Installation
Express 510T Switch

3 Set the switch in the equipment rack and ensure there is ade-
quate ventilation (see “Allow adequate ventilation” in “Posi-
tioning the Switch”, p. 7).
4
Screw the mounting brackets securely to the equipment rack.
Ambient temperature
If the switch is installed in a closed or multi-rack assembly, the oper-
ating ambient temperature of the rack environment may be greater
than the ambient temperature of the room. Care must be taken to en-
sure the temperature of the rack environment does not exceed the rec-
ommended operating temperature for the switch.
Installing a Module
Introduction
You can increase the connectivity options of your switch by installing
a module.
Warning
Modules are not designed to be installed in, or removed
from, the switch while it is in operation. You must
power off the switch before attempting to install a mod-
ule.
Static-free working area
The module’s printed circuit board is an Electrostatic Sensitive De-
vice and should only be handled in a static-free working area, other-
wise the printed circuit board may fail or be degraded.
Avoiding damage to the
circuit board
If you remove the plate covering the slot on the front of the switch,
for example, to install or remove a module, follow this procedure to
avoid damage to your printed circuit board:
Warning
The plate must not be removed unless the switch has
been disconnected from the main power supply.
1
Disconnect the switch from the main power supply.
2
Ground the switch before you handle the printed circuit board.
3 Connect yourself to a non-painted/non-isolated part of the
grounded switch (for example the back panel) using a wrist
strap with 1M
Ω
resistance to ensure that you carry the same
electrostatic charge as the enclosure.
4 Now you can remove the plate covering the slot.
