Connecting Pluggable Transceivers To The Sfp+ And Qsfp+ Ports - Enterasys 7100G Series Hardware Installation Manual

Connecting to the Network
automatic-polarity sensing which eliminates the need for a crossover cable, regardless of whether
the connection is to another network device or a workstation.
1. Ensure that the far-end device connected to the other end of the segment is powered ON.
2. Connect the far-end device's twisted pair segment into the appropriate 7100G-Series switch
BASE-T port connector.
3. Verify that a link exists by checking that the port RX (Receive) LED is ON (flashing amber,
blinking green, or solid green).
If the RX LED is OFF and the TX (Transmit) LED is not blinking amber, perform the following
steps until it is on:
a.
b. Verify that the device at the other end of the twisted pair segment is on and properly
c.
If a link is not established, refer to
4. Repeat steps 1–3, until all connections have been made.

Connecting Pluggable Transceivers to the SFP+ and QSFP+ Ports

This section describes how to install an SFP+ and QSFP+ pluggable transceiver in appropriate
7100G-Series switch ports. See
pluggable transceiver port locations for your 7100G-Series switch.
For a list of supported SFP+ and QSFP+ pluggable transceivers and their specifications, refer to the
7100-Series firmware Release Notes for the latest compatibility matrix for pluggable transceivers.

2-16 Installation
Note: All RJ45 front panel ports on the 71G21K2L2-48P and 71G21K2L2-24P24 support Category
5E or better cabling.
Verify that cabling is Category 5E or better.
connected to the segment.
Verify that the BASE-T connectors on the twisted pair segment have the proper pinouts
and check the cable for continuity.

Note: A 40Gb QSFP+ port can be configured as four 10Gb SFP+ ports. The 10Gb, QSFP+ to SFP+
adaptor cables (model numbers: 10GB-4-C03-QSFP, 10GB-4-F10-QSFP, or 10GB-4-F20-QSFP)
provide for the single QSFP+ to four SFP+ cable conversion. See the set port speed command
information Enterasys 7100-Series CLI Reference for port configuration details. The two 10Gb ports
are taken off-line when 40Gb ports are used in 4x10Gb mode.
Note: The 10GB-LRM-SFPP SFP+ transceiver cannot be used in QSFP+ ports when using the
Enterasys QSFP+ to SFP+ adapter (Model number QSFP-SFPP-ADPT) to support 10 Gigabit
Ethernet SFP+ transceivers in QSFP+ ports. The 10GB-LRM-SFPP SFP+ transceiver is only
supported on the 7100 in native SFP+ ports.
