Installing in the
Extended Chassis
To install the DPE module into the NETBuilder II Extended chassis, follow these
steps. If you own the 4- or 8-Slot chassis, refer to the previous section.
Although it is not required, 3Com recommends that you turn off the system
before you install or remove a DPE module. If you do not turn off the system,
the bridge/router will automatically reset when you install the DPE module.
You will need a small, flatblade screwdriver.
1 Insert the module into the left-most slot marked A.
2 Hand tighten the captive screws, then gently tighten them with a small
(1/8 in. – 3/16 in.) screwdriver. Do
not overtighten the screws.
A solid connection of the front panel to the chassis is required for proper
operation. Do
not use the screws to force the board into place.
You are now ready to install the I/O modules. Refer to the appropriate I/O
module installation guides. After installing your I/O modules, refer to the next
section, “Connecting a PC, Terminal, or Modem.”
