[IDL-2402] Does the IDL-2402 support “Hardware Stackable” feature?

No, the IDL-2402 doesn’t support “Hardware Stackable” feature, but it supports “Cluster” feature or called IP Stacking. This “Cluster” function allows you to make a group of IDL-2402 work together as a single NE (Network Element) for management by one management IP.
Currently an IDL-2402 cluster can support up to four (4) IDL-2402. The IP DSLAM in a cluster must all be in-band connected through the Uplink port. It uses star topology for conducting a Clustering Management Group.
