Installation Instructions for 4 PORT DS1/E1 CEM-1 Module

 IMPORTANT The following instructions are intended to be carried out by certified technical personnel. 

CAUTION

? To avoid high voltage static discharges which may damage the module’s components, alway s

wear an antistatic wrist strap when inserting or extracting a module. Ensure that the wrist strap

 makes good contact with your skin and that it is properly connected to the chassis' internal

 common ground through the ESD jack near the upper right of the front panel. 

?  Hold the module by its panel edges. Avoid contact between your fingers and the module’s

 connector pins.

?  Modules and other ESD-sensitive components that are not in use should be stored in antistatic

 bags. 

 IMPORTANT 

 For proper ventilation and protection of the equipment against dust, moisture and foreign objects,

 make sure that empty slots are always covered securely by blank faceplates. 

Installation Procedure:

The Alcatel 7250 chassis can accommodate up to two 4 PORT DS1/E1 CEM-1 modules in slots 4 and 

5. To insert a 4 PORT DS1/E1 CEM-1 module, proceed as follows: 

1.  Loosen the screws that secure the blank faceplate to the desired slot and remove the faceplate.

2.  Slide the module carefully all the way into the slot. 

When inserting the module into its slot, gently mate the boards with the chassis backplane using

 moderate pressure. 

3.  Verify that the retention screws are aligned with the threaded holes in the chassis. 

4.  Tighten the retention screws by hand or with a screwdriver. 

To avoid overheating of the Alcatel 7250 components by improper air-flow, always keep empty slots

covered. Use the panel screws on the blank  filler faceplates to fasten them to the appropriate empty

slots.

Firmware Upgrade 

The executable firmware contained on the 4 PORT DS1/E1 CEM-1 module can be upgraded via the

network whenever new versions become available, reflecting changes or enhancements to the

firmware. The firmware is stored in erasable Flash memory. It must be downloaded using the Trivial

File Transfer Protocol (TFTP).

 Preparing to Download an Image Using TFTP

Before you begin to download firmware using TFTP, take the following precautions: 

Ensure that the workstation acting as TFTP server is configured properly. 

Ensure that the Alcatel 7250 switch has a route to the TFTP server. The switch and the TFTP server

must be in the same subnet if you do not have a router to route traffic between subnets. Use the

ping command to check connectivity to the TFTP server. 

Ensure that the f irmware to be downloaded is in the correct directory on the TFTP server. 

Ensure that the permissions on the file are set correctly. Permissions on the file should be at least

read for the specific username. 

A power outage (or other problem) during the download procedure can corrupt the Flash code. If

the Flash code is corrupted, you can connect to the Alcatel 7250 through the console port and

download the application in the Loader by using the download application command.

 Downloading a Firmware CES Image Using TFTP

To download a firmware image for the 4 port DS1/E1 CEM-1 module to the Alcatel 7250 from a TFTP

server, proceed as follows: 

Step 1. Insert the module into slot 4 or 5 of the Alcatel 7250.

Step 2. Copy the CES firmware image file to the appropriate TFTP directory on the

workstation. 

Step 3. Log into the Alcatel 7250 through the console port or through a Telnet session. Ifyou log in using Telnet, your Telnet session will disconnect when you reset the

Alcatel 7250 to run the new firmware.

Step 4. Make sure there is enough free space on the device file system. Use “dir”

command for this. Free disk space should be at least 0.5MB larger then the

downloaded firmware size. 

7250#dir 

Example: 

7250#dir Listing Directory flash:/: 

d S 2048 Jun 30 2005 17:56 Boot/ 

d S 2048 Jan 1 1993 00:04 Etc/

Free disk space 5655104 

Step 5. If there is not enough free space, delete unnecessary files. This is done by using

“del” command. 

7250#del  

Example: 

7250#del /Boot/Oldimage.bin 

Step 6. Download the CES firmware from the TFTP server using the copy firmware 

command in Privileged (Enable) mode:

T-Metro#copy firmware  []

Example: 

7250#copy firmware tftp://192.192.54.0/CES-D310.bin 

NOTE The Alcatel 7250 remains operational while the image is downloaded.

The firmware image is downloaded into the /Boot directory .

Step 7. Enter the show firmware command to check which versions exist on the Alcatel

7250 file system.

Step 8. Update firmware version on the specific CES module inserted into one of the slots

using update firmware command in Privileged (Enable) mode.

7250#update firmware [force]  file-name

Example: 

7250#update firmware 1/4 file-name CES-D310.bin 

NOTE The Alcatel 7250 device remains operational while the firmware image is

updated. The CES card is not active during this operation. 

NOTE The force option in the update firmware command causes a complete reset of

the 4 PORT DS1/E1 CEM-1 card. It should be used carefully after failure of

the update of the CES image on the card (this could happen due to power

failure or restart of the device during the update operation).  

Step 9. Restart the device to activate the CES card with the new version (alternatively,

remove and reinserted the CES card for a complete reset).
