Equipment Reliability
Protection Scheme
Description
Suggestion
Main control board 1
+1 protection
The system uses two main control
boards of the same model and
version. The two main control boards
work in the active/standby mode by
default. When the active main control
board fails, the system switches to the
standby main control board to
prevent service interruption.
Mandatory
Power board 1+1
protection
A subrack is configured with two
power boards of the same model and
version, which back up each other.
When one of the power board fails,
the other power board can still
provide power supply to the device
and so the system can still work
properly.
Mandatory
Upstream board 1+1
protection
The system uses two upstream
interface boards of the same model
and version. Each GIU board
provides one upstream port and two
upstream ports are bound together
using Link Aggregation Control
Protocol (LACP). When the active
upstream port fails, traffic will be
transmitted upstream through the
standby upstream port.
This protection scheme is
recommended when the
GIU board is used to
transmit traffic upstream.
Upstream Networking Protection
Protection Scheme
Description
Suggestion
Link aggregation
group
Multiple Ethernet ports are bound
together as an aggregation group to
increase the bandwidth and balance
the inbound and outbound load of
each member port. In addition, the
ports in an aggregation group back up
each other, which enhances the
reliability of links.
This protection scheme is
mandatory when the GIU
board is used to transmit
traffic upstream.
