Powering up a System

When bringing up an FC-AL system, first make all the connections with the

equipment powered down, then turn on the fibre loop switch before turning on

any other operating component. The fibre loop switch does not have an On/Off

switch. For convenience and safety, connect the power cord to a grounded AC

outlet near the rack or desk so it is easily accessible. Ensure that the appropriate

power plug is available for the installation area.

Plug the power cord into the loop switch's power receptacle, then plug

the opposite end into a power receptacle.

On power-up or when you press the reset button, the switch runs several

power-on self tests during start-up. The LEDs display changing patterns.

See Table 1 on page 3 to interpret the LEDs as the switch comes up.

Power on a host and I/O units.

Verify the presence of the I/O from units on the host.

Start the server application.

The fibre loop switch supports connection to multiple media formats.

Note:

•

Cabling requirements for the fibre loop switch depend on the GBICs installed.

Depending on the GBIC, it can support multi-mode fiber, single mode fiber, or

The following rules should be observed regarding cabling:

Support and route the cables to prevent damage from sharp edges or from

being crushed by nearby equipment.

It is important to route copper cables so that they do not introduce noise.

Don't lay them over transformers or alongside power cables for any

distance.

Provide support for installed cables, and do not allow them to have a bend

radius of less than 3 inches (76 mm). This is particularly important with

fiber optic cables as a sharp bend can decrease their performance even if

they are not physically damaged.

When connecting fiber optic cables together with a barrel connector, make

sure that both fibers are the same mode and diameter.

Laser types at each end of a link must match.
