8.4 Installing and Removing a Power Supply

The HP 9300 series of switches do not have an on/off power button. They are powered on when
the power cord is connected to a power supply and to a power source. To turn the system off,
you unplug the power cords. Redundant power is an option. Each power supply must connect
to a separate AC power source for additional power redundancy.
The HP 9304M comes standard with one power supply, which is enough to provide adequate
power for any combination of modules.
The HP 9308M can contain from one to four power supplies and comes standard with one power
supply. One supply is adequate for devices with one, two, or three modules (including the
management module). If the 9308M contains four or more modules, you need at least two power
supplies. Two power supplies is sufficient if the chassis contains fewer than four 24-port 100 FX
modules. If the 9308M contains four or more 24-port 100 FX modules, you need at least three
power supplies.
The HP 9315M can contain from one to four power supplies and comes standard with two power
supplies. One supply is adequate for devices with one, two, or three modules (including the
management module). If the 9315M contains four or more modules, you need at least two power
supplies. Two power supplies are sufficient if the chassis contains fewer than four 24-port 100
FX modules. If the 9308M contains four or more 24-port 100 FX modules, you need at least three
power supplies.
The ProCurve 9300 series switches can remain running while a power supply is being installed
or removed. However, to prevent injury to yourself or the equipment, the power supply should
not be connected to a power source during the installation or removal process.
When you power on a switch that has multiple power supplies, make sure you apply power to
all the supplies at the same time. Otherwise, the device might not boot or it might repeatedly
display a warning message stating that you need to add more power supplies.
Important:
The HP ProCurve 9304M and 9308M use the J4147A power supply. The HP ProCurve 9315M
uses the J4875A power supply. Be sure to use the correct power supply for your switch model.
The two power supplies are not interchangeable.
Installing a Power Supply
To install a power supply in a ProCurve 9300 series chassis, do the following:
1. Use a screwdriver to remove the blank power supply face plate. This will expose the empty
power supply slot. (If you are replacing a defective power supply, follow the instructions
in the previous section for removing a power supply.)
2. Remove the power supply from its packaging; or, if the power supply is connected to a
power source, remove the power cable.
3. Holding the bar on the front panel of the power supply, insert the power supply into the
empty power supply slot using the module guides provided on either side of the compartment
(Figure 8-7).
