Installing the Switch

Installation Procedures

Installing the Switch

If the self-test does not complete correctly, the LED display will be different

than what is described above; for example:

■ The Fault and Test LEDs stay on for more than 60 seconds.

■ The Fault and Test LEDs start blinking.

Refer to Chapter 4, “Troubleshooting” for diagnostic help.

3. (Optional) Reverse the air flow

In a 4-post rack mounting, you must ensure that the air flow direction in a 6600

Switch is from the cold side to the hot side of the aisle. If necessary, reverse

the direction of the fans to provide adequate switch cooling. For example,

reversing the air flow direction is required in a port-side mounting in which

the port side of a 6600 Switch faces the cold aisle and the air flow is from the

power (hot aisle) to the port (cold aisle) side.

The default air flow direction is from the power to the port side as shown in

Figure 2-1.

Figure 2-5. Default air-flow direction in 6600 Switches is from power to ports.

Note Although reversing the direction of air flow on a switch is a hot swap opera-

tion, HP ProCurve recommends that you perform the operation after powering

down the switch.

If you remove the fan tray while a switch is running, you have only three

minutes before the switch powers down the ports. To re-enable the ports, you

must reset the switch either by pressing the Reset button or powering off and

on the switch.
