Stackable Chassis for DSL Access Growth
Each chassis is an independent, standalone system. The 8610 and 8600 chassis
are interoperable in a stack. The stackable design provides for six systems to
share management access through a single MCP card (for 8610) or MCC card (for
8600) which, in turn, allows an additional slot for a DSL card in each of up to five
additional systems. In a stacked configuration, the first or base chassis is equipped
with an MCP/MCC card in Slot 1 leaving Slots 2 and 3 available for up to two DSL
cards.
Each additional system will accept up to three DSL cards.
A Hotwire 8610 or 8600 DSLAM chassis can be added or removed from the stack
without disrupting data service to the other items in the stack. However,
management service will be disrupted.
The base system is connected to additional systems by connecting the 8-pin
modular expansion cable provided from the OUT port of the base chassis to the IN
port of the next chassis in the stack.

Hot Swappable Cards
The MCP and DSL cards can be installed and removed from the Hotwire 8610
DSLAM chassis without service disruption. You can replace a card without
powering down the chassis and disrupting service to the other cards.
H
Primary Network Management Support via SNMP
SNMP management of the DSL cards is accomplished over a single Ethernet
connection to the MCP card from a Network Management System (NMS) (such as
Paradyne’s DCE Manager for HP OpenView). The MCP card gathers all
management information for each of the DSL cards and responds to the SNMP
requests on behalf of the cards.
For a list of specific management information bases (MIBs) supported, see the
appropriate Hotwire DSLAM Network Configuration Guide.
