7.1 General Maintenance
Periodically perform maintenance on your OptiStar EdgeSwitch. Keep components free of dust and other
particulate matter. Check fans for reduced airflow caused by dust build-up and clean as necessary. Examine
cables and fiber for damage and ensure that airflow requirements have been met. Otherwise, no special
maintenance is required.
7.2 Hardware Replacement
7.2.1 Network Module Replacement
A Network Module may need to be replaced for one of two reasons; the Network Module needs to be upgraded
or the Network Module is faulty. Indications of a faulty Network Module include:
•
The LED on the Network Module goes out indicating that traffic is not running through the ports on the
module.
•
On the FCIP Network Module only, the operational status of the Module is
DOWN
(see Section
5.1.2.4 entitled “Switching Module Parameters” ).
•
The Power On Self Test (POST) fails upon reboot.
•
The Network Module does not properly boot up when the OptiStar EdgeSwitch is rebooted.
The following tutorial explains how to replace a Network Module on the OptiStar EdgeSwitch.
Note
: Before replacing any of the Network Modules, make sure you are grounded with a wrist strap. For
information on grounding, see Section 3.4.2 entitled “Installing the Network Modules” .
To remove a Network Module from the OptiStar EdgeSwitch, please use the following steps:
Step 1
Disable the module using the software commands in Section 5.4.2, “Set Module Admin Status” . Even
if the Network Module is faulty, the module should be administratively disabled so that there is no
power to the slot when the replacement module is inserted.
WARNING
: If slot is “hot” when the new
board connects with the back plane, then the module will immediately power up, which will result in
an abnormal and potentially faulty boot process. In addition, there is a slight chance that inserting the
new module in to a “hot” slot may damage the module or pose a safety threat to the person inserting
the module.
Step 2
Carefully disconnect the cables from the module you want to remove and loosen the thumbscrews.
Step 3
Gently grasp the release levers on the front edges of the module and pull towards you, taking care to
pull straight out of the guide frame (see Figure 7-1). Handle Network Modules only by the edges;
avoid touching the board or excessively handling the connector cable.
