EXTENSION CUTDOWN
3.7.1
Extension Cutdown Sheet Configuration
Due to the inherent flexibility of the universal blade slot configuration, standard cutdown sheets for extension
cabling do not apply.
For example, given that a 16ESIU is installed in slot #2 and uses extension numbers 301-316, if three 16ESIU
blades or 8SLIU with the 8SLIDB blades were installed in the system in the order below, the numbering plan
would correspond as follows:
To determine extension assignments for the system cutdown, the installer must identify the following in order:
●
Order of installation
●
Chassis (Controlling/Base, Expansion)
●
Slot used
●
Blade type (8ESIU, 16ESIU, 4SLIU, 8SLIU, 8SLIDB, etc.)
●
Connector used on blade
To determine where any group of eight extensions is installed, note the order of install, chassis, slot, blade
connector and blade type.
Order of Install Blade Slot # Ext Numbers
1 1 301-316
2 2 317-332
3 4 333-348
4 3 349-364
The order in which the extension blades (8/16ESIU, 4/8SLIU, 4/8SLIDB) are
installed determines the assigned extension number.
