3Com CS/2500 manual Cabling the Server, To the Network, Turning on the server

2-4 CHAPTER 2: INSTALLATION

Mounting on the Wall	You can mount the server vertically on a wall using a wall mount kit
	(3Com part number 3C760).
	When mounting the server vertically, place the server in the vertical
	stand with the rear panel pointing to one side. Be sure that the side with
	the exhaust openings points up. When you view the front panel in this
	position, the reset switch is closest to the floor. If you are mounting a
	CS/2600, make sure the diskette drive is accessible.
Cabling the Server	Attach cables to the server’s network interface connectors, serial
to the Network	connectors, and power connector, all located on the back panel, before
	turning on the server.
	CAUTION: Be sure the server is turned off before you attach any
	cables. Check the AC power switch on the back panel to make sure the
	O side is pressed in. Connecting or disconnecting the cable between the
	server and its network interface while the server is on can cause
	damage.
Cabling Hosts,	Connect the server to hosts, terminals, and modems through serial port
Terminals, and	connectors J0 through J9. You can buy cables from 3Com or use your
Modems	own cables. The communications server acts as a DCE device and can
	be attached to a DTE device, such as a terminal, host, or printer, using a
	straight-through cable. If you want to connect the server to a DCE
	device, such as a modem, use a null modem cable. For wiring
	information, refer to Appendix A, “Pin Assignments.”
	If you configure one port as a console port (J0 is the default) and enable
	the monitor in firmware, that port cannot be used for another type of
	device. For more information, see “Cabling a Console” on page 2-5.
	You can connect either RS-232-D or RS-422-compatible devices to the
	serial ports. To connect an RS-422 device, you must reconfigure the port
	for RS-422 operation. For more information, refer to “Changing Port
	Configuration” on page 4-13.
	Multiprotocol communications server software, version 6.1 and later,
	sets the following default configuration for each serial port:
