI (greater than –69 dBm).

Medium green blink —Indicates a medium-level RSSI (from –89 dBm to –69 dBm).

Slow green blink —Indicates a low-level RSSI (from –99 dBm to –89 dBm).

Off —Indicates the RSSI is less than –99 dBm. Check for proper antenna attachment. Adjust antenna placement and orientation.

Solid amber —Indicates no service is detected. Relocate the equipment.

HSPA+ (LED)

Indicates HSPA+ is in service.

Solid green —Indicates HSPA+ is in service.

Off —Indicates that a non-HSPA+ is in service or that there is no service.

LTE (LED)

Indicates whether LTE is in service.

Solid green —Indicates LTE is in service.

Off —Indicates LTE service is not being used.

GPS (LED)

Indicates whether the GPS is in service.

Solid green —Indicates the GPS is active.

Off —Indicates the GPS is not active or not detected.
