Determining Power Supply - HP ProCurve 9304M Installation And Configuration Manual

2. Disconnect the two fiber cable connectors from the port connectors.
3. Insert the protective covering into the port connectors.
4. Using the flathead screwdriver if necessary, loosen the two thumbscrews on the ends of the XENPAK optic.
5. Pull the XENPAK optic out of the port, and place it in an anti-static bag for storage if desired.
6. Install a new XENPAK optic in the module, if necessary. For information about performing this task, see
"Installing a XENPAK Optic" below.
Installing a XENPAK Optic
To install a XENPAK optic in a 10 Gigabit Ethernet module, do the following:
1. Put on the ESD wrist strap and attach the copper tape to a metal surface (such as an equipment rack) to act
as ground.
2. Remove the new XENPAK optic from its protective packaging.
3. Gently insert the the XENPAK optic into the module until it clicks into place. The XENPAK optics are keyed to
prevent incorrect insertion.
Secure the XENPAK optic by tightening the two thumb-screws. If desired, you can further tighten the thumb­
screws using the flathead screwdriver.
Software Support for XENPAK Optics
Hewlett-Packard offers and supports only XENPAK optics that include an HP label (product number J8173A,
1
J8175A , or J8176A) for use with the J8174A HP ProCurve 9300 XENPAK module. Use of other brands of optics
or the use of HP-labeled XENPAK optics in non-HP device is not supported.
Cleaning the Fiber Optic Connectors
To avoid problems with the connection between the fiber-optic module connectors and the fiber cable connectors,
HP strongly recommends cleaning both connectors 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.
To clean the fiber cable connectors, HP recommends using a fiber-optic reel-type cleaner. You can purchase this
type of cleaner from the following Web site:
http://www.fisfiber.com/fisfiber.com/Home_Page.asp
To clean the fiber-optic module connectors, HP recommends using a product that dispenses dust-free air, such as
Micro-Blast. You can purchase such a product from the following Web site:
http://www.microcare.com/product/solvents/PS-50.html.
When cleaning a fiber-optic module connector, do not use unfiltered air from an air compressor, cotton swabs, or
other types of swab applicators. These types of products may leave lint or dust in the connector.
Also, when not using a fiber-optic module connector, make sure to keep the protective covering on.
