For Symmetra models with 4, 3, or 2 slots, install each card, starting with the lowest priority (as listed in the table on page 18) in the lowest numbered slot. Use the following illustrations to determine model-specific slot numbering.
•When 4 slots are available, arranged in a horizontal row, the lowest-numbered slot is at the right.
•When slots are arranged in a vertical column:
–If 3 slots are available, the lowest-numbered slot is at the top (as shown in the following illustration).
–If 2 slots are available, the lowest-numbered slot is at the bottom (as shown in the following illustration).
When a management card has been pre-installed.For Symmetra UPS models that are shipped with a Network Management Card already installed (such as Symmetra RM models), the UPS itself may have only one remaining card slot available. Referring to the table on page 1, install the lowest priority card in the UPS and use one or more expansion chassis for any other cards, as described beginning on page 2. To use an Out-of-Band Management Card, install it in the highest-numbered slot of the expansion chassis farthest from the UPS.
