4k VLAN Support at the Controller
In order to Address Service Providers scalability requirements, the 7.3 software release extends the number
of supported VLANs to 4096.
This enables location−based service per Interface/VLAN as the number of maximum interfaces has also been
increased from 512 to 4096 (4095 + management interface) and associated VLANs.
Note: The 4k VLAN is supported only on the 8500 and Flex7500 Controllers.
Dual−redundant DC Power
In order to accommodate Service Provider DC power requirements, the 8500 can be ordered in a
Dual−redundant −48V DC power supply configuration.
Input voltage range: Minimum: −40VDC and Maximum: −75VDC
Note: The DC powered 8510 controller does not ship with any of the country specific power cords. For the
DC powered units, you should use your own 12G wire and connect to the DC power supply.
