Updating The Scs Clock; Enabling Ntp; Disabling Ntp; Configuring Serial Port Settings - HP 16-port SCS Installation Instructions Manual

Updating the SCS clock

The SCS supports the network time protocol (NTP) protocol. When NTP is enabled, the battery-backed real-time clock
on the SCS updates immediately after NTP is enabled, each time the SCS reboots, and, optionally, at specified
intervals.
You can specify one or two NTP servers to provide the time. An NTP server can be an external or internal server that
you supply. The primary server is queried for the time first. If it does not respond with a valid time, the secondary
server is queried. The second server will be queried for status even if a valid time was obtained from the primary
server.

Enabling NTP

Issue an NTP command with the Enable parameter.
ntp enable [ip=<prim_add> [,<sec_addr>]] [update=<hours>]
If this is the first time NTP is being enabled, you must specify at least one NTP server address.
If you want the time to be updated periodically, specify an update interval of up to 99 hours. If you specify a zero
interval value (which is the default), the time is updated only when the SCS reboots.
When you enable NTP, you are prompted to confirm or cancel the operation.

Disabling NTP

Issue an NTP command with the Disable parameter.
ntp disable

Configuring serial port settings

A console target device (TD) can be a serial-managed Linux (or other UNIX) server, router, firewall, or other
supported serial device.
By default, SCS ports are configured with the settings listed in Table 3-2.
Table 3-2 Default port settings
Parameter
Target device
Name
Baud rate
Bits per character
Parity
Stop bits
Flow control
Time-out
CLI access character
Power
Most of these settings are standard serial port operating characteristics.
The CLI access character parameter specifies how you access the CLI. For more information, see "CLI mode."
The Power parameter instructs the SCS to monitor the state of a specified control signal. Signal transitions can be
configured to trigger SNMP traps. The parameter value indicates an inbound control signal Clear to Send (CTS), Data
Carrier Detect (DCD), or Data Set Ready (DSR) and the state of that signal (low or high). When the defined signal is
true, the SCS interprets it as a power on condition for the attached device. When the signal is false, a power-off
condition for the device is assumed. The signal specified for flow control cannot be used for power control.
