See "Interface Specifications for SFP, SFP+, and QSFP+ Transceivers for an ACX5000
Router" on page 62 and "Interface Specifications for SFP+ DAC Cables for an ACX5000
Router" on page 77. All 96 of these ports can be used for SFP+ transceivers or SFP+
direct attach copper (DAC) cables. You can use 1-Gigabit Ethernet SFP+,
10-Gigabit Ethernet SFP+ transceivers and SFP+ direct attach copper cables in any
access port.
CAUTION: Do not place a copper transceiver in an access port directly above
or below another copper transceiver. Internal damage to the access ports
and router can occur. We recommend either using the top port row exclusively,
or bottom port row exclusively, for copper transceivers.
The port panel of an ACX5096 supports up to a maximum of 104 logical 10 GbE ports
that can be distributed over 96 small form-factor pluggable plus (SFP+) and 8 quad
small-form factor pluggable plus (QSFP+) transceivers . Because of an 104 port restriction,
only two of the eight QSFP+ can be channelized. Depending on how you set the system
mode for channelization, the behavior of channelization for the QSFP+ changes. The
following system modes are available for the ACX5096 router:
Non-oversubscribed
All 96 SFP+ ports on the router (PIC 0) are supported. In this mode, the eight QSFP+
ports are not supported and cannot be channelized. There is no packet loss for packets
of any size in this mode.
Default mode
All 96 SFP+ ports on the router (PIC 0) are supported. QSFP+ ports
be channelized. If ports 96
