Figure 32: Removing a SFP Module without Bale-Clasp Latch From Cisco ASR 920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Router
SFP module without Bale-Clasp Latch—Use the extraction tool to remove the SFP by inserting the tool into
the side of the SFP module and pulling it out of the module as shown in the figure below.
Step 4
Grasp the SFP module between your thumb and index finger, and carefully remove it from the module slot.
Step 5
For fiber-optic SFP modules, insert a dust plug into the optical ports of the SFP module to keep the optical
interfaces clean.
Step 6
Place the removed SFP module in an antistatic bag or other protective environment.
Connecting to the 10/100/1000 Ports
The router 10/100/1000 ports configure themselves to operate at the speed of attached devices. If the attached
ports do not support autonegotiation, you can explicitly set the speed and duplex parameters. Connecting
devices that do not autonegotiate or that have their speed and duplex parameters manually set can reduce
performance or result in no linkage.
Note
To maximize performance, choose one of these methods for configuring the Ethernet ports:
• Let the ports autonegotiate both speed and duplex.
• Set the port speed and duplex parameters on both ends of the connection.
Procedure
Step 1
When connecting to workstations, servers, and routers, connect a straight-through cable to an RJ-45 connector
on the front panel.When connecting to routers or repeaters, use a crossover cable.
You can use the
mdix auto
interface configuration command in the CLI to enable the automatic
medium-dependent interface crossover (auto-MDIX) feature. When the auto-MDIX feature is
enabled, the router detects the required cable type for copper Ethernet connections and configures
the interfaces accordingly. Therefore, you can use either a crossover or a straight-through cable for
connections to a copper 10/100/1000, or an SFP module port on the router, regardless of the type
of device on the other end of the connection.
