Cabling the Line Cards
Note
Whenever you connect cables to a DS-48 line card, use a wrist-strap or other grounding device to prevent
ESD damage.
Connecting the Gigabit Ethernet Ports
The Gigabit Ethernet ports support IEEE 802.3z specifications for 1000-Mbps transmission over
fiber-optic cables. These ports also support autosensing and autonegotiation of the proper transmission
mode (half duplex or full duplex) with an attached device. Cables connect to the Gigabit Ethernet ports
via small form-factor pluggable (SFP) modules.
A list of compatible Cisco approved SFP modules is listed in

Installing SFP Transceiver Modules in the Line Cards
The SFP transceiver modules have three different types of latching devices to secure an SFP transceiver
in a port socket:
•
•
•
Determine the type of latch your SFP transceiver uses before proceeding.
Caution
We strongly recommend that you do not install or remove the SFP transceiver module with fiber-optic
cables attached to it because of the potential damage to the cables, the cable connector, or the optical
interfaces in the SFP transceiver. Disconnect all cables before removing or installing an SFP transceiver.
Note
Do not remove and insert SFP transceivers more often than is absolutely necessary. Frequent removal
and insertion will reduce the life of the SFP transceiver.
Caution
The SFP transceiver modules are static sensitive devices. Always use an ESD wrist-strap or similar
individual grounding device when handling SFP transceivers.
