Installing in the 4- or 8-Slot Chassis 1-3
Installing in the 4- or
8-Slot Chassis
To install the DPE module into the NETBuilder II 4- or 8-Slot chassis, follow these
steps. If you own the Extended chassis, refer to the next 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 top slot.
Although the figure shows an 8-Slot chassis, the procedure for the 4-Slot
chassis is exactly the same.
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
“Connecting a PC, Terminal, or Modem” on page 1-5.
