IBM SAN04B-R - System Storage Router, Инструкция по установке, обслуживанию и эксплуатации, Страница: 74 / 103

CAUTION:
Data processing environments can contain equipment transmitting
on system links with laser modules that operate at greater than
Class 1 power levels. For this reason, never look into the end of an
optical fiber cable or open receptacle. (C027)
To remove and replace SFP modules from the router, complete the appropriate
steps below, depending on the type of SFP used. You must first verify that there is
no activity on the router, then remove the cables, and finally remove the SFPs.
Once you have installed the new SFPs, you must connect the cables and then
verify that the SFP is functioning correctly.
Removing SFP modules
If the router is already configured, replace only one SFP at a time to avoid mixing
up the cables and their associated ports.
Note: In the illustrations below, the SFPs and cables are shown outside of the
router’s ports for clarity, and are not oriented in the direction that they are
installed in the router. The ports are also shown installed in a generic unit
with a double row of ports, while this router has only a single row of ports.
Removing fiber optic cables:
Attention: Do not bend a fibre cable to a radius less than 5 cm (2 in.); you can
damage the cable. Tie wraps are not recommended for optical cables because they
can be easily overtightened, causing damage to the cable.
Follow the steps below to remove a fiber optic cable.
1. Verify that there is no activity by viewing the router LEDs. For details about LED
activity on the router, see “LEDs on the port side of the router” on page 30.
2. Press down and hold the lever (see Figure 16) to release the cable latches.
3. Carefully pull on the connector to remove the cable from the SFP module, as
shown in Figure 17 on page 47. Note that this procedure is the same, whether
the SFPs are plastic tab type as shown, or wire bale SFPs.
