Follow the guidelines in Table A-8when installing ONline Edge Router modules in an ONcore 10-slot or 17-slot hub.

.

Table A-8 ONcore Hub Capacities for ONline Modules

Number		Maximum Number of
of Power	Slots per	Modules (both serial
Supplies	Hub	ports in use)

Maximum Number of Modules (one serial port in use)

1	10-Slot	7	10

	17-Slot		14

21	10-Slot	10	10
	17-Slot	14	17

3	10-Slot	10	10

	17-Slot	17	17

4	10-Slot	10	10

	17-Slot	17	17

	1 If hub is set to fault-tolerant mode, apply restrictions for 1 power supply.

Cable Pinouts	Use the information in this section to ensure that the cables and connecting
	hardware meet requirements. For proper operation, use only approved
	cables when you install all equipment.
	The console and auxiliary ports on the Edge Router module require a
	mini-DIN to DB-25 serial port adapter cable. You can use a cable that meets
	the specifications described in this section or you can purchase the 3Com
	OpenHub Management Cable (Part Number OHPMGT-CAB).
	The OpenHub Management Cable has a:

■Mini-DIN connector — Plugs into the console or auxiliary port on the Edge Router module.

■DB-25 connector — Plugs into the cable of the peripheral device.

To connect the mini-DIN to DB-25 cable to another DTE device, use a null modem adapter.
