AT-CV5M01Management Card

The AT-CV5M01Management Card provides a CPU subsystem for theAT-CV5000chassis as well as theAT-S70management software preinstalled that allows you to configure and monitor the status of the converter line cards. For more information about theAT-S70management software, refer to theAT-S70 Management Software User’s Guide.

The AT-CV5000chassis is shipped without anAT-CV5M01Management

Card and therefore is by default an unmanaged chassis.

Note

The AT-CV5M01Management Card ishot-swappableand you can insert it in any line card slot without powering OFF the chassis.

The AT-CV5M01Management Card, as shown inFigure 6, features the following components:

One RS-232terminal port with aDB-9connector for a local management session

One 10/100Base-TXtwisted pair port with anRJ-45connector for a remote management session

One recessed CPU RESET button

Six CPU status LEDs

The default settings for the RS-232terminal port are:

Baud rate: 115200 bps (range 2400 to 115200 bps)

Data bits: 8

Parity: None

Flow control: None

These default settings are for a DEC VT100 or ANSI terminal, or an equivalent terminal emulation program.

Note

This terminal port does not allow you to connect to any module present in the expansion slot located in the rear of the chassis. To connect to a module in the rear expansion slot, you must use the RS-232terminal port on the LED interface card, as described in“LED Interface Card” on page 21.

The 10/100Base-TXtwisted pair port on the management card allows you to establish a remote management session and has a maximum operating distance of 100 meters (328 feet). The port has an8-pinRJ-45connector. For the port pinouts, refer to“RJ-45 Twisted Pair Port Pinouts” on

page 103.

The twisted pair port is 10/100Base-TXIEEE 802.3uAuto-Negotiationcompliant and is capable of both 10 megabits per second (Mbps) and 100 Mbps speeds. You can set the port speed manually through theAT-S70management software or allow the port to set it automatically. With AutoNegotiation, the management card automatically matches the highest possible common speed between the port and the Ethernet hub or switch. For example, if the Ethernet hub or switch is capable of only 10 Mbps, the management card sets the port connected to the end node to 10 Mbps.

Note

Auto-Negotiationis the default setting on the twisted pair port on the management card. To deactivateAuto-Negotiationand set the speed manually, refer to theAT-S70 Management Software User’s Guide.

The twisted pair port on the management card can operate in either halfor full-duplexmode. The twisted pair port is IEEE802.3u-compliantand willAuto-Negotiatethe duplex mode setting. You can disable AutoNegotiation and set the duplex mode manually using theAT-S70management software.

Note

In order for the twisted pair port on the management card to successfully Auto-Negotiateits duplex mode with an end node, the end node should also be usingAuto-Negotiation.Otherwise, a duplex mode mismatch can occur. Therefore, when you connect an

end node with a fixed duplex mode of full-duplexto a management card port, you should use theAT-S70management software to disableAuto-Negotiationon the port and set the port speed and duplex mode manually.

For 10 Mbps operation, Category 3 or better, 100 Ohm shielded or unshielded, twisted pair cabling is required. For 100 Mbps operation, Category 5 or Enhanced Category 5 (5E), 100 Ohm shielded or unshielded, twisted pair cabling is required.

The recessed CPU RESET button allows you to reset only the management card. You may need to reset the management card after upgrading the firmware or after you have made a configuration change that requires resetting the module to activate the change.

Note

This reset button does not reset the line cards and/or the module installed in the expansion slot at the rear of the chassis.

The status LEDs located on the AT-CV5M01Management Card are described inTable 2.
