Cleaning The Fiber Optic Connectors - HP ProCurve 9304M Installation And Configuration Manual

Figure 5.2 Front panel of 2-port 10 Gigabit Ethernet module
The 10 Gigabit Ethernet interfaces operate at full duplex. The module uses GBIC-like XENPAK Multisource
Agreement (MSA) optics. The XENPAK optics are hot-swappable, allowing you to change the optics without
removing the module from the chassis.
The following kinds of XENPAK optics are supported:
• 1310nm serial for single-mode fiber
• 1510nm serial for single-mode fiber
For the XENPAK optic types listed above, use the matching fiber type with an SC connector. For example, if you
are using the 1310nm serial module for single-mode fiber, attach a 1310nm single-mode fiber cable that has an
SC connector.
System Requirements
The XENPAK-based J8174A 2-port 10 Gigabit Ethernet module is supported in the HP 9304M, HP 9308M, and
HP 9315M.
Hardware on the XENPAK-Based 10 Gigabit Ethernet Module
Each port on the XENPAK-based 10 Gigabit Ethernet modules has a 10 Gigabit Ethernet MAC controller and
separate transmit and receive controllers. The modules have two kinds of FPGAs. The FPGAs enable you to
easily implement architecture upgrades without changing the hardware. The software includes a CLI command
you can use to upgrade the FPGAs if needed. See "Upgrading an FPGA on a 10 Gigabit Ethernet Module" on
page 5-5.
NOTE: The XENPAK-based 10 Gigabit Ethernet modules can function in the same chassis with the non-
XENPAK-based 1-port 10 Gigabit Ethernet modules.
Features Not Supported on XENPAK-based 10 Gigabit Ethernet Modules
The XENPAK-based 10 Gigabit Ethernet modules support all of the applicable Layer 2 and Layer 3 features in
software release 07.6.04 and earlier. The following features are not supported in the current release:
• Rate limiting
• Jumbo packets, if the module is used in a chassis that contains Standard (non-EP) modules. When you use
the module in a chassis containing EP modules, jumbo packets are 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.
