7 Is there enough bandwidth to add the new bootloader carousels? (Bootloader
carousels require data rates between 1.00 and 3.00 Mbps.)
If yes, go to Verify a VCI for Inband BFS Sources on BFS BIG Systems (on
page 58).
If no, refer to Recommendations for Data Carousel Rate Management Technical
Bulletin (part number 716377) for details on how to increase the bandwidth of
your system.
Verify a VCI for Inband BFS Sources on BFS BIG Systems
This section describes how to check the number of BFS sessions on your system to
This section describes how to check the number of BFS sessions on your system to
determine whether any unused VCIs are present for the inband BFS carousel.
Notes:
Notes:
Your network was initially installed and reserved with 20 Virtual Channel
Indicator (VCI) connections (values 256-275) on the ATM switch. The VCIs carry
inband BFS information from the DNCS to the BIG. Because you will create a
new inband source, you must make sure that one VCI is available for each
additional bootloader carousel that you add to the DNCS.
If you need detailed instructions for this procedure, refer to the manual that
came with your ATM switch.
Complete the following steps to determine whether there are enough unused VCIs
available for the additional inband BFS carousels.
1 Using the manual that came with your ATM switch, check the ATM switch to

2 Are there enough VCIs for the new bootloader carousels?
If yes, go to Add a Bootloader Source to the DNCS (on page 59).
If no, add more VCIs to the switch. Then, go to Add a Bootloader Source to
the DNCS (on page 59).
Note: Having unused VCIs does not present any issues to your system;
Note: Having unused VCIs does not present any issues to your system;
therefore, we recommend that you create 5 to 10 extra VCIs.
