Installing A Power Supply Unit (PSU)
All AC and DC versions of this equipment must be earthed.
PSUs can be hot swapped. When swapping PSUs, the SwitchBlade 8 (AT-SB4108) will
continue to operate as long as two functional PSUs remain in place. The SwitchBlade 4
will continue to operate as long as one functional PSU remains in place.
Follow these steps to install a PSU:
1.
Read the safety information
The SwitchBlade Safety and Statutory Information booklet includes all
relevant safety information. A copy of the safety booklet is supplied with
each PSU. It can also be found on the CD-ROM that ships with every
switch controller and every chassis, or can be downloaded from
www.alliedtelesyn.co.nz/support/switchblade/.
2.
Gather the tools and equipment you will need
To loosen or secure the PSU's mounting screws you will need a Phillips #2
screwdriver.
3.
Choose a PSU bay
PSU bays should be filled from left to right.
Unless replacing an existing PSU, choose the empty PSU bay that is nearest
to the chassis's front left-hand corner.
4.
Prepare the PSU
In an antistatic environment, remove the PSU from its packing material. Be
sure to observe ESD precautions.
Do not attempt to install a PSU without observing correct antistatic
procedures. Failure to do so may damage the chassis or PSU. If you are unsure
what the correct procedures are, contact your authorised Allied Telesyn
distributor or reseller.
An ESD socket is provided on the front panel of the SwitchBlade chassis. The socket is
designed to be used in conjunction with an ESD wrist strap (see Figure 1 on page -4).
