Chassis/slot restrictions
•
Not supported in the Catalyst 6503 chassis or the
Catalyst 6509-NEB chassis
•
Supported only in slots 9–13 in the Catalyst 6513 chassis and does
not power up in slots 1–8.
•
When the WS-X6716-10G module is installed in a Catalyst 6500-E
series chassis or a Catalyst 6509-NEB-A chassis, the configuration
is NEBS 3 compliant (chassis supports operating temperatures up
to 55°C).
•
When the WS-X6716-10G module is installed in a Catalyst 6500
non-E series chassis that is equipped with a fan tray 2 and a
2500 W or larger power supply, the configuration is not NEBS 3
compliant (chassis supports operating temperatures up to 40°C
only).
•
Support in the Catalyst 6509-NEB-A chassis requires two
FAN-MOD-09 fan trays be installed.
