SmartEdge 600 Router Hardware Guide
two routers. This card is based on the third generation of the PPAs and has
increased port density compared with previous 10GE cards. It supports up
to 48K circuits per card. This 4-port 10GE card is capable of a maximum
throughput of 20 Gbps. It can be used in ingress oversubscription mode at a
maximum of 2 to 1 (40 Gbps over four 10GE faceplate ports; 20 Gbps within the
card and across the backplane). Ports on this card can be configured in one of
two ingress oversubscription modes for incoming traffic: priority-based packet
discard for traffic from trusted networks and random-based packet discard
from unfiltered nontrusted networks.
To allow for optimal operation in cases of ingress oversubscription, generation
of Ethernet PAUSE frames for receive flow control purposes is automatically
disabled for all ports on a 4-port 10GE card whenever three or more ports on
the same card are placed in operation using the
no shutdown
command.

This card is the same size as all other SmartEdge line cards and occupies a
single slot in the chassis. The following types of 10-Gbps XFP transceivers are
supported on any of the ports:
• 10GE-SR—Short Reach
• 10GE-LR—Long Reach
• 10GE-ER—Extended Reach
• 10GE-ZR—Extreme Reach
• 10GE-DWDM—Dense wavelength-division multiplexing
Caution!
Risk of data loss. You can corrupt the system if you attempt to install
transceivers (GBICs, SFPs, or XFPs) that are not purchased from Ericsson
because these items have not been tested with the SmartEdge router. To
reduce the risk, install only the transceivers purchased from Ericsson.
Note: When ordering the XFP transceivers with 10GE ZR functionality, use
part number XFP-OC192-LR2.
