GRF 400/1600 Getting Started - 1.4 Update 2
Rack Mount and Power On Procedures
Powering on the GRF 1600
Powering on the GRF 1600
As described earlier in this chapter, the initial start-up of the GRF requires a directly-attached
terminal for logging in as
root
. The terminal should be connected BEFORE you power on the
GRF so you can monitor the start up and boot messages that begin immediately. The GRF 1600
is powered by either 1100W AC or negative 48V DC power supplies.
This section includes procedures for both types of power supply:
–
applying power to AC power supplies
The GRF chassis does not have a power on/off switch. The AC power supply does not
have an on/off switch. As a result, when the AC power cord is plugged in to a power outlet,
the GRF is powered on. It takes a few seconds for the power supply(s) to cycle before
power is supplied to the back panel and the media cards.
–
wiring and applying power to DC power supplies
A GRF 1600 DC power supply does have a power on/off switch on its front panel. After
the DC wiring set is attached and carries current, this switch controls the application of
current to the DC power supply.
When the GRF is powered on, it begins to boot. You can see the boot messages displayed on
the terminal screen. As it boots, the GRF runs a series of internal diagnostics. The first time a
GRF is powered on, the boot process runs a system configuration script. In this script you
assign the GRF a host name, configure the maintenance Ethernet, and optionally specify a
syslog server. The GRF supports remote logging via a syslog server as well as local logging
(and dumps) to an external flash device.
Media cards will boot automatically and come up ready to operate.
The speaker on the control board faceplate emits audible beeps as the board boots.
Redundant power supplies
Installing redundant power supplies ensures against failures of individual units in the chassis.
If possible, attach each power supply into a different power source.
Power supply failure notification
If a GRF 1600 power supply fails, you will see failure messages on-screen at the user interface.
The
gr.console
log file will also contain related messages. The PS1 or PS2 amber LED on
the control board will light, indicating a power supply failure. If you do not already have a
replacement unit, order one from Lucent.
Warning:
A failed power supply must be replaced by certified personnel only.
