1. Remove the protective covering from the fiber-optic port connectors and store
2. Before cabling a fiber optic module, clean the cable connectors and the port
3. Gently insert the cable connector or connectors (a tab on each connector
4. Observe the link and active LEDs to determine if the network connections are
Cleaning the fiber-optic connector: To avoid problems with the connection
between the fiber optic module (SFP (mini-GBIC) or SFP+) and the fiber cable
connectors, clean both connectors thoroughly each time you disconnect and
reconnect them. In particular, dust can accumulate in the connectors and cause
problems such as reducing the optic launch power.
When not using an SFP or SFP+ connector, make sure to keep the protective
covering on.
Testing connectivity
After you install the network cables, you can test network connectivity to other
devices by pinging those devices. You also can observe the LEDs related to
network connection and perform trace routes.
Pinging an IP address
To verify that a device can reach another device through the network, enter a
command such as the following at any level of the CLI on the device.
TurboIron> ping 192.33.4.7
Syntax: ping <ip addr> | <hostname> [source <ip addr>] [count <num>]
[timeout <msec>] [ttl <num>] [size <byte>] [quiet] [numeric] [no-fragment]
[verify] [data <1-to-4 byte hex>] [brief]
Note: If you address the ping to the IP broadcast address, the device lists the first
Observing LEDs
After you install the network cables, you can observe certain LEDs to determine if
the network connections are functioning properly. Table 8 on page 25 describes the
LEDs related to network connections, the desired state of each LED, possible
abnormal states of each LED, and what to do if an LED indicates an abnormal
state.
