Serial number label

Serial number example: S/N:1BK12345 MAC address example: 0800021A4B5C You will need this information if you have to contact your network supplier. The MAC address is also encoded in the HSSI module’s EEPROM. Use the procedure in

Appendix B, “Displaying the MAC Address,” to display the MAC address encoded in the EEPROM.

Installing the HSSI Module

Use this procedure to install the HSSI module into the NETBuilder II base system. You will need a small ﬂathead screwdriver.

NOTE: There ar e two versions of the NETBuilder II 4-slot and 8-slot chassis. The older, single-

wide versions of the NETBuilder II 4-slot and 8-slot chassis have two ﬂipper ejectors for each module. The newer, dual-wide versions have one ﬂipper ejector for each module, except for the top slot which is reserved for the CEC module. When the term “dual-wide NETBuilder II chassis” is used in this manual, it refers to a chassis with only one ﬂipper ejector per module.

1. Select an I/O slot in which to install the HSSI module.

You can install the module in any available I/O slot in the rear of the NETBuilder II base system. The top slot is designated for the CEC module only.

2. Remove the blanking plate from the I/O slot you have selected for the HSSI module.
