Installing the console switch 22
• Blinks Morse code SOS—The power supply whose indicator LED is not blinking does not have
power or has failed.
• Blinks consistently—A firmware upgrade is in process.
Rear panel Ethernet connection LEDs
The rear panel of the switch features two LEDs that indicate the Ethernet connection for LAN1 and two
LEDs that indicate the Ethernet connection for LAN2.
The green LEDs illuminate when a valid connection to the network is established and blink when activity
occurs on the port.
The bi-color LEDs either illuminate green or amber.
• Green illumination—The communication speed is 1000 Mbps.
• Amber illumination—The communication speed is 100 Mbps.
• No illumination—The communication speed is 10 Mbps.
Virtual media and serial interface adapters LEDs
Typically, interface adapters feature two LEDs:
• Power LED—Illuminates green when the interface adapter is connected and receiving power.
• Active LED—Illuminates green when the interface adapter is in an active session.
• Active LED—Blinks green when the interface adapter firmware is flashed. Do not interrupt power to
the interface adapter during a firmware update.
HP IP Console Viewer overview
If you want the HP IP Console Viewer software to configure your console switch, you must install it. The HP
IP Console Viewer enables you to remotely organize and manage your local KVM and serial appliances,
as well as any device connected to them within your datacenter. For more information, see the HP IP
Console Viewer User Guide included on the CD provided with this product.
NOTE: The local console port does not require the HP IP Console Viewer software for
operation. The local console port uses the local console UI. For more information, see
Configuring the console switch (on page 30).
The console switch system uses Ethernet networking infrastructures and the TCP/IP protocol to transmit
keyboard, video, and mouse information between operators and connected computers. Although 10Base-
T Ethernet can be used, a dedicated, switched 100Base-T or 1000Base-T network provides improved
performance.
