3.11 SIM Auto Manage
Use the SIM Auto Manage screen to configure the Gateway to automatically
alternate and/or discontinue use of SIM cards. This enables load-balancing between
a GSM module’s SIM cards based on preconfigured switched time cycle.
To enable automatic management of SIM cards:
1. From the Cellular Cards branch of the HMC navigation pane, click the SIM
Auto Manage sub-branch. The SIM Auto Manage screen is displayed.
Figure 40. HMC SIM Auto Manage Screen
2. If more than one slot is displayed, select a specific Cellular Card. The SIM Auto
Manage screen of that cellular card is displayed.
3. Select the checkbox beside a module number in the Enable Auto Switch column.
The SIM column checkboxes and Minutes column fields are displayed.
4. To assign a SIM card to a module, select the checkboxes in the SIM column.
Note:
In Figure 40, each module has two SIM cards assigned to it. The Gateway will allow
a SIM card to function for 1000 minutes and then switch to the second SIM card. Once a
SIM card has functioned for 4000 minutes
—that is, 4 cycles—it is blocked. It can only be
unblocked manually.
5. In the Minutes until SIM is switched field, enter an amount of time measured
in minutes. This is the how long each SIM card will be used until the Gateway
automatically switches to the next SIM card assigned to that module.
6. In the Minutes until SIM is blocked field , enter an amount of time measured in
minutes. This is the total amount of time a SIM card is used before the Gateway
discontinues using it.
7. Click Apply Settings and wait for Configuration Saved to be displayed.
