Cisco Connected Grid 3G Module Installation and Configuration Guide
OL-25991-01
Installing and Removing the SIM Card (GSM Module)
The module begins a shutdown sequence and powers off if it has been in a powered-on state for more
than 10.5 seconds and the host device drives the W_Disable# signal low for:
MC8775/MC8775V: >= 50 ms
Other devices: >= 500 ms
Installing and Removing the SIM Card (GSM Module)
Two GSM (Global System for Mobile Communications) SIM card sockets for storing critical subscriber
authentication information. The SIM card can be installed in either of the two available sockets
accessible on the front panel of the Cisco Connected Grid 3G Module.
Note You must reload the system after installing or changing the SIM card.
Preventing Electrostatic Discharge Damage
Electrostatic Discharge (ESD) damage can occur when electronic cards or components are handled
improperly, and can result in complete or intermittent failures.
To prevent ESD damage:
Always use an ESD wrist or ankle strap and ensure that it makes good skin contact
Connect the equipment end of the strap to an unfinished chassis surface
Place a removed compact SIM card on an antistatic surface or in a static shielding bag. If the card
will be returned to the factory, immediately place it in a static shielding bag
Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages
on the body only; ESD voltages on clothing can still cause damage
Do not remove the wrist strap until the installation is complete
Warning
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Statement 1030
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be
between 1 and 10 megohms (Mohms).
Installing the SIM Card (GSM Module)
To install the SIM card:
Step 1 Using a Phillips-head screwdriver, loosen the screw that secures the SIM slot cover in place. Rotate the
cover downward so it exposes the SIM slot.
Step 2 Insert the SIM card with the key (notch) positioned on the right-hand side. The SIM card will come in
contact with the metal contacts in the socket.
