5.4.2 New Installation

On new installations, make sure that all steps in Chapter 2 are complete, then follow these steps:

1. Check that the STA LED is green.

2. Check that the fiber type (multimode or single mode) matches the 9155 optical mode.

3. Make these checks:

• All fiber cabling is of the same type; do not mix multimode and single mode cables.

• The fiber optic cable is within the specifications and loss budget of the optic interface

module.

• The line length between the 9155 and the remote link does not exceed the allowable loss

budget or overdrive limit.

• All host modules in the link are turned on.

• All fiber cables are connected Tx to Rx and Rx to Tx.

If a link is down, inspect and clean the cables and connectors, then replace any damaged fiber. Retest

modules after cleaning.
