Chapter 5. Maintaining the B24X Hardware
This chapter provides instructions for maintaining the B24X hardware.
Attention:
The procedures in this manual are for qualified service personnel.
Hardware maintenance schedule
The B24X switch hardware components require minimal maintenance. You should
clean the fiber-optic connectors on fiber-optic ports and the connected fiber cable
each time you disconnect the cable.
You can replace the following hardware components as needed:
v
Fiber optic modules (SFP+ transceivers)
v
Power supplies
v
Fan tray
Replacing a fiber optic module
You can remove an SFP or SFP+ from a port and replace it with a new one while
the B24X is powered on and running.
This section provides information about the following tasks:

“Removing a fiber optic module”
v
“Installing a new fiber optic module” on page 32

“Cabling a fiber optic module” on page 32
Removing a fiber optic module
You can remove a fiber SFP+ (also called a Small Form-factor Pluggable Plus) or
an SFP from a port while the B24X is powered on and running.
Before removing a fiber optic module, have the following on hand:
v
An ESD wrist strap with a plug for connection to the ESD connector on the
B24X.
CAUTION:
For safety reasons, the ESD wrist strap should contain a series 1 meg ohm
resistor.
v
The protective covering that you removed from the fiber optic module when you
initially installed the module.
Complete the following steps to remove a fiber optic module from a Gigabit
Ethernet or 10-Gigabit Ethernet port:
1. Put on the ESD wrist strap and ground yourself by attaching the clip end to a
metal surface (such as an equipment rack).
2. Disconnect the fiber cable connector from the port connector.
3. Insert the protective covering into the port connector or connectors.
4. Pull the fiber optic module out of the port by pulling the latch (
1
) forward,
away from the front panel of the module as shown in Figure 12 on page 32.
This unlocks the module from the front panel. On 1000BaseSX ports, the latch
is enclosed in a black sleeve, and on 1000BaseLX ports, the bail latch is
enclosed in a blue sleeve.
