Use the subtending mode to daisy-chain other Ethernet switches. With subtending mode, the
management switch card allows traffic between the ports in subtending mode and the ports in
uplink mode. The management switch card does not allow traffic between the ports in
subtending mode and the DSL ports on the line cards.
See Section 34.12.7 on page 897
2.3.2.2 XFP Slots (MSC1224G only) and SFP Slots
These are slots for XFP transceivers and SFP transceivers. A transceiver is a single unit that
houses a transmitter and a receiver. The switch does not come with transceivers.
You must use XFP transceivers that comply with the XFP Multi Source Agreement Group.
See the SFF committee's INF-8077i specification for details.
• Type: XFP connection interface
• Connection speed: 10 Gigabit per second (Gbps)
You must use SFP transceivers that comply with the SFP Transceiver MultiSource Agreement
(MSA). See the SFF committee's INF-8074i specification Rev 1.0 for details.
• Type: SFP connection interface
• Connection speed: 1 Gigabit per second (Gbps)
You can change transceivers while the MSC is operating. You can use different transceivers to
connect to Ethernet switches with different types of fiber-optic connectors.
To avoid possible eye injury, do not look into an operating fiber-optic module's
connectors.
2.3.2.3 Transceiver Installation
Use the following steps to install a mini GBIC transceiver (SFP module) in a slot.
The slot is at an angle. Do not attempt to straighten it.
1 Remove the dust cover from the transceiver.
2 For transceivers with a flip-up or flip-down latch, close the latch.
3 Insert the fiber-optic cables into the transceiver (you may need to remove cable dust
covers).
4 Insert the transceiver into the slot with the exposed section of PCB board facing down.
5 Press the transceiver firmly until it clicks into place.
