Connecting a network device to a fiber port on the device
For direct attachment from the device to a Gigabit NIC, switch, or router, fiber
cabling with an LC connector is required.
Note: All physical IP interfaces on the Layer 3 devices share the same MAC
address. For this reason, if more than one connection is made between two
devices, one of which is an s-series Layer 3 device, IBM recommends the
use of virtual interfaces. It is not recommended to connect two or more
physical IP interfaces between two routers.
To connect a device to another network device using a fiber port, you must do the
following:
1. Install a fiber optic module (SFP transceiver for Gigabit Ethernet ports, or
XFP-MSA transceiver for 10-Gigabit Ethernet ports)
2. Cable the fiber optic module
The following sections provide information about performing these tasks.
Installing a fiber optic module
You must install a fiber optic module in each Gigabit Ethernet and 10-Gigabit
Ethernet fiber port you want to use.
Attention: Before beginning any of these procedures, read the “Safety notices” on
page xiii.
Before installing a fiber optic module, have the following on hand:
v An ESD wrist strap with a plug for connection to the ESD connector on the
chassis.
CAUTION:
for safety reasons, the ESD wrist strap should contain a series 1 meg ohm
resistor.
To install a fiber optic module into a Gigabit Ethernet or 10-Gigabit Ethernet port, do
the following:
1. Put on the ESD wrist strap and ground yourself by inserting the plug into the
ESD connector located in the lower right corner of the chassis front.
2. Remove the module from its protective packaging.
3. If necessary, remove the metal cover from the port on the interface module’s
control panel.
4. Gently insert the fiber-optic module into the port until the module clicks into
place. The fiber-optic modules are keyed to prevent incorrect insertion.
Cabling a fiber optic module
To cable a fiber-optic module, do the following:
1. Remove the protective covering from the fiber optic module and store the
covering for future use.
2. Before cabling a fiber optic module, IBM strongly recommends cleaning the
cable connectors and the port connectors. For more information, see “Cleaning
fiber optic modules” on page 53.
