corresponding secondary ports on the EP6. If Ethernet port availability in the
data center is an issue, connect to the primary Ethernet ports on the EP6 first.
– R1350 installed in an R4200 chassis—Only the primary port on the R1350
is connected.
Single-Slot Blades
Single-processor blades previous to the R1300 contain one Ethernet adapter. The
R1300 provides two Ethernet adapters. Therefore, connecting a network cable to
each of the blade's Ethernet jacks on the chassis will provide the user with two
independent network connections and greater bandwidth.
The dual Ethernet ports on the R1300 are accessible as follows:
• For a 16-port EP6 module in an R4300 chassis, all ports are available. The primary
ports on the blade are connected to the corresponding primary ports on the EP6,
and the secondary ports on the blade are connected to the corresponding
secondary ports on the EP6. When Ethernet port availability in the data center is an
issue, always connect to the primary Ethernet ports on the EP6 first.
• In an R4200 chassis, only the primary ports on the R1300 are connected.
The single Ethernet port on the R1200 and previous blades is accessible as follows:
• For a 16-port EP6 module in an R4300 chassis, the Ethernet port on the blade is
connected to the corresponding primary port on the EP6. The secondary port on
the EP6 is not used.
Double-Slot Blades
Dual-processor blades contain two Ethernet adapters – one for each chassis slot.
Therefore, connecting a network cable to each of the blade's Ethernet jacks on the
chassis will provide the user with two independent network connections and double
the bandwidth.
To connect C/Ports to a double-slot blade, use only the even-numbered C/Port
connectors 2, 4, 6, or 8, relative to those slot pairs. The odd-numbered C/Port
connections on the chassis are not connected to double-slot blades.
The dual Ethernet ports on double-slot blades are accessible as follows:
• For a 16-port EP6 module in an R4300 chassis, a double-slot blade in slots 1&2,
3&4, 5&6, or 7&8 uses primary Ethernet ports 1&2, 3&4, 5&6, or 7&8,
respectively. Secondary ports on an EP6 are not connected to a double-slot
blade.
Using USB 2.0 Capability on the R1300 and R2200
The R1300 and R2200 provide two USB 2.0 ports, one on the front of the Blade and
one on the back apron of the R4300 when the blade has a 44-pin interposer installed.
The 30-pin interposer does not bring the USB 2.0 signals onto the R4300 signal
backplane.
The USB port on the R1300 connects to the corresponding USB port on the R4300.
When connecting to an R2200, use the even-numbered USB ports on the back apron
of the R4300. The odd-numbered USB ports on the chassis are not connected to the
R2200. This is the same scheme as with connecting C/Ports to a double-slot blade,
