Mcdata 4400 cannot be pinged

I this a new or production switch?

I cant remember if the 4400's had a serail port to connect to.  Was thinking the web server needed to be restarted but if you power cycled it and it didnt work then there is something wrong with it.

You can try these:

Management Ports

The McDATA Sphereon 4400 also provides for management through either a DB-9  RS-232 serial port or through a 10Base-T and 100Base-T.

Connecting to the DB-9 RS-232 maintenance port requires a null modem cable  and the following connection settings:

• 115200
• 8 data bits
• No parity bit
• 1 stop bit
• No flow control

The default IP address of the ethernet management port is 10.1.1.10/8.

Reset Button

The reset button performs two functions; a switch reset and an Initial  Machine Load (IML).

Switch Reset

A reset is disruptive to Fibre Channel traffic and resets  the following:

• Microprocessor and functional logic for the control processor (CTP) card and  reloads the firmware from FLASH memory.
• Ethernet LAN interface, causing the connection to the browser PC or  management server to drop momentarily until the connection automatically  recovers.
• Ports, causing all Fibre Channel connections to drop momentarily until the  connections automatically recover. This causes attached devices to log out and  log back in, therefore data frames lost during switch reset must be  retransmitted.

Complete the following steps to reset the switch:

1. Press and hold the RESET button for ten seconds.
   - After holding the  button for three seconds, the amber ERR LED blinks at twice the unit beaconing  rate.
   - After holding the button for ten seconds, the ERR LED stops blinking,  and all front panel LEDs illuminate.
2. Release the button to reset the switch. During the reset:
   - The green PWR  LED on the switch front panel illuminates.
   - The amber ERR LED on the switch  front panel blinks momentarily while the switch is tested.
   - The green LED  associated with the Ethernet port blinks momentarily while the port is  tested.
   - Green and amber LEDs associated with Fibre Channel ports blink  momentarily while the ports are tested.
   - The switch-to-browser PC (or  management server) Ethernet link drops momentarily.

Initial Machine Load

An Initial Machine Load (IML) or reset is performed at the switch front panel  using the RESET button. An IML does not cause power-on diagnostics to execute  and is not disruptive to Fibre Channel traffic. An IML:

• Reloads switch firmware from FLASH memory.
• Resets the Ethernet LAN interface, causing the connection to the browser PC  or management server to drop momentarily until the connection automatically  recovers.

Complete the following steps to IML the switch:

1. Press and hold the RESET button (about three seconds) until the amber ERR  LED blinks at twice the unit beaconing rate.
2. Release the button. During the IML, the switch-to-browser PC (or management  server) Ethernet link drops momentarily.

hope this helps
