Chapter 2 Switch Installation
Verifying Switch Operation
• Before you connect the switch to a power source, note these power consumption specifications:
– Cisco ME 3400G-12CS-AC switch:
65 W (typical), 80 W (maximum), 222 BTUs per hour (typical), 273 BTUs per hour (maximum)
– Cisco ME 3400G-12CS-DC switch:
55 W (typical), 70 W (maximum), 188 BTUs per hour (typical), 239 BTUs per hour (maximum)
– Cisco ME 3400G-2CS switch:
15 W (typical), 20 W (maximum), 51 BTUs per hour (typical), 68 BTUs per hour (maximum)
– Cisco ME 3400-24TS-AC and DC switches:
25 W (typical), 30 W (maximum), 86 BTUs per hour (typical), 102 BTUs per hour (maximum)
– Cisco ME 3400-24FS-AC switch:
50 W (typical), 65 W (maximum), 171 BTUs per hour (typical), 222 BTUs per hour (maximum)
Verifying Switch Operation
Before installing the switch in a rack, on a wall, or on a table or shelf, you should power the switch and
verify that the switch passes POST.
• To power on the AC switch, connect one end of the AC power cord to the AC power connector on
the switch, and connect the other end of the power cord to an AC power outlet.
• To power on a DC switch, see Appendix C, “Connecting to DC Power.”
When the switch powers on, it automatically begins the POST, a series of tests that verifies that the
switch functions properly. When the switch begins POST, the system LED slowly blinks green. When
POST completes, the system LED blinks amber. If POST fails, the system LED remains amber. If POST
completes successfully, the system LED rapidly blinks green.
POST failures are usually fatal. Call Cisco Systems if your switch does not pass POST.
Powering Off the Switch
After a successful POST, disconnect the power cord from the switch. Install the switch in a rack, on a
wall, on a table, or on a shelf as described in the “Installing the Switch” section on page 2-5.
