Руководство По Установке для Cisco Cisco DWDM Transceiver Modules

You will need these tools to install the XENPAK transceiver module:

Small flat-blade screwdriver to loosen or tighten the XENPAK transceiver captive installation 
screws.

Wrist strap or other personal grounding device to prevent (Min) dischage (ESD) occurrences.

Antistatic mat or antistatic foam to set the XENPAK transceiver on.

Fiber-optic end-face cleaning tools and inspection equipment. For complete information on 
inspecting and cleaning fiber-optic connections, refer to the white paper at this URL:

The 10-Gigabit XENPAK transceiver is a static-sensitive device. Always use an ESD wrist strap or 
similar individual grounding device when handling the XENPAK transceivers or coming into contact 
with the modules.

To install a 10-Gigabit XENPAK transceiver, follow these steps:

Remove the 10-Gigabit Ethernet XENPAK transceiver from its protective packaging.

Do not remove the optical bore dust plugs until directed to do so later in the procedure.

Check the label on the 10-Gigabit Ethernet XENPAK transceiver body to verify that you have the correct 
model for your network. Refer to 

to verify that the product number matches the desired band and 

channel. 

Align the XENPAK transceiver with the opening in the module faceplate, and slide the XENPAK 
transceiver into the opening until the XENPAK transceiver faceplate is in contact with the module 
faceplate. (See 

.) This step ensures that the XENPAK transceiver is fully seated in the module 

socket.

Tighten the two captive installation screws to secure the XENPAK transceiver in the socket. Avoid 
cross-threading or overtightening the captive screws.

Any optical signal greater than -1 dB can damage the DWDM XENPAK transceiver. The maximum 
sensitivity for the DWDM XENPAK receiver is -7 dB. You must use a 10 dB attenuator on short 
fiber-optic cable runs to prevent damage to the DWDM XENPAK transceiver and to guarantee the 
specified performance.
